belgian process for extraction of zinc. 2 Zinc can be produced by a process called froth flotation, which is also used for reduction of copper and lead or This process involves grinding the zinc ore to a fine powder, mixing it with water, pine oil, and flotation chemicals, and then agitating the mixture to "float" the zinc to the surface...
Electrowinning Copper Chemistry Tutorial
Electrowinning can be used to extract the copper from these copper oxide ores. The process for extracting copper from copper oxide ores can be summarized as: Mining : digging or blasting to obtain the ore from the surrounding rock. Crushing : mined ore is crushed into very small pieces. Grinding : crushed ore is ground into a powder ...

The Caserones Copper Mine in Chile is operated as an allJapanfunded project led by the JX Nippon Mining Metals Group. Production of refined copper by the SXEW method (30,000 t/year) began at the mine in 2013, followed by copper concentrate production (150,000 t/year) in 2014.
Mining and Extraction: Oxide Ores
The process used to treat sulfide copper ores begins at the mine site, where the copperbearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.
Copper Ore Processing Methods
· Flotation, when first introduced between 1913 and 1916, was used primarily to reduce losses of copper in the fine tailings of gravity plants. From an accessory to gravity methods, flotation very rapidly became a major process and finally, from 1923 to 1927, all but eliminated the gravity method in the treatment of lowgrade sulfide copper ores.
copper concentrate processing
Copper concentrate smelting is a large scale, intensive process consisting of four stages: sulphur in the sulphide minerals is burntoff; the metals are melted to form a matte and the waste material forms a slag; copper in the matte is electrorefined to copper metal; and the gold/silver is refined to doré.
process to extract copper from fine concentrate powder
