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 ...

Extractive Metallurgy of Copper - Meaning, Method and …
The most common ore used in 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.

copper processing - Roasting, smelting, and converting
Iron and sulfur are converted to oxides and are removed in either the gas stream or the slag (the latter being recycled for the recovery of remaining values), leaving a " blister" copper containing between 98.5 and 99.5 percent copper and up to 0.8 percent oxygen. The converter is rotated for skimming the slag and pouring the blister copper.
