Potash Laboratory Flotation Tests

Insoluble-Slimes Flotation. Batch insoluble-slimes flotation tests were conducted in a Fagergren laboratory flotation cell. In each test, 1 kilogram of ore was scrubbed 5 minutes at 27-percent-solids pulp density in a saturated brine at a 4.22-m/sec (830-ft/min) peripheral impeller speed.

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.

An Overview Of Potash Flotation

Flotation of potash was developed in the early 1930s. Amines are widely used for flotation of sylvite (KCl) from halite (NaCl) and insoluble materials such as clays. Amine collector is also absorbed by clays. Therefore, clays are usually separated by scrubbing and de-sliming prior to flotation. Alternatively, slimes can be floated ahead of ...
