Refining Gold Processing

2020/8/18For example, ore sorting; that's certainly been gaining more market acceptance. A lot of that is to do with the technology and the instrumentation that's available. "But something like the gravity circuits, if you think of 20 years ago, for the most part the gravity circuit was an afterthought or add-on, that wasn't really well designed and engineered for most plants.

Electric Smelting Electrolytic Refining of Lead

Lead concentrates from Kuroko (black ore) mines, which contain Cu 4 – 7%, Pb 55%, Zn 3 – 7%, As 0.5 – 0.9% are treated by hydrometallurgical process in order to smelt the product by electric furnace smelting together with other lead resources from Kuroko. The hydrometallurgical pretreatment involves sulfuric acid leaching at first stage, ferric leaching at second stage. History In 1967 Get price
