Concentration, dressing, or beneficiation of ores is the process of removing undesirable particles from ore. There are various steps to it. The variations in physical characteristics of the existing metal complex and that of the gangue are used to separate the needed material from the ore. Gangue is a mineral that contains undesirable elements.

Solution. The correct option is B Gold. Hydraulic washing is a technique used when the impurities are lighter and the ore particles are heavier. The lighter impurities are removed by washing in current of water. As gold particles are heavier than the impurities like sand, we can use hydraulic washing for the concentration of ores of gold.

Concentration of Ores. Ore enrichment, also referred to as concentration of ore, is the removal of gangue particles from ore to increase the number of metals in the ore. The procedure of ore concentration is a critical stage in obtaining a pure metal from its ore. An ore contains several contaminants, including sand, grit, and pebbles.
