Abstract:Jintong Company adopts the process of slow cooling slag, flotation to recover copper, and magnetic separation to recover iron. After the optimization of production organization and key process control indicators and technical research, and after ensuring the effective recovery of slag and copper selection indicators, more than 50% of iron concentrates is produced, and the smelting slag and blowing slag are mixed with magnetic separation of iron concentrate. Compared with the production rate of raw ore reaching more than 35%, the tailings reduction has been greatly achieved, and the large amount of benefits have been created for the company.
