The magnetite to coal ratio maintained in all the experiments was 4:1 by weight. The slurry was pumped into the cyclone keeping the by- pass valve fully open and then this valve was adjusted to obtain the required pressure (1.5 kg/cm2) at the inlet of the cyclone. This pressure was kept constant in all the experiments.Web

magnetite is used almost entirely by the New South Wales coal mining industry during coal beneficiation. When finely milled, magnetite remains suspended in water, producing a dense medium suitable for separating impurities from coal. The magnetite is easily recovered by applying a magnetic field.

Compared with the SLon magnetic separator, the operating cost of reverse flotation is much higher. The flow sheet in Figure 9.16 provides an example of how to minimize the feed to flotation to reduce the total production cost. The iron ore is composed dominantly of specularite with only about 0.5% magnetite, and the gangue mineral is mainly quartz.Web
