3. Partial mixed flotation process. The process of first floating two useful minerals in the ore together to obtain a mixed concentrate, and then separating the mixed concentrate from the single concentrate, is called partial mixed flotation process (Figure 7). This is the most widely used type of process in production.

In a typical grinding mill application, the grinding media eventually fractures and wears into a fine metallic powder because of the heavy re-circulating load in the mill. Energy is unnecessarily wasted to mill the milling media. As shown in Figure 3, the trunnion magnet is mounted at the ball mill discharge point to replace a trommel screen.

The Knelson centrifugal concentrator is often arranged at the outlet of the ball mill, we analysis the ball mill discharge firstly, to know the metal distribution of different particle sizes. As can be seen in the above table, the major particle size is 0.045mm-0.6mm, with 75.26% of productivity, and the distribution rate of gold is up to 83.76%.

The ball mills are operated at a ball charge volume of 30–32% and 78.5% critical speed. The SAG mill trommel undersize is combined with the ball mills' discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed ...
