Grinding Machines: Types and Selection Principles
Sep 22, 2020 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.

Froth flotation is a method of separation widely used in the wastewater treatment and mineral processing industries. Air bubbles can stick to the mineral particles if they can displace water from the mineral surface which means that the mineral has to be hydrophobic.
