gold leaching tank concrete

small gold leaching circuit design

The gold cyanide leaching mill site is centrally located with respect to the mine, water supply and improved highway. This selection reduced both the length of the haulage road from mine to mill and main water supply line to a minimum. The location provided a sloping mill site, adequate tailings disposal area, housing space for both mine and mill supervisory employees and operating labor, plus a suitable area for assay office, machine and maintenance shops, lime kiln, power plant, in addition, strip for small planes for emergency usage. A tramway was installed to deliver ore from the mine portal to a point accessible for truck haulage for six miles to the mill. The water supply was developed by wells in the gravel of a river-bed and pumped four miles through a 4-inch line to the mill site.

The flowsheet was developed from laboratory tests conducted by the 911Metallurgist, and is briefly as follows: Ore from the coarse bins is fed by a continuous feeder and conveyed to crushing section. Lime is fed on coarse ore conveyor due to large amount required and for ease of addition. A wedge bar grizzly removes the minus 1 material ahead of the 10x 20 Jaw Crusher which is in open circuit with a doubledeck 3x6 Vibrating Screen and a 3 cone crusher. The upper deck of the 3 x 6 screen has a heavy gauge space cloth to reduce wear on lower opening screen. The crushed material is conveyed to mill storage bins by one fixed and one travelling belt conveyor so arranged to allow ore storage in either of the two fine ore bins, with provisions to permit storage in other additional bins in case of mill expansion.

Ore from mill bins is fed to each of the 5 x 8 Steel Head Ball Mills by variable speed belt ore feeders. The ball mills are in closed circuit with 36 flared tank spiral classifiers. The overflow from each classifier at 95% minus 100 mesh at 25% solids flows by gravity to a 30 diameter by 8 deep primary thickener. The thickener overflow, pregnant solution flows to the precipitation plant below the mill. The underflow from each primary thickener is pumped to a bank of three 16 diameter x 14 deep, cyanide side airlift rake agitators in series. The pulp from the third agitator in each circuit flows to the first counter-current washingthickener of a series of four single sealed tray, two compartment thickeners. Each compartment is connected to an individual Adjustable Stroke Diaphragm Pump for the proper control and metering of the pulp between the tray thickeners. The underflows from the two compartments of the fourth and final thickener are pumped to two 6 x 4-disc Disc Filters.

The filter cake is repulped and pumped at high density to tailing pond. Fresh wash water is added to the fourth thickener to make up loss of solution due to evaporation and for solution contained in filter cake. Water from tailings pond contains a small amount of cyanide and is reclaimed for use as wash water to the washing thickeners or for mill supply usage.

The design considerations were to provide ease of ore delivery by truck, minimum capital investment for equipment and construction items, contingent with highest economic recovery, and for low operation and maintenance expense. General construction incorporated best usage of locally available materials and labor, due to the remote location.

The coarse ore bins were located to allow access for trucks without extreme road-way grades and with ample space at unloading points for trucks to turn and dump without lost time. These bins were designed for construction from 8 and 10 square sawed timber framing and 3 wood linings, which were available at reasonable cost. Four bin sections were provided for receiving and ore storage, plus one section for locally burned lime.

The crushing section was located to reduce conveyor length from and to storage points and permit minimum excavation and retaining walls in the sloping portion of the mill site. However, excavation and retaining walls did not affect costs to the usual extent due to low cost of local labor. All retaining walls were made from limestone masonry, using portland cement.

The equipment for crushing plant was selected to allow mill to be expanded to 400 tons per day without alterations or additions, except for the two additional fine ore bins. Space was provided for the expected increase in capacity.

The fine ore bins are round tanks, 16 diameter by 18 deep. These are of bolted design for ease of erection and for possible salvage value later. All mill solution and water storage tanks are also of bolted steel type. These tanks all being mounted on masonry piers with space provided for access to the ore feeders installed below. Automatic Samplers are used at belt feeder discharge to cut interval samples.

The grinding section allows ample working space around both ball mills and classifiers. Ball mill foundations being reinforced concrete to amply support the mills. The millswere equipped with combination drum scoop feeders and with welded steel scoop boxes, which have removable covers for access and inspection. The arrangement of the primary thickeners, rake agitators and washing tray thickeners was made to provide gravity counter flow of solution as desired with diaphragm pumps for the control of the pulp. The compact arrangement with walkways allowed operators easy access to the operating control points and unobstructed view of the operating area.

All thickeners and agitator tanks were of bolted design and mounted sand fills retained by circular masonry retaining walls, plus masonry retaining walls for the thickener underflow piping tunnels. A concrete floor, slightly above the ground line in the tank area was provided with drains to sump located between the four washing tray thickeners. This sump being connected to a SRL Pump to handle any solution spillage or for use as a transfer pump in case of the necessity to empty any thickener or agitator tank.

Detailed consideration was given to all pipe lines to allow adequate size and gradients for solution and pulp flows, together with compact, neat arrangement. All piping being bent in long radius, where bends were necessary and with pipe tees, where sharp turns were required. Clamp type joints were selected, both for ease in installation and possible removal for clearing in case of pipe stoppage. Due to arid and warm climate in the area no buildings were provided for the main plant. Corrugated sheet metal roofs supported by light weight steel, were installed over crushing section, fine ore bins, grinding section and over walkways and filter section to protect operators from the sun.

The precipitation plant equipment was installed in a masonry building with corrugated roof supported by steel roof trusses. This plant provided vacuum leaf clarification, zinc dust precipitation, and filtration, plus necessary solution and vacuum pumps. Precipitate drying, and smelting furnaces were installed in a room separate from the precipitation section.

Power plant for the mill included three diesel electric generator units, one being for standby service. Three phase, 60 cycle, 440 volt, and single phase, 60 cycle, 220 volt current was generated for power and lighting.

The design and construction period for this complete plant required approximately four months, including initial start-up period, for a final check on metallurgy, and minor alterations and adjustments.

Recognition of the various factors and problems, and their proper evaluation in the planning stages resulted in a substantial saving in construction costs, and in the subsequent operation of this plant.

gold ore tank leaching vs. vat leaching - pineer mining machinery

Tank and vat leaching involves placing ore, usually after size reduction and classification, into large tanks or vats at ambient operating conditions containing a leaching solution and allowing the valuable material to leach from the ore into solution.

In tank leaching the ground, classified solids are already mixed with water to form a slurry or pulp, and this is pumped into the tanks. Leaching reagents are added to the tanks to achieve the leaching reaction. In a continuous system the slurry will then either overflow from one tank to the next, or be pumped to the next tank. Ultimately the pregnant solution is separated from the slurry using some form of liquid/solid separation process, and the solution passes on to the next phase of recovery.

In vat leaching the solids are loaded into the vat, once full the vat is flooded with a leaching solution. The solution drains from the tank, and is either recycled back into the vat or is pumped to the next step of the recovery process. . Vat leach units are rectangular containers (drums, barrels, tanks or vats), usually very big and made of wood or concrete, lined with material resistant to the leaching media. The treated ore is usually coarse.

As mentioned previously tanks are equipped with agitators to keep the solids in suspension in the vats and improve the solid to liquid to gas contact.Agitation is further assisted by the use of tank baffles to increase the efficiency of agitation and prevent centrifuging of slurries in circular tanks

gold cil & cip gold leaching process explained ccd

Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks. CIL is slightly different from another gold extraction process called CIP or carbon-in-pulp process. In the latter case leaching takes place in tanks dedicated for leaching followed by adsorption onto carbon in tanks dedicated for adsorption.

Leaching can be assimilated to the principle of preparation of tea. When we add tea in hot water, the aroma of tea will dissolve in the water and not the tea leaves. So the aromas is found in liquid form and tea leaves remains in solid form in the hot water. Thus we can separate (solid-liquid separation) tea aromas from tea leaves (filtration for example). At this stage , we have been able to extract aromas of tea from the tea leaves by changing the physical shape of the tea aromas.It is the same principle used in the leaching of gold. The gold that is in solid form in the ores turned into liquid form with cyanide in the presence of oxygen. Thats the way gold is separated from the majority of its gangue. The second step is the adsorption of gold on the surface of the activated carbon. Following a natural phenomenon known around the world (positive charges attract negative charges) Gold sticking to coal. the coal loaded with gold and some impurities is then transferred to the elution where he undergoes a cold wash which removes certain impurities and then a hot wash. The solution from the hot wash is transferred to the electrolysis where pure gold is recovered.

Carbon-in-pulp (CIP) is the sequential leach then absorption of gold from ore. During the CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to dissolve gold into solution. In the absorption stage, this solution flows through several agitated tanks containing activated carbon. Gold absorbs onto the activated carbon, which flows countercurrent to the pulp, while screens separate the barren pulp from the gold-loaded carbon. Carbon-in leach (CIL) is a simultaneous leach and absorption process. The simultaneous leach and absorption phases of the CIL process were developed for processing gold ores that contain preg-robbing materials such as natural absorptive carbon. These reduce the gold yield by attracting gold meant for the activated carbon. Simultaneous leaching and absorption help minimize the problem.

Process Description. The first industrial CIP plant was installed inSouth Dakota. A CIP circuit utilizes the same flowsheet as an agitated leach circuit up to the point where the slurry discharges from the final agitated leach tank. At this point, the precious metal values arc recovered directly from the slurry onto granulated activated carbon in agitated CIP tanks The carbon is retained in the tanks by any one of several different types of screens through which the slurry discharges CIP circuits are typically designed with at least four tanks to prevent short-circuiting of sluny and allow sufficient retention time for recovery of all the metals. Although agitated leach tanks are used before CIP tanks, CIP and CIL circuits are considered as a separate process.

CIL circuits are similar to CIP circuits with the exception that leaching and extraction occur simultaneously in agitated leach tanks that also contain carbon and are equipped with carbon retention screens

The evaluation of agitated tank leaching verses CIP and CIL circuits is not as complex as the heap leach-agitated tank leach analysis. CIP and CIL circuits generally have lower capital and operating costs for gold ore bodies than agitated tank leach circuits. Silver ore bodies show better economics with agitated tank leach-Merrill Crowe circuits. This is because the volume of carbon that would have to be processed to recover economic levels of silver would increase the capital and operating cost of a CIP or CIL circuit above that of an agitated tank leaching/CCD/Merrill-Crowe circuit.

Counter-current leaching. leaching efficiency can be enhanced by the application of Le Chateliers principle. In summary, the lower the concentration of gold in solution, the greater the driving force for gold dissolution to occur, although in a mass transport controlled reaction it is debatable what role this plays in gold leaching. An alternative explanation for this phenomenon is the reversible adsorption of Au(I) cyanide onto ore constituents. The gold adsorption is reversed when the solution is exchanged for a lower-grade solution or when a material (such as activated carbon or suitable ion exchange resin) is introduced into the slurry, which actively competes for the Au(I) cyanide species. This effect can be exploited in practice by performing intermediate solid-liquid separation steps during leaching to remove high-grade gold solutions, and re-diluting the solids in the remaining slurry with lower-grade leach solution and/or with freshwater plusreagents. Successful applications of this principle have been used at the Pinson and Chimney Creek, Nevada (United States), and East Driefontein (South Africa) plants, and at other operations.

At many operating gold plants, an increase in gold dissolution is observed when a leach slurry is transferred from one type of process equipment to another (i.e., between leach tanks, thickeners, filters, pumps, and pipelines). This is explained by the different mixing mechanisms in the different equipment, coupled with other factors, such as changes in slurry percent solids, changes in solution composition, and the effects of pumping transfer (i.e., plug flow mixing).

Likewise, the benefits of the carbon-in-leach (CIL) process compared with leaching and carbon-in-pulp (CIP) have been clearly demonstrated both experimentally and in practice, even without the presence of interfering preg-robbing constituents in the ore. The CIL process results in improved conditions for gold dissolution as a result of the lower gold tenor, albeit at a cost of lower gold-on-carbon loading.

The process technology and equipment design are described in detail for the carbon-in-pulp process. A typical process flowsheet is given with a description of appropriate design criteria. Technical advantages and disadvantages as compared to the traditional countercurrent decantation process are discussed including some illustrative comparisons of capital and operating costs.

In the carbon-in-pulp process activated carbon is mixed with a ground ore plus water slurry in which gold and silver cyanides are dissolved. After the precious metals are adsorbed onto the carbon, the loaded carbon is separated from the pulp and stripped. The barren pulp is disposed of as tailings and the precious metals are recovered from the strip solution by electrowinning or zinc precipitation.

The carbon-in-pulp process is used to treat low grade gold and/or silver ores. The ore is first ground in a ball mill which operates in closed circuit with a cyclone or similar sizing device. This is done to produce a feed suitably sized so that subsequent leaching is rapid.

The ground ore overflowing the sizing device generally runs at 25 to 35 percent solids. First it is passed through a trash screen to remove tramp oversize, plastics, wood, and other debris. It is then thickened to a requisite 40-50 percent solids prior to leaching. This range of pulp density keeps the activated carbon suspended in the pulp and is suitable for the subsequent leaching operation.

Following leaching, the pulp flows into the carbon-in-pulp circuit which operates in counter-current fashion. Usually five stages of adsorption are employed. Traditionally, 6 by 16 mesh activated carbon is added to the number 5 carbon-in-pulp tank and advanced to the number 4 tank and so on by air lift. The pulp is advanced from the number 1 tank to number 1 tank and so on by a second series of air lifts.

One of the most important factors in the carbon-in-pulp process is the minimization of gold losses on fine carbon reporting to the tailings. To date, the most abrasion resistant plus surface-active carbon has been found to be coconut shell carbon. Normally, the carbon consumption will average between 0.1-0.02 kg carbon per tonne of ore feed.

The traditional process for gold recovery from cyanide leach liquors has been the countercurrent decantation process. Following leaching, countercurrent decantation takes place in a series of thickeners in which the leach pulp is washed by the countercurrent flow of barren solution. The classified pregnant solution is treated for gold recovery with zinc dust. The precipitate may be acid digested. It is then smelted into bullion bars. The barren solution from zinc precipitation is returned to the last thickener.

The most well known carbon-in-pulp plant remains the prototype Homestake plant in Lead, South Dakota. Operating since 1973, this facility treats 2130 tonnes of ore per day averaging 2.7 g gold per tonne. Homestake has also operated small silver carbon-in-pulp plants at Creede and Cripple Creek, Colorado since 1979.

simplified modelling of calcium leaching of concrete in various environments | springerlink

Deterioration of concrete structures subjected to aggressive water is often characterized by the leaching of calcium from hydrates. Since calcium leaching is a nonlinear phenomenon, which is influenced by a wide range of parameters, the residual service life of the structures affected by such deterioration cannot be predicted satisfactorily on the basis of experimental results alone. In order to provide more fundamental information on this phenomenon, a numerical model was developed. The model considers the thermodynamic equilibrium between the pore solution and the various hydrated phases. In addition, the deterioration mechanism is treated from a macroscopic point of view. This model has been first validated on cement paste samples leached by deionised water. Second, extension to other kinds of environment and materials was done by considering modification of the chemical equilibrium between pore solution, and solid hydrates.
