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 ...

The dosage of a collector is an important factor that determines the efficiency of a froth flotation process. The representative sample of the carbonatitic Palabora copper ore ground 45 % passing 75 µm was frothfloated with sodium isobutyl xanthate (SIBX) collector at 60, 70, 80, 90 and 100 g/t dosages. The concentrates and tails were dried and analysed. The results obtained showed that the ...

Figure 14 shows the size distribution of the copper ore sample after ball milling under different milling time. Compared to the oxide copper ore without milling (Fig. 2), the ball milling process has a significant effect on the size distribution of ore particles. As expected, the amount of the relatively coarse particles ( μm) in ore ...

The water can wash away the fine particles in time to avoid overgrinding. The wet ball mill has a low noise, and low environmental pollution. The wet ball mill has a simple transportation device with less auxiliary equipment, so the investment is about 5%10% lower than that of a dry ball mill. The grinding particle size is fine and uniform.
