Gold Extraction and Recovery Processes

Various methods such as gravity concentration, flotation, panning, pyrometallurgy, cyanidation etc are available for the extraction of gold metal from its ores. Amongst these methods, cyanidation is the most common method used in the leaching of gold from the ore. This process involves the dissolution of gold

Mineral processing

Overview

Mineral processing can involve four general types of unit operation comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is dictated by the grade and recovery of the final product. To do this, the mineralogy of the ore needs to be considere

Concentration of Ores Hydraulic Washing, Froth Flotation

Another method of concentration of ores is the Froth Flotation Method. This is the process for concentration of primarily sulphide ores. It has the advantage over gravity separation because it can collect even the extremely fine particles of minerals. The process uses the difference in the wetting characteristics of minerals and gangue.
