Question

Quizplus · Accepted Answer

The process that selectively extracts a metal from its ore by dissolving it is called leaching. Leaching involves the use of a solvent (such as acid or alkali) to dissolve the desired metal from the ore. The resulting solution containing the metal can then be further processed to obtain the pure metal. Roasting involves heating the ore to a high temperature to drive off unwanted impurities, while smelting involves melting the ore to extract the metal. Flotation is a process used to separate minerals based on their differences in surface properties, and hydration involves the addition of water to a substance.
