Gravity Concentration Of Gold Bearing Ashes

Gravity Concentration Of Gold Bearing Ashes

Gold Bearing Ashes Gravity Concentration

Gravity Concentration is sorted using the relative density between the mineral particles, particle size, shape and the difference in the different media (water, air, or other relatively high density liquid) in the rate and direction of movement, so that separate from each other beneficiation . Gravity Concentration is widely used in the processing of coal, nonferrous metals, precious metals, precious metal ore, also used for asbestos, diamond and other non-metallic mineral processing. In order to enhance the separation efficiency of gold in Gravity Concentration also uses centrifugal force field spiral chute, centrifuges, cyclones and other Gravity Concentration equipment.

Gravity Concentration Advantages

In certain media or media stream (mostly Ashes), according to the proportion of the difference an election particles of mineral raw materials other processes. Mainly used for sorting useful minerals and gangue minerals have a greater proportion of poor materials, such as tungsten, tin and gold and so on. For Gold Bearing Ashes, Gravity Concentration is the most important election of gold methods. The advantages are:

  • 1. Low production costs.
  • 2. Material can handle a wide particle size range, up to several hundred millimeters thick, a thin up to 0.02mm.
  • 3. Less environmental pollution, the product easy to dehydration. But for less than 0.1mm and 0.5mm gold ore, mineral processing equipment efficiency and capacity are low.

Gold Bearing Ashes Gravity Concentration

Gold Bearing Ashes using heap leaching – Chute Gravity Concentration- cyanidation CIL gold recovery process, using the process in line with the nature of Gold Bearing Ashes ore, reflecting the principle can receive early harvest, made a very good technical and economic indicators. Technology exists is insufficient, Gravity Concentration using a fixed chute roughing – artificial panning selection method, not only labor-intensive, and Gravity Concentration recovery of only 6% to 8%, which led to some coarse grained gold heap leach into the or CIL jobs. Despite the heap leach (CIL) initial high concentration of cyanide leaching, and other measures to extend the leaching time, but the high grade tailings situation sometimes occurs, even with the ore grade is almost the same, indicating that leaching time can not meet this part of the coarse grained the need for gold leaching. On the other hand will inevitably lead to high concentrations of cyanide leach cyanide dosage increases, increased production costs.
