Jan 01, 2016 In general, comminution considerations for gold milling typically do not differ substantially from those for base metal or other comminution circuits. Also, an increasing portion of gold production comes along with base metals. Many significant gold mining companies, for example, have one or more copper–gold properties in their portfolio.

Jan 01, 2005 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.

Jun 16, 2020 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 (under-grinding), it results in a higher number of unliberated gold particles. This in turn causes a loss in gold recovery and therefore revenue.

Apr 17, 2018 In a comminution circuit, there are four variables that influence the utilization of the power available to comminute the ore. Feed size Product size Resistance to breakage Feed rate Beyond these four are other factors, such as: Breakage patterns Pulp density Moisture content in the ore Clay or sticky component in the ore

As Figure 1 shows, comminution is generally the most power intensive process and generally consumes in excess of 50% of total site power. In the US mining industry, 40% of all energy consumption is estimated to be attributed to grinding, inclusive of mining (drilling, blasting, hauling) and processing [1]. Grinding power alone can account for
