Reverse Flotation - an overview ScienceDirect Topics

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.

Coarse and Fine Particle Flotation Recovery

Jun 02, 2016  In its early days flotation promised, not only the ability to treat slime, but also a great simplicity of flowsheets attributable to the fact that all that had to be done was to grind the ore to a fine pulp and then float it. Flotation was the powerful new tool to which all refractory ores would respond. Time, however, has shown that flotation ...
