In Fig. 1 C, grinding iron ore only produced the finest fraction, followed by the 25 % quartz and 75 % iron ore ratio, equal quantity of the two ore samples, and only quartz material. The 75 % quartz and 25 % iron ratio yielded coarser fractions than quartz only in the range of 150300 µm. It is evidently observed that the addition of quartz mineral with increasing percentage tend to reduce ...

SAG vs. AG Mills: Understanding the Key Differences ball mills supplier

SAG mills use a combination of steel balls and rock particles as grinding media, while AG mills use only the ore itself. Both types of mills are used for grinding ore in mineral processing operations, but SAG mills are larger in size and can grind larger quantities of ore. AG mills, on the other hand, are smaller and are typically used for ...

CMM ore was ground in a rod mill, as is common before flotation testing, and PGM ore was ground in a ball mill, as is common before leach testing. The plant cyclone overflows could not be used for such purposes because of gravity gold recovery in the grinding circuit at PGM, and because of CMM flotation feed (cyclone overflow) sample aging.
