In the bauxite refining process, the aluminum-bearing minerals in bauxite are converted in a multiple-step process to alumina (Al2O3). Alumina can be smelted to form metallic aluminum or it can be used as the source of many other products, including refractory materials used to line high-temperature rotary kilns and metallurgical furnaces.
The Cu-Pb-Zn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage.
Smelting is a process of applying heat to ore in order to extract out a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.
Copper extraction refers to the methods used to obtaining copper from its ores.The conversion of copper consists of a series of chemical, physical, and electrochemical processes.
Lesson on separation of substances for high school chemistry experiments.
Zinc processing: Zinc processing, the extraction of zinc from its ores and the preparation of zinc metal or chemical compounds for use in various products. Zinc (Zn) is a metallic element of hexagonal close-packed (hcp) crystal structure and a density of 7.13 grams per cubic centimetre.

The Aripuanã Zinc Joint Venture Project is one of the world's tenth largest undeveloped zinc projects and covers a complete mineralized massive sulphide district, with five areas of mineralization (Arex, Ambrex, Babacu, Massaranduba and Mocoto) over a 25 kilometer strike length.

Crystals and Gemstones. Crystals-- In science, a crystal. is a solid substance in which the atoms, molecules, or ions are arranged in an orderly repeating pattern extending in all three spatial dimensions.
Processes of Ore Formation. Current theories of the genesis of ore deposit can be divided into internal (endogene) and external (exogene) or surface processes.
Because most minerals are finely disseminated and intimately associated with the gangue, they must be initially "unlocked" or "liberated" before separation can be undertaken.
Zinc and Cadmium. An opportunity to talk about Hume-Rothery rules and order-disorder transitions, as well as zinc

The most successful copper heap leaching operations have been those processing copper oxides and secondary copper sulphides ().Chalcocite (Cu 2 S) is the main copper sulphide mineral mined at bioleaching operations.

Induced Polarisation (IP) techniques are especially useful in exploration for disseminated sulphide mineralisation. The IP phenomenon is seen as a decaying voltage, lasting a few seconds,after a current transmitted into the ground is switched off.
