What is Gold Ore worth? High Grade Mining Ore
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
Gold processing 101 Mining Magazine
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.
Use ore sorting equipment to concentrate ores and cut
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
