ISASMELT - Wikipedia

The ISASMELT process is an energy-efficient smelting process that was jointly developed from the 1970s to the 1990s by Mount Isa Mines Limited (a subsidiary of MIM Holdings Limited and now part of Glencore plc) and the Australian government’s Commonwealth Scientific and Industrial Research Organisation ("CSIRO") It has relatively low capital and operating costs for a smelting process...

Smelting - Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal It is a form of extractive metallurgyIt is used to extract many metals from their ores, including silver, iron, copper, and other base metalsSmelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind...
