JXSC gold mining solutions design allows you to start recovering minerals with a base wash plant (scrubber / concentrator) unit. Various crushing, milling equipment can be ordered to make your solution more comprehensive. This can be implemented at a later stage, once you have begun to see an initial return on investment. This way, JXSC provides miners with a low capital starting point. The income that these base plants generate can then be used to fund their further expansion and enhance recovery.
This arrangement and flowsheet of a Mini Portable Gold Processing Plant permits several mineral separations by flotation and provides for the possible recovery of other minerals by gravity concentration. The flowsheet is ideal for a pilot-plant in field testing of ores to determine the economic feasibility of an ore deposit prior to the installation of a larger plant or for processing ore during the development stages of a mining property.
The arrangement shown here features the economy type rubber-lined Grinding Mill. This mill is roller-mounted with V-belt drive around the mill shell, driven from motor-connected gear reducer. Material discharged from the grindingmill is sized through a spiral screen ahead of a Cyclone Classifier. The flotation cells handling initial feed are equipped with patented discharge cones for return and recovery of a heavy mineral fraction by a jig.Tailings from the flotation machines are fed to a #6 Concentrating Table to assure gravity recovery of any valuable mineral not amenable to flotation. Pan Filters are provided to de-water concentrates.
One of the most serious problems confronting the mining industry today is how to profitably begin the small scale milling of ores from mines where insufficient ore has been developed to warrant an expensive mill installation, but where a large plant might be needed later. The same question arises in connection with the economical working of numerous small but relatively high grade ore deposits.
Portable Mills, and in particular, Truck Mills, are a most practical solution to this problem. For a relatively small investment a complete and efficient mill can be brought to the mine and speedily put into operation. When the high grade deposit has been worked or the formerly promising operation no longer fulfills the operators expectations, the mill may be transported as a complete unit to another location.
In the Truck Mill the portability has been carried out to the highest degree. All of the units are carried on a truck or semi-trailer, which serves as the operating floor for most of the units. Power for the entire milling unit is usually supplied with either a Diesel or gasoline driven electric generating set, but a belt driven mill can be supplied.
The gold mining equipment includes: jaw crusher, hammer crusher, roller crusher, impact crusher, vertical crusher, cone crusher, ball mill, vibrating screen, spiral separator, flotation machine, mining agitation tank, ore feeder, concentrator, mine hoist, mining conveyor belt, pre-watering into a ball plate, spiral chute, beneficiation shaker, washing machine and other equipment.
After the first stage crushing process, the ore material enters the double-layer vibrating screen, the crushed upper layer material with middle layer material enters the second crushing stage, the outlet material from the first crushing stage and the second crushing stage into the screening procedure. The screened material is ground by the first stage ball mill, a closed circuit grinding system is composed of the ball mill and the classifier. The staged overflow is classified by the cyclone and then enters the second-stage ball mill for re-grinding, and then forms a closed-circuit grinding with the cyclone. The gold-plating equipment cyclone overflow firstly performs preferential flotation, and the foam products are subjected to secondary selection and a three-time selection to become concentrate products. After the preferential flotation, the tailings undergo a rough selection, a selection, and two The selection process of three selections, three selections, and one sweeping, one selected tailings and one sweeping foam product enter the cyclone for re-classification, re-selection, secondary selection and one fine The selection constitutes a closed-circuit selection, and the three selections and the second selection constitute a closed-circuit selection.
Gravity beneficiation is an ore dressing method which according to mineral density and plays an important role in contemporary mineral processing methods. The gravity separation equipment includes spiral chutes, shaker tables, jigs and short cone cyclones.
1. Mercury amalgamation-gravity separation This process involves gravity separation and then mercury amalgamation or mercury amalgamation before gravity separation. The former method is mostly used for the placer gold which with low gold content, or the surface contaminated ore. The latter is mostly used for the quartz vein gold-bearing sulfide ore. 2. Gravity separation (amalgamation)-cyanide process This gold processing method is suited for the quartz vein type gold-bearing oxidized ore which with uneven disseminated grain size and high oxidation degree, the gold-bearing ore basically free of copper, arsenic, antimony, etc. 3. Flotation process This processing method is suitable for the quartz vein gold-bearing ore, gold-bearing altered rock type ore and sulfides ore which with fine gold particle and good floatability, widely applied in the medium-large good mining plant. 4. Gravity separation (amalgamation)-flotation process This procedure is applicable to the uneven disseminated grain size and low sulfur quartz veins containing gold ore. Since the monomer-dissociated gold is recovered in a timely and early manner in the grinding circuit, the total recovery of gold can be increased. This process is a widely used process in China's gold plant, in which the recovery rate of gold can reach 30-60%. 5. Cyanidation (full mud cyanidation) process Applicable to gold with a higher emerald grain size, a deeper iron ore-bearing pyrite quartz vein type ore, or a gold-altered diorite-type ore. The ore is required to contain no elements harmful to cyanidation such as copper, arsenic or antimony. 6. Flotation-Cyanide Process This process is suitable for the treatment of gold-bearing iron ore quartz vein ore with gold and sulfide symbiosis. It is also suitable for gold-bearing granite fracture zone altered rock type ore, especially for high sulfur ore. To apply. This process is also one of the common processes in China's gold mines. 7. Flotation-baking-cyanide combined process This procedure is applicable to gold-bearing quartz vein type ores containing elements such as arsenic and antimony. The roasting process is a preparation for cyanidation in order to remove elements that are harmful to cyanidation.

The Cole Springs Camp is a gold mine and mill located in the Repbulic Mining District of Nevada. The mine is noted for gold recovery from quartz veins which cut altered lava and rhyolite. The gold recovered is reported to be native, or free-milling, and was efficient to process with a simple gravity mill using crushers and shakers.
There are at least 4 open shafts on the property and 3 adits which have mostly sloughed and are in need of being dug out and secured. The mines feed an old mill that is in excellent condition and looks to have been in use in the 1970s. It will need extensive rehabilitation to be functional again but is estimated to be a 25 ton per day operation. The last suggested operation of the property is 1990 as taken from old newspapers on the claim.
There is also housing and workshops on the claim which has been inhabited recently and could be utilized as a part of the mining operation. This would allow miners to work the site at least 5 days a week and still be comfortable and sheltered.
The primary haulage portal on the property is a timbered single compartment shaft which descends an undetermined depth. There is water piping and air ventilation leading into the mine indicating some substantial size. A short distance away, a clean manway shaft is cut on a quartz outcrop and is estimated to lead to the same workings. The timber work on this main portal section is intact and appears stable, but rope and other precautions should be taken prior to entering the workings.
The other adits, shafts, and cuts are in poor condition and will need rehabilitation before entering. There is a tailings dump of roughly 10k tons below the mill. There are at least 5 waste dump piles around the property totaling an estimated 40k tons. Both the dumps and the tailings were sampled and assayed by surveyors and valuations are reported further on in this report.
The Cole Springs Gold Mine is rare in the fact that the mining camp and mill have been left nearly untouched. The property contains an intact and very usable cabin. There is also a water tank, a bunkhouse, a workshop, an outhouse, a mill, and an old forge. All of which have been maintained up until 1990 or so, and are in excellent repair.
The mines in the camp have been worked for gold. There is a documented gold trend that the mines have been cut on. It is apparent that the mines have been consistently worked, at a minimum by small miners, since the 1920s. Native gold appears on quartz with iron and iron staining.
Mines appear to be quite substantial along epithermal veins through the western slope of the mountain. The mill shows some equipment for gold processing and will need rehabilitation and a few pieces added to be functional.
As fully intact and functional gold mine, mill and housing as can be found. This site is very close to turnkey and ready to go. It is vital that the owner/operator of the claim file a notice of operation. This will allow the claim owner to take control of and utilize/repair the mine buildings. Buildings do not appear to have been touched since they were left. Only in need of slight cleanup and repair to be inhabitable. Very much a one of a kind unmolested site.
There is excellent road access to the claim and most any high clearance 4WD should be able to drive directly up to the buildings and the mines. There is parking and staging and room for multiple vehicles on multiple levels.
This is ideal for a small company or group of miners who can afford to post a Plan of Operations. The gold in the mines could be high graded while raising capital for expansion of the mines. This is not a good spot for a single miner or a casual use operation.

Based on abundant experiences on gold mining project, Prominer helps clients to get higher yield & recovery rate with lower running cost and pays more attention on environmental protection. Prominer supplies customized solution for different types of gold ore. General processing technologies for gold ore are summarized as below:
For alluvial gold, also called sand gold, gravel gold, placer gold or river gold, gravity separation is suitable. This type of gold contains mainly free gold blended with the sand. Under this circumstance, the technology is to wash away the mud and sieve out the big size stone first with the trommel screen, and then using centrifugal concentrator, shaking table as well as gold carpet to separate the free gold from the stone sands.
CIL is mainly for processing the oxide type gold ore if the recovery rate is not high or much gold is still left by using otation and/ or gravity circuits. Slurry, containing uncovered gold from primary circuits, is pumped directly to the thickener to adjust the slurry density. Then it is pumped to leaching plant and dissolved in aerated sodium cyanide solution. The solubilized gold is simultaneously adsorbed directly into coarse granules of activated carbon, and it is called Carbon-In-Leaching process (CIL).
Heap leaching is always the first choice to process low grade ore easy to leaching. Based on the leaching test, the gold ore will be crushed to the determined particle size and then sent to the dump area. If the content of clay and solid is high, to improve the leaching efficiency, the agglomeration shall be considered. By using the cement, lime and cyanide solution, the small particles would be stuck to big lumps. It makes the cyanide solution much easier penetrating and heap more stable. After sufficient leaching, the pregnant solution will be pumped to the carbon adsorption column for catching the free gold. The barren liquid will be pumped to the cyanide solution pond for recycle usage.
The loaded carbon is treated at high temperature to elute the adsorbed gold into the solution once again. The gold-rich eluate is fed into an electrowinning circuit where gold and other metals are plated onto cathodes of steel wool. The loaded steel wool is pretreated by calcination before mixing with uxes and melting. Finally, the melt is poured into a cascade of molds where gold is separated from the slag to gold bullion.
