Review of flotation of feldspar
In the first flotation stage, mica is removed with an amine collector. In the second stage, titanium and iron oxide minerals, such as ilmenite and magnetite, are removed using an anionic collector. In the third stage, feldspar is activated with fluoride ions and floated with an amine. The residual product is usually high grade quartz.

Gold Extraction & Recovery Processes
Flotation. Flotation is one of the most important gold recovery processes and its main restriction is to recover coarse gold particles ranging from 400 to 250 µm. This process recovers fine particles of free gold, gold associated in any form with sulphides, and native gold present in polymetallic deposits with certain degree of oxidation.

Abstract. Within the flotation process the pulp phase chemistry has a strong effect on the froth phase and therefore the manipulation of pulp chemistry factors such as the pulp potential (Eh), pH, dissolved oxygen (DO) and ionic strength (IS) can improve flotation performance. Stability column and batch flotation tests were performed in the ...

Physiochemical separation of iron ore
Aluminum-containing minerals in iron ore are detrimental to blast furnace and sinter plant operations. The two major aluminum-containing minerals in iron ore are kaolinite (Al 2 (Si 2 O 5)(OH) 4) and gibbsite (Al(OH) 3). Some progress has been made in using flotation to separate kaolinite from hematite.
