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.

Recovery of metal values from copper slags by flotation ...

The recovery of copper and cobalt from ancient copper slags from the Küre region of Turkey was investigated. A fayalitic-type of ancient copper slag containing 1.24% Cu, 0.53% Co and 53.16% Fe were subjected to an experimental study. Two different routes were followed to recover the metal values. The first route was roasting the slag with pyrite followed by leaching.

Copper extraction - Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

copper extraction and purification - chemguide

In the copper(I) sulphide, the copper is +1 and the sulphur -2. The oxidation states of the elements oxygen (in the gas) and copper (in the metal) are 0. In sulphur dioxide, the oxygen has an oxidation state of -2 and the sulphur +4. That means that both the copper and the oxygen have been reduced (decrease in oxidation state).
