Reverse Flotation
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.

Artisanal and Small-Scale Gold Mining Without Mercury
In many countries, elemental mercury is used in artisanal and small-scale gold mining. Mercury is mixed with gold-containing materials, forming a mercury-gold amalgam which is then heated, vaporizing the mercury to obtain the gold. This process can be very dangerous and lead to significant mercury exposure and health risks.

Pyrrhotite floats best in acid circuits. The pH range for flotation for gold sulfide ores containing pyrite and arsenopyrite is generally between 7 and 9. Flotation may be carried out at higher pH values of 9–10, since this favors the depression of talc minerals and avoids the use of expensive gangue depressants.
