By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations. The entire processing line can be planned in semi-mobile form and consists only of crushers, screens, belts and sorting machines. This allows immense cost savings for transport, since the waste rock is disposed of on-site.
For rock type ore, the primary processing is crushing and grinding to a suitable size that the minerals are liberated from veins and then the liberated material goes for separation stage. For placer mine, normally it needs to be sieved first to take out all big size veins and then goes for separation.

Sep 07, 2017· At current gold prices this is worth about US$600. Both smelter treatment charges and oxidation or bio-leach costs are at least $200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around 0.5. Clearly this is a function of gold price, but in the current gold price and cost ...

Flotation is one of the most widely used methods for gold ore processing. Through this method, gold can not only be enriched into sulfide mineral concentrate to the maximum extent, but also waste tailings, with low beneficiation cost. Cyanidation; It refers to the process of extracting gold with cyanide as leaching solution.
Leaching (Gold Dissolution) Once Vat is loaded with ore, is flooded with a leaching solution of a desired cyanide concentration (usually 600 to 1000 ppm) and pH between 10 to 11 at ambient operating conditions through the filter section of the floor or added to the top of the ore charge.
