Flotation Behavior Of Complex Sulfide Ores In The Presence. Jan 01 2017018332Base metals such as copper lead and zinc are mainly extracted from sulfide ores Mostly these base metals tend to exist together in an ore Flotation process is widely used to separate these minerals in sulfide ores 1 A wide range of chemical reagents are used in the flotation process to separate the different minerals.
09-07-2019· 1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.

Ore Concentration by Froth Flotation. Remember that only 0.67% of the ore is copper. The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and …
09-07-2019· The floatability of common copper sulfide minerals is reduced in the following order: chalcopyrite > covellite > bornite > chalcopyrite. (4) The floatability of copper sulfide minerals is also affected by factors such as crystal grain size, grain size, etc. fine grain is not easy to float.
Flotation Of A Copper Sulphide Ore From Okiep Using. This paper investigates the effects of thiol collectors xanthates dithiophosphates dithiocarbamates and mixtures of these on the froth flotation performance obtained with a bornite-rich copper sulphide ore from Okiep Copper Mine with a feed grade of 1.8 copper.

Flotation of non-sulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper recovery, for example, heap leaching. In Zambia and Zaire, however, siliceous copper oxide ores are floated with fatty acid collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated ...
Flotation Chalcopyrite from the ore ground to —150 mesh is best concentrated by the flotation pro-cess, by depressing gangue minerals like quartz, feldspar, calcite and pyrite and floating the copper mineral using a xanthate as collector. 500 gms of the ground ore obtained by coning and quartering was subjected to froth flotation
Oxidic ore can be concentrated using flotation or, if it has a low acid demand, it may be economic to acid heap leach the stockpile. The recovery of these copper minerals by flotation or...

01-10-2019· Flotation: Froth flotation is a standard technique for concentrating copper sulphide minerals from ores. The surfaces of the copper bearing minerals are made selectively hydrophobic with chemical action and collected in the froth, which is continually removed, from the flotation tanks.
Copper-nickel ore from INCO mines, Sudbury, Ontario, Canada was used in the experiments. The approximate ore composition was pentlandite 4-5%, chalcopyrite 4-5% and pyrrhotite 30-35%. The ore was ground in a polyurethane lined rod mill with stainless steel charge to avoid any external iron getting into the flotation system.
