bayer method of ore concentration

Bayer process Wikipedia

The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer.Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide. The aluminium oxide must be purified before it can be refined to

Bauxite is concentrated by: Toppr Ask

The bauxite is purified by the Bayer Process. First the ore is mixed with a hot concentrated solution of sodium hydroxide. The N a O H will dissolve the oxides of aluminum and silicon but not other impurities such as iron oxides, which remains insoluble. The insoluble materials are removed by filtration.This method is called the chemical method.

Gold processing Mining and concentrating Britannica

15-09-2020· Gold processing Gold processing Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into

Concentration of Gold Ores a Key to Reducing Mercury

Simple concentration methods reduce the amount of mercury required for amalgamation to roughly 1 part mercury per 1 part of gold recovered. A vast improvement. Better yet, almost all of the mercury that is applied to a good concentrate ends up in the gold-mercury amalgam and if this mercury is recycled, for example by using a retort, losses can be further decreased by an additional 95%.
