Mineral Ore Deposits: Meaning, Origin and Types | Geology

A few nonmetallic minerals are often found associated with an ore mineral. These have to be separated from the ore before the same is processed for extraction of the metal. These associated minerals are called gangue minerals and are worthless. Quartz (SiO 2) is a common gangue mineral associated with many metallic ore minerals.

Extraction of Metals: Methods, Processes Involved ...

· Extraction of metals from their compounds is also a reduction process. Besides using carbon (coke) to reduce metal oxides to metals, sometimes displacement reactions can also be used. The highly reactive metals such as sodium, calcium, aluminum, etc. are used as reducing agents because they can displace metals of lower reactivity from their compounds.

Mineral Processing and Ore Dressing

· Mineral Processing and Ore Dressing. Before the event of ore dressing, crude ores were shipped directly to the smelters, or the refineries, with the shipper paying the freight and treatment charges. These charges varied with the type of ore and the distance from the smelter. In all cases they were many times our modem milling costs.
