Malachite - Wikipedia

Malachite is a copper carbonate hydroxide mineral, with the formula Cu 2 CO 3 (OH) 2.This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation.

Pyrometallurgical recovery of copper from slag material ...

Copper oxide reacts with the carbon reductant according to the equation: 4Cu 2 O (1) + C (s) 4Cu (1) + CO 2 (g) (5) The copper content of the slag has been found to vary with the magnetite content. By reducing the magnetite content to about 13 percent or less, the copper content of the slag can be reduced to about 1 percent or less.

Metallurgy - Wikipedia

Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are called alloys.Metallurgy encompasses both the science and the technology of metals; that is, the way in which science is applied to the production of metals, and the engineering of metal components used ...
