Copper Flotation

A Copper Flotation Flowsheet. Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two or more …

The Extraction of Copper

This is used to make sulfuric acid via the Contact Process.

Copper Production: How Is Copper Made?

The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.

Copper-Nickel Ore Processing

Copper can be extracted, with very small amounts of nickel, at pH 6.0 to 6.5, while nickel is extracted from the copper raffinate at pH 8.0 to 8.2. These pH values refer to the pH of the aqueous phase entering solvent extraction; the corresponding equilibrium pH values are approximately 4.7 (copper) and 6.2 (nickel).
