Concentration of Ores: Hydraulic Washing, Froth Flotation with Examples
Concentration of Ores. An ore of a metal is an impure source, this means other than the metal it consists of many other impurities such as sand, grit, clay, rocks etc. These impurities are collectively known as gangue. Gangue is generally commercial valueless and we must separate it from the ore. This entire process is the concentration of ores ...

Concentration of Ores
Impurities such as SiO 2, iron oxides, and titanium oxide (TiO 2) are common. Heating the powdered ore with a concentrated solution of NaOH at 473–523 K and 35–36 bar pressure is used to concentrate it. Digestion is the term for this procedure. Al 2 O 3 is extracted as sodium aluminate in this manner.

Calculating Concentrations with Units and Dilutions
Example: A sample of water is found to contain 2 ppm lead. This means that for every million parts, two of them are lead. So, in a one gram sample of water, two-millionths of a gram would be lead. For aqueous solutions, the density of water is assumed to be 1.00 g/ml for these units of concentration.

Magnetic separation: This method of concentration can be applied when the gangue and the ore particles have different magnetic properties. For example, if the ore particles are magnetic in nature and if the gangue particles are non – magnetic, then a strong magnet can be brought and the magnetic ore particles can be sucked out from the powdered ore.
