It is performed in cylindrical steel vessels that contain a charge of loose crushing bodies—the grinding medium—which is free to move inside the mill, thus comminuting the ore particles. According to the ways by which motion is imparted to the charge, grinding mills are generally classified into two types: tumbling mills and stirred mills .

23.2: Principles of Extractive Metallurgy - Chemistry LibreTexts

Aug 25, 2020 · First ores must be concentrated and separated from their earthly impurities. Concentration of ores may be achieved by froth flotation in which an ore is contained in a froth that floats at the top of a water vat. After the ore has been concentrated it must be roasted to a high temperature allowing for the desired metal to be oxidized.

Grinding Machines: Types and Selection Principles

Grinding machine has been widely used in gold mines in South Africa since 1905. At that time, the grinding machine used river pebble as the grinding medium, which was essentially a gravel mill. Later, in order to improve the production capacity of the mill, cast iron balls were used as the medium, so normal gravel mills were evolved into ball mills and rod mills.

Ball mill - Wikipedia

Key properties of grinding media are size, density, hardness, and composition. Size: The smaller the media particles, the smaller the particle size of the final product. The grinding media particles should be substantially larger than the largest pieces of material to be ground. Density: The media should be denser than the material being ground.
