Jan 01, 2005 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, semi-autogenous grinding (SAG) ball-mill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses on SAG
Jan 01, 2016 Elements specific to gold ore processes, such as dry grinding for roasting operations, security considerations for gold milling, reagent additions, and integration of mineral processing steps in the comminution circuit, are also addressed

Continuous control of the final grinding product size is important to optimize gold liberation for gold milling operations. In addition, the live monitoring of the final product particle size leads to a maximum grinding circuit throughput

These percentages can be higher for ore types requiring high power input during comminution. The impact of comminution on project economics is also increasing with the observed quantum shift in the minerals

In a comminution circuit, there are four variables that influence the utilization of the power available to comminute the ore
Get PriceThis 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
