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 processing ...Comminution circuits for gold ore processing - ScienceDirectPublisher 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 egory of milling. Since, semi-autogenous grinding SAG ball-mill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses on SAG.Comminution circuits for gold ore processing - ResearchGateDownload Citation Comminution circuits for gold ore processing For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent ...
