Copper ore processing. According to the metallurgy process, the copper ore is divided into three natural types by the ratio of copper oxide and copper sulfide. That is, sulfide ore, containing less than 10% copper oxide; oxidized ore, containing more than 30% copper oxide; mixed ore, containing 10% to 30% of copper oxide.
Few of them knew organic chemistry. Those in charge of flotation rarely had flotation laboratories. Flotation research was done by 'cut and try' and empirical methods. The mining industry had no well equipped research laboratories manned by scientific teams. Froth Flotation Handbook The copper concentrate from a copper lead zinc …
For iron ore this involves crushing the ore and then concentrating it in different ways, for example by milling, flotation or magnetic separation. At some sites the ore is processed further and pelletised for use in direct reduced iron (DRI) steelmaking. In the processing stage, the mined material is transformed into usable raw material.

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 …
The concentrator was initially designed to treat 80,000 to 85,000t/d, yielding 700,000t/y of copper concentrate. Design recovery rates were 91% for copper and 70% for gold. Run-of-mine ore is handled in an 8,400t/h Svedala gyratory crusher, which feeds a coarse ore stockpile.
Every year the ore that is processed at the concentrator plant yields 269,000 tons of copper, 500,000 ounces of gold, 4 million ounces of silver and 28 million pounds of molybdenum production. Challenge. Kennecott Utah Copper operates the Bingham canyon mine concentrator plant, a smelter and a refinery.

The thickener is a very basic piece of machinery that performs its job in an easily understood manner. It simply provides a holding area large enough to allow the concentrate time to settle to the bottom. Once there, there are RAKES that rotate pulling all of the mineral to the center of the thickener. Prom that point it is pumped to the filter.
