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. Additionally, higher prices can be achieved with

A single piece of gold ore generally has very little actual gold content. Although a very rich ore may have some visible gold present, the vast majority do not actually have any visible gold present, and only crushing and processing of the ore will release the gold within to host material. For example, lets say that a mine was processing ore
The lowest cost gold is normally produced by open pit mining with minimal crushing, followed by dump or heap leaching with cyanide. Gold recovery is usually around 80 , but can be as low as 60 . Recoveries can be improved to 95 99 by grinding to fairly fine particle size, gravity separation, cyanidation and flotation, all of which increase capital and operating costs. In some cases, oxidation

Gold ores are typically amenable to sensor based ore sorting to some degree, and this is usuallyplished with XRT or laser sensors, orbination of both. A two step sorting flow sheet consisting of an XRT rougher plus a laser scavenger or alternatively, a laser rougher and an XRT scavenger has already proved an optimal recovery method for a number of deposits. In quartz type gold
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.
