Dec 20, 2017 . Full-text (PDF) | Crushing and grinding of ores and their beneficiation by washing away gangue minerals has been practiced since ancient times. Primitive crushing was done by hand pounding the ore with a hard stone then by using metallic hammers. The mortar and pestle was mechanized using a lever.

mineral concentration process that is used to recover a vast array of different minerals containing valuable commodities such as copper, lead, zinc, nickel, molybdenum, tungsten, silver, gold, phosphate and potash. In the flotation process, ore is ground to a size sufficient to adequately liberate desired minerals from waste.

This paper describes studies of two relatively coarse-grained sulphide ore grinding circuits (one copper and one lead/zinc), carried out to quantify the behaviour of the liberated minerals. The work.
The test sample was obtained from Enyigba village in Ebonyi State. A reference material. (granite) was sourced from Anguwan-Boro granite deposit, Sabo, Kaduna metropolis. A known weight of reference and test material were crushed, pulverized and ground using the laboratory ball mill machine. The cell used in grinding.
