hypothesis of copper ore dressing

MINING

Copper processing - Ores Britannica

In the ore-dressing plant, the material received from the mine is crushed in several stages and finely ground to a size which ensures that copper minerals are liberated from the waste materials, or gangue. In cases where the next step is leaching most frequently in the case of oxide ores , complete liberation of the copper minerals is not always necessary; the ore needs to be crushed and ground …

In this machine the Seven Trust ore, after calcination was fed onto a moving belt which passed underneath two pairs of electromagnets under which further belts ran at right angles to the feed belt. The first pair of electromagnets was weakly magnetised and served to draw off any iron ore present. The second pair were strongly magnetised and attracted the wolframite, which is weakly magnetic. These …

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..

Copper ore was spalled in the same way as with tin.

Copper oxides are unusual in two respects. First, octahedral-site Cu II : t 6 e 3 contains a single e hole in the 3d shell, which makes it orbitally degenerate and therefore a strong Jahn–Teller ion; consequently, Cu II ions normally occupy octahedral sites that are deformed to tetragonal c/a > 1 symmetry by Jahn–Teller orbital ordering. However, in the absence of a cooperativity that ...
