    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.
