The Gravity Recoverable Gold Test and Flash Flotation
Interacting flash flotation and gravity recovery is discussed. The GRG test can be used, when linked to the behaviour of gold in grinding and classification units, to predict the recovery of GRG by flash flotation. The Cadia mill in New South Wales is used as a case study of circuit design, performance and simulation.
Jig concentrators - Wikipedia
Jig concentrators are devices used mainly in the mining industry for mineral processing, to separate particles within the ore body, based on their specific gravity (relative density).. The particles would usually be of a similar size, often crushed and screened prior to being fed over the jig bed.There are many variations in design; however the basic principles are constant: The particles are ...

Ball Mills - Mineral Processing & Metallurgy
In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.
