Comminution Circuits for Gold Ore Processing ScienceDirect

This chapter considers comminution for gold ores, starting with breakage induced in the blasting process, continuing through primary crushing, primary milling, and secondary milling. Both technical and operational considerations are reviewed; while gold ore comminution is broadly similar to like-sized circuits for other mineral processingEconomic activities are broadly defined as any human endeavour that results in monetary gain. Primary, secondary, and tertiary activities are the basic categories into which economic activities are placed. Within the realm of tertiary activities, the higher-level services are further subdivided into quaternary and quinary activities.Sectors of the Economy: Primary, Secondary, Tertiary

Copper–gold ore processing with ion exchange and SART

Ore processing is by conventional cyanide heap leaching, which produces a pregnant leach solution (PLS) containing 1–2 ppm of gold, together with 1000 ppm or more of copper. The PLS is treated by column ion exchange, using Dow’s gold-selective MINIX resin. Loaded resin is stripped with an acidic thiourea solution, from which gold and silverCrushing is usually a dry process and carried out on ROM ore in succession of two or three stages, namely, by (1) primary, (2) secondary, and (3) tertiary crushers. 13.3.1.1 Primary Crusher.

What Is Primary, Secondary, and Tertiary Crushing?

The degree to which material is reduced through stages of primary, secondary, and tertiary crushing can depend on the type of material, like aggregate, concrete, and asphalt, and can also depend on the variety of output sizes needing produced. Primary crushing is the first stage of material reduction and can sometimes be the only
