Gold processing plant supplied by kefid machinery company have different types, as for different customers’ requirement, our gold mining and processing plant capacity are from 1 ton per hour to 200 ton per hours, usually, the small scale gold processing plant are widely chose by most our gold miner. Gold processing plants by us are optimized for the specific gold extraction requirements of the mineral deposit being processed. We?lead the field of gold processing to produce the most advanced and technically superior gold processing plants.

There are many different technics involving in gold processing application together with?gold crushing; grinding; washing; filtration; sorting; sizing; gravity concentration; magnetic separation; flotation; and agglomeration etc. According to gold ore characteristics and gangue articles, distinct technics may be used in gold processing plant.

For 100 ton per hour?gold processing plant, the necessary equipment are gold mine mining equipment, gold ore jaw crusher with 120 to 150 ton per hour, gold ore screen, gold ore grinding mill ( gold ore ball mill machine is the best choice), gold ore dressing or gold beneficiation plant. but for different type of gold, it is better to choose different types, if need more information about?gold processing plant, please contact us.

Gravity concentration or gravity separation is a common used method of separating a suspension into its individual components. Usually, the finished concentration is a ratio of the difference between the density of the heavier particle and the fluid, to the difference between the density of the lighter particle and the fluid.

Gravity separation introduce

Gravity separation is widely used in processing coal, non-ferrous metals, rare metals and precious metal ore, also used for processing asbestos, diamond and other non-metal mineral. Gravity separation usually has jig separation, chute ore dressing, table separation (table) and heavy medium separation, etc. By use of medium, gravity separation has wet re-election and dry wind re-election. In order to enhance fine grained material of separation effect, there also used centrifugal field spiral chute, centrifuge, cyclone and reelect equipment in heavy selected process. For the most effective gravity separation, particle sizes should be relatively close, with very small or very large particles screened out.

Gravity separation technology

In mineral beneficiation industry, the common process of gravity separation method including heavy medium choose, jigging, table separation, chute choose, centrifugal choose, etc. The advantage of gravity separation are low processing cost, can handle a wide range of material particle size (from 0.02mm to Hundreds of mm), less of environmental pollution and so on..

Flotation machine are popular for applications amongst the separation of ferrous and non ferrous metal for example fluorite and talc. It has an impeller which will create centrifugal forces in the form of negative pressure. In modern industry, floatation separator is widely used in chemical, construct, metallurgy, machine making, feed processing, environmental protection and ceramics.

Flotation Process that widely used by mineral ore processing industry are followings: absorption, acid-base extraction, crystallization, cyclonic separation, chromatography, cross-flow filtration, dialysis, flocculation, froth flotation, gravity separation, dissolved air flotation, distillation, drying, recrystallization, reverse osmosis, sedimentation, leaching, loiquid-liquid extraction, microfiltration, osmosis, precipitation (chemistry), solid phase extraction, sublimation, yultrafiltration and so on.

If need more information about flotation equipment, flotation process & technology, please feel free to contact with us, our engineer team can you give full support on machines choose and flotation processing plant design.

Flotation equipment used for separate different mineral, there are many types of flotation equipment can be chosed, the most used equipment are API oil-water separator, depth filter, belt filter, centrifuge, electrostatic precipitator, evaporator, filter press , protein skimmer, scrubber, spinning cone, fractionating column, mixer-settler, rotary vacuum-drum filter, sublimation apparatus and so on.

Mineral ore flotation equipment is applicable for separating non-ferrous metal, black metal, noble metal, non-metal mineral, raw body and materials of chemical industry, which are subject to coarse separation, swept separation and flotation, so the useful ore are reclaimed.

Kefid floatation machine has the advantages of large air-absorption capacity and low energy consumption. Every cell owns three functions: air absorption, slurry absorption, and floatation separation, and the cells form a floatation separation loop by itself without any auxiliary equipment, and is allocated horizontally, which favors the change of flow. The circulation of mineral slurry is reasonable, and can avoid the disposition of coarse sand to the largest extent. Floatation machine also has self-control device on the surface of mineral slurry make it easy to adjust. The impeller has backward-inclined upper and lower vanes, which produce upper and lower circulation of mineral slurry respectively.

In mineral ore grinding flotation processing, each series by a 1500 * 3000mm lattice-type ball mill with 1200mm single spiral classifier period of closed-circuit grinding,? grinding concentration of 79% to 82%, the classifier overflow concentration34% to 36%,? and the fineness of 59% to 62% -200 mesh,? a period of flotation using a rough selection,? secondary selection,? a sweeping election,? shared the 5A flotation machine 12 slot.? Stage grinding ball mill using a 1500 * 3000mm and 250mm hydrocyclone constitute a closed-circuit cyclone overflow concentration of 25% to 28%,? 90% -200 mesh fineness.? Sec flotation rougher time,? three selection,? secondary scavenger shared 5A flotation machine 16 slot.

Flotation is an important technology in mineral processing, and flotation equipment are common chosed according to different mineral process. Usually, flotation machine is applicable for the separation of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc. Flotation process also called flotation separation, which is a method of separation widely used in the wastewater treatment and mineral processing industries.

We has mentioned in above, flotation machine are popular for applications amongst the separation of ferrous and non ferrous metal for example fluorite and talc. It has an impeller which will create centrifugal forces in the form of negative pressure. In modern industry, floatation separator is widely used in chemical, construct, metallurgy, machine making, feed processing, environmental protection and ceramics.
