2016-1-1 · In 1993, the Salsigne Gold Mine was reopened. Salsigne treated a gold-bearing pyrite/arsenopyrite ore by flotation, with the flotation tails treated in a CIL circuit and the concentrate reground in a conventional mill to approximately 25–30 μm. The oxygen demand for reground concentrate was high and the rate of oxidation was slow.

Gold processing 101 - Mining Magazine
2017-9-7 · 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 ...

Precious Metal Heap Leach Design and Practice - Ore-Max
2020-6-24 · Ores are typically coarse-crushed (75mm) but may show recovery of 70% or better at run-of-mine sizes. The largest of the northern Nevada heap leaches (Carlin, Goldstrike, Twin Creeks) treat this type of ore. Unoxidized ore contains gold locked in sulfides, and also contains organic (carbonaceous) components, which absorb the gold from solution.
