Extractive Metallurgy of Copper - Meaning, Method and Example

Smelting of Copper Smelting is really a metallurgical technique for extracting base metals from their ores with both the support of heat as well as a chemical reducing agent. Copper Smelting indicates that only the concentrated ore is intensely warmed up by silicon dioxide (silica), calcium carbonate (CaCO3), and air within the kiln.

Extractive Metallurgy of Copper - Meaning, Method and Example

The most common ore used in the copper extraction is Chalcopyrite (CuFeS 2), also recognized as Copper Pyrites and other such sulfides. The proportion of copper in the real ore is too limited for straightforward copper extraction to be feasible. The concentration of ore is required, and the Froth Flotation method is used for this process.

Froth flotation - Wikipedia

Froth flotation cells to concentrate copper and nickel sulfide minerals, Falconbridge, Ontario. Froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents. The selective

Extractive Metallurgy of Copper ScienceDirect

Copper is most commonly present in the earth's crust as coppereironesulfide and copper sulfide minerals, such as chalcopyrite (CuFeS 2) and chalcocite (Cu 2 S). The concentration of these minerals in an ore body is low. Typical copper ores contain from 0.5% Cu to 1 or 2% Cu. Pure copper metal is mostly produced from these ores by concentration, smelting, and refining.

60 Centuries of Copper: The Flotation Process

The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the metal in finely disseminated particles which aggregate ...

Flotation is the conventional method for processing porphyry copper deposits, one of the most economically important sources of copper (Cu) worldwide. The rapidly decreasing grade of this type of Cu ore in recent years, however, presents serious problems with fine particle recovery using conventional flotation circuits. This low recovery could be attributed to the low collision efficiency of ...
