The present invention is a process to recover precious metals from sulfide ores. It involves chlorinating a mixture of an ore concentrate and salt to form a liquid melt. The salt preferably contains potassium chloride. This chlorination is carried out at a temperature between 300° and 600° C. while stirring. The process converts precious metals in the elemental and sulfide forms into ...

12.6 Primary Lead Smelting 12.6.1 General15 Lead is found naturally as a sulfide ore containing small amounts of copper, iron, zinc, precious metals, and other trace elements. The lead in this ore, typically after being concentrated at or near the mine (see Section 12.18), is processed into metallurgical lead at 4 facilities in the U. S.

Jul 29, 2020· Kolkata: Supply chain disruptions have lead to an over 40% rise in global copper prices and a recovery in demand in CY2021 will be linked to pandemic control and normalcy, a research note on the copper sector has said. In particular, mining restrictions due to the pandemic is estimated to have resulted in a sharp drop in production of copper ore during Q2 of calendar year (CY) 2020.

Today, A. ferrooxidans is most extensively characterized and commercially used for bioleaching [].Since 1970s, the number of microorganisms that is involved in metals sulfide oxidation has ...

The lead vanadate minerals are also developed abundantly along the edges of the oxidized base-metal ore bodies, cavity walls, and partly replace the supergene base-metal minerals. They coat the surfaces of cavities and breccia fragments, also fill fissures, fractures, and karstic conduits [ 22, 25, 28 ].
