Gold extraction QueensMineDesignWiki

A 20Mt/a mill will have a capital cost within $10,000 /t/h and $20,000 /t/h (Lane, Fleay, Reynolds, & La Brooy, 2002). Typical operating costs for mills used in gold extraction are summarized in Table 3. The selection of a mill size is ultimately a function of the economics of the project and which mill size will maximize the project NPV.

IsaMill Wikipedia

The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
