A video of mining and mineral processing may be seen in The Mining Process at Copper Mountain Mine. This mine produces 30,000 tonnes of ore and 160,000 tonnes of waste rock per day. ... A typical process flow diagram of copper ore beneficiation. The multimetal copper-zinc-lead ore is treated by integration of three complete banks in series ...
The smelting process involves heating and melting ore to extract metal. Refining refers to any process increasing the grade or purity of the metal. The result of the refining process for copper production is copper cathode, which is generally 99.9 percent pure. The figures below represent global production and trade of refined copper (ICSG, 2015).
Concentrator Operations. The ores received into the plant, after conventional washing, crushing and grinding, are subjected to differential flotation for the recovery of sulphide copper mineral for smelting and oxide (or non-sulphide) copper minerals for leaching. Sources of feed materials to the concentrator are: (a) Nchanga …
Mixing Flotation Process: The mixing flotation process is to separate nickel ore in which copper has lower content than Nickel, the mixed concentrate of copper and nickel will smelt into high-grade nickel directly.
