#0183;#32;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 circuit.
#0183;#32;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 SAG.
#0183;#32;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 coppergold properties in their portfolio.
Approximately 9M and 120M is expended on the comminution circuit (crushing, stockpiling and grinding) representing 35% and 50% of plant capital cost for the 1 Mt/a and 20 Mt/a plants, respectively. Comminution costs include power, grinding media and maintenance materials.

The 366 Mt Telfer mine reserve consists of a diverse range of copper and gold mineralisation, from massive sulphide reef ores to stockwork ore, oxide copper minerals to chalcopyrite, siltstone to competent quartzite, all with relatively high levels of gravity recoverable gold. The complexity of the orebody demanded a flexible
around 20% of direct operating costs in a typical gold plant, inclusive of salaries, wages, fuel, reagents, wear parts, and maintenance. 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
#0183;#32;The resultant product will pass through comminution circuit, which includes gravity gold extraction, followed by CIL and carbon elution circuits. Infrastructure at Yandal The Yandal project has existing infrastructure such as a 240person mining camp, operational airstrip, power, water and telecommunication infrastructure, and a network of haulage and access roads.
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
The ore is first reduced in size (typically 80% passing 75#181;m) to ensure that all non refractory gold is readily accessible for cyanide leaching. There are several variations of comminution circuits used in the gold industry, such as: Multistage crushing and pebble and/or ball
Comminution Circuit. (COS) located at the plant facility. The COS has a live capacity of 40,000 tonnes and a total capacity of nearly 400,000 tonnes, when bulldozed to the side. Concentrator and Gold Recovery Circuits.
