Concentration of Ores – Study Material for IIT JEE .

By flowing the powdered ore in a current of water, the lighter rocky impurities can be washed away and the ore particles are left behind. For this, either table or Hydraulic classifier is used. Generally oxide and carbonate ores are concentrated by this method. i.e. haematite and cerussite. There are two gravity concentration methods.

Copper extraction - Wikipedia

However, as the concentration of copper in the ore bodies decreased, the energy costs of smelting the whole ore also became prohibitive, and it became necessary to concentrate the ores first. Initial concentration techniques included hand-sorting and gravity concentration. They resulted in high losses of copper.

The Density of Common Rocks and Minerals

The Density of Common Rocks and Minerals

Jan 23, 2020 · The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3).
