Introduction to Mineral Processing. Mineral processing is a field that contends with procedures and technologies used for separating valuable minerals from gangue or waste rock. It is a process that converts the extracted ore through mining activity into a more concentrated material, which serves as an input for the extractive metallurgy.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles ...

Gold Ore Mining. Placer gold mining mainly refers to mining from the land surface or river or underground. It mainly uses gravity separation because its density is much bigger than other minerals. Compared with placer gold, rock gold ore has higher gold content and mining value, but the beneficiation process of rock gold ore is much more complicated than that of placer gold ore.
