What is mechanical treatment of ores in metallurgy?

Mechanical treatment of ores in Metallurgy refers to the physical processes used to separate valuable minerals from waste material or gangue. This includes techniques such as crushing, grinding, screening, and classification, which help to liberate the ore particles. The goal is to enhance the concentration of the desired minerals before further processing, such as smelting or chemical extraction. Effective mechanical treatment increases the efficiency and cost-effectiveness of subsequent metallurgical operations.
