mineral processing flowsheets

The Mineral Processing Flowsheets shown on the following pages are based on actual data obtained from successful operating plants. Metallurgical data are shown in these flowsheets which incorporate Crushers, Grinding Mills, Flotation Machines, Unit Flotation Cells, and Selective Mineral Jigs as well as other standard milling equipment.

The Flotation Machine, the Selective Mineral Jig and the Unit Flotation Cell have revolutionized flowsheet design and have made it possible for both small and large plants to increase recoveries and economical return.The Unit Flotation Cell and the Selective Mineral Jig have been perfected to meet the most important principle in ore dressing.

To recover this free mineral, either the Unit Flotation Cell or Jig or both can be installed in the grinding circuit without auxiliary equipment such as pumps or elevators, and for successful operation do not usually require more water than necessary for classifier dilution.

Many of the flowsheets given here have been made possible because of the fact that a coarse pulp (particles as coarse as 1/4)can be circulated in the Sub-A Flotation Machine without sanding or choke-ups and with high metallurgical efficiency.

Sub-A Flotation Machines have the gravity flow principle and flexibility that has made possible the development and application of many of these flowsheets. In fact, the elimination of pumps in handling concentrates for cleaning and recleaning has simplified flowsheets and reduced operating expenses to the operators advantage and profit. It should be pointed out that it is not only the cost of pump wearing parts but the time lost in shut-down for pump repair that is important in profitable mill operation.

Ore Testing takes the guesswork out of answering the question of can this ore be milled profitably. It also gives conclusive answers to the subordinate- questions of what type of flowsheet will give the greatest net return on this operation, and can increased value and/or increased mill capacity be obtained by the addition or substitution of equipment in the mill?

In other words, ore testing is the key to the basic question of the economic possibility of a mining operation. It gives the answer to this question at a minimum of expense without making a costly investment in equipment to learn it the hard way.

The results obtained through ore testing and the intelligent interpretation of the results very often lead to a simple method of treatment giving good profits, where some other treatment might mean less profit or an actual deficit. Our Labgives a good illustration of what proper selection of treatment methods based on ore testing can result in. Test results give you facts.

The 911MPEProcess Equipment Ore Testing Laboratory is continually being confronted with and solving such problems. Very often situations arise where the most common methods of treatment may not be successful but little known and ingenious methods may be applied. The flowsheet showed the results obtained from testing a complex lead-zinc-copper-iron ore containing values in gold. Exceptionally high grade and recovery were obtained in this instance. Utilizing a patented process special reagents made profitable production of lead/copper and zinc-iron concentrates and subsequent separation of these concentrates into four (4) separate products.

Although flotation has made profitable the bene-ficiation of many low grade ores both metallic and non-metallic, it is not always true that flotation will give the greatest economic retiirn. For instance, in many cases, cyanidation of gold ores either direct or as part of a composite method of treatment may be the answer to the question of, what treatment will give the greatest dollar value return on the mill investment ?

An ore sample was received at the 911MPEEquipment Laboratory of a character which would ordinarily respond to the counter-current decantation method of cyanidation for extracting gold. Samples of the Same ore gave results concurring with test work by others but this method was not recommended due to settling difficulties encountered.

Work was not stopped here, however. Eventually, a successful method for treating this ore was found by sacrificing a small loss in slime. The final flowsheet evolved with recoveries indicated which made profitable installation of a reasonable cost plant, overcoming the difficulty arising from the physical characteristics of the ore.

Change of reagents in a flotation circuit may give higher recovery, a better grade of concentrates or both. A Sub-A Unit Flotation Cell installed in the grinding circuit may permit an increase in tonnage milled, a decreased loss in slimes and a better overall recovery.

AMineral Jigs installed in the grinding circuit in cyanide mills have proved very successful in increasing recovery. It is always advisable to recover your mineral values as soon and as coarse as possible.

Typical flowsheets are shown for both metallics and non-metallics as well as industrial products, wastes, etc. De-inking of waste paper by flotation, for example, is coming into prominence with Flotation Cells as it is now possible to recover for the paper industry a useful and usable product on a much more attractive basis than in the past.

Your flowsheet should be designed without bottlenecks or weak links which present problems that can seriously effect operating efficiency. The old saying of one hours delay means no profit today is more true today than ever before due to higher operating costs. This adage emphasizes the importance of having your flowsheet designed efficiently and tailored for your specific operation, and the need for selecting standard reliable equipment designed to give you continuous service.

tin mining, tinning process, extraction of tin, tin mining process - xinhai

[Introduction]: The density of tin ore is larger than the paragenetic mineral, so the mining process of tin ore is gravity separation. However, all kinds of iron oxides exist in those ore, like magnetite, hematite, etc., which cannot be well separated by using gravity or flotation separation. Herein, magnetic separation and flotation separation will be used.

[Application]: Gravity separation is the traditional method for tungsten, tin and gold, especially placer gold and placer tin. It is also common in the application of rare metal placer ores(niobium, tantalum, titanium, zirconium and so on). It is also used for weak magnetic iron ore, manganese ore and chrome ore.

Put the 20~4mm ore into heavy medium cyclone to be selected. Then the ore will enter into the rod mill. After that, it will be preselected in jig. The tailings over 2mm will be abandoned, and the ore below 2mm will be put into shaking table.

After the bulk flotation, the concentrate will be fine grinded, then will be do the flotation separation of lead zinc ore. After that Lead antimony concentrates and zinc concentrates will be produced.

The tin pulp enter into 300mm hydrocyclone, then overflow to 125mm and 75mm hydrocyclone group to remove the fine mud. The sand setting will enter into the process of thickening, desulphurization by flotation, and then cassiterite flotation.

talc mining | processing equipment | flow chart | cases - jxsc

The term talc refers both to the pure mineral and a wide variety of soft, talc-containing rocks that are mined and utilized for a variety of applications. Talc forms mica-like flakes. Talc is the softest mineral on the Mohs hardness scale at 1 and can be easily cut and crushed. Talc has perfect cleavage in one direction. This means that it breaks into thin sheets. As a result, it feels greasy to the touch (which is why talc is used as a lubricant).

Most talc is mined today by conventional open-pit, drill-and-blast, shovel-and-truck techniques. The major difference from conventional technology is that blasting is minimized to reduce breakage of soft talc ore.

Most talc in the United States is produced from an open pit mine where the rock is drilled, blasted, and partially crushed in the mining operation. The highest grade ores are produced by selective mining and sorting operations.

Great care is taken during the mining process to avoid contaminating the talc with other rock materials. These other materials can have an adverse effect on the color of the product. Contamination can introduce hard particles that cause problems in applications where talc is being used because of its softness or lubricating properties.

Partially crushed rock is taken from the mine to a mill, where it is further reduced in particle size. Impurities are sometimes removed by froth flotation or mechanical processing. The mills produce crushed or finely ground talc that meets customer requirements for particle size, brightness, composition, and other properties.
