fine grinding in metallurgy

  • Metallurgy Definition, Principles & Examples

    1. Crushing and grinding: The first process in metallurgy is crushing of ores into a fine powder in a crusher or ball mill. This process is known as pulverization. 2. The concentration of ores: The process of removing impurities from ore is known as a concentration of minerals or ore dressing.
