    The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out.Sep 15, 2016 Determine the Proper Grind Size for Gold Ore. Without mineralogy, estimating the optimum Grind Size for Gold Ore Sample is most conveniently made by Laboratory Testing and the agitation leaching method, and it will be necessary to make up 3 or 4 bottle charges in order to have enough ore* for the subsequent screen analysis.

    G. Desch nes, in Gold Ore Processing (Second Edition), 2016 4.4 Ultrafine Pyrrhotite Concentrate. Ultrafine grinding is used to liberate gold finely disseminated in metallic sulfides. KCGM is the first gold mine using ultrafine grinding followed by cyanidation (Ellis and Gao, 2002).The gold sulfide concentrate is grind with an IsaMill to a P 80 of 10–12 μm.Jaw and gyratory crushers are used for initial size reduction to convert big rocks into small stones. This is generally followed by a cone crusher. A combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh (45 μm). Instead of grinding the ore dry, slurry is used as feed for rod or ball mills, to avoid dusting.

    Crushed ore is reclaimed from the bin via two belt feeders that feed to a milling circuit. This circuit has recently been upgraded from a single-stage SAG milling circuit, incorporating closed circuit pebble crushing, to now incorporate a secondary ball milling stage. This allows increased throughput, and finer grind size (higher gold recovery).Jul 08, 2016 The calculated power input or horsepower in the above example is 316. Therefore, a 350-hp motor is required and this in turn indicates that an 812 (8′ x 12′) Rod Mill is required. In the same way Fig. 3 indicates that an 800-hp motor and a 10 1/2 14 or 10.5′ by 14′ Ball Mill is required.
