Concentration of the ore (ore dressing
) The removal of the undesired foreign impurities i.e., gangue, from the ore is called concentration (or beneficiation) of the ore. Either of the following methods is used for concentrating the ores..
Concentration of Ore - Ore Dressing
Concentration of Ore - Ore Dressing - Ore is a impure metal containing large amount of sand and rocky material. The impurities like sand, rocky materials, limestone, mica etc present in the ore is called gangue or matrix. The substance added flux to..
Concentration - Enrichment of Ores
Ore is an impure metal containing large amount of sand and rocky material. The impurities like sand, rocky materials, limestone, mica etc present in the ore is called gangue or matrix. These impurities must be removed from the ore before the extraction of the metal. T..

Concentration
Nitric acid can be concentrated up to 68%. It cannot be concentrated beyond this percentage by simply boiling because the aqueous solution of this concentration of nitric acid forms a constant boiling mixture at 121 o C. However, the acid can be further concentra..

Gold-containing ore gets dissolved in KCN solution in the presence of air to give a solution containing K[Au(CN) 2 ]. Gold can then be recovered from this solution by either precipitation or electrolytic method. Electrostatic concentration and liquation are other ..
Other Methods of Expressing Concentration of Solution
Molality is defined as the number of moles of solute dissolved per 1000 g (1 kg) of solvent. Molality is expressed as 'm'. Mole Fraction is the ratio of number of moles of one component to the total number of moles (solute and solvents) present in the solution. It is expressed as 'x'. ..
