EPA 530 R 94 013 NTIS PB94 170 305 TECHNICAL RESOURCE UMENT EXTRACTION AND BENEFICIATION OF ORES AND MINERALS VOLUME 2 GOLD August 1994 U.S. Environmental Protection Agency
The practice of gold minerals beneficiation is optimized by using the information obtained from applied mineralogy. In this way, at the moment of development and select a process for treatment a gold ore, try to identify the gold minerals is the first step. Obviously, the detection of non valuable minerals is important.
Applied material: magnetite, pyrrhotite, calcined ore, ilmenite, etc. Gravity Separation Process. Gravity beneficiation is separating mineral according to the specific gravity of the material. Spiral chute, spiral classifier and shaking table are usually used. Applied material: gold ore, manganese ore, alluvial gold.
The ore in Inner since excessive addition of lime the gold leaching rate by 5% to 10%; a Shandong ore Again, a certain period due to insufficient amount of addition of lime, sodium cyanide consumption multiplied by 4. 82kg / t Increase to 9. 20kg / t and so on.
The gold ore grinding equipment in the grinding stage: ball mill,rod mill. . Beneficiation stage The beneficiation stage is a crucial part of gold extraction during the whole gold ore processing plant. Placer gold mine and rock gold mine are most widely processed to extract gold concentration.
A gold beneficiation process, the process uses two and a half of a closed circuit crushing, two stage two closed circuit grinding and flotation and then by selection, selection of its tailings swept away by a rough sorting operations, will be selected tailings and sweep the election together combined ore concentrate regrinding, the high efficiency of this process broken, broken fine level ...
