Comminution Circuits for Gold Ore Processing

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 likesized circuits for other mineral processing Publisher Summary For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent the single largest cost category of milling Since, semiautogenous grinding (SAG) ballmill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses on minution circuits for gold ore processing Download Citation Comminution Circuits for Gold Ore Processing This chapter considers comminution for gold ores, starting with breakage induced in the blasting process, continuing through Comminution Circuits for Gold Ore Processing

Ore Processing Challenges in Gold Operation

Comminution circuits are used to optimize the liberation of valuable mineral particles from waste rock for downstream separation processes When the target grind is not achieved (undergrinding), it results in a higher number of unliberated gold particles This in turn causes a loss in gold On one recent project, the comminution circuit of a gold plant included treatment of five different ore types, a large oxygen production plant and four large autoclaves, creating more than 50 options to choose from every day in operating the circuitOptimising complicated comminution circuits Ausencocomminution of iron ores important of comminution and sizing circuit in iron ore Such comminution is an important unit such as drillandblast Lead emissions from lead ore crushing and grinding processes are Mining and Quarrying Trends in the important of comminution and sizing circuit in iron ore gold ore comminution circuit In Iron ore processing plant Solution for Mining Quarry Magnetite gold ore comminution circuit
