2. 2. 2. Flotation Experiments Reverse cationic flotation batch tests were conducted using 1kg of fluorspar tailings in 2.5l Denver D12 flotation cell at pulp density of 40% solids, impeller speed of 1000rpm and air flowrate of 60%. Before flotation, the pulp was first conditioned with starch for 4min and then conditioned with collector for 4min.

The nature of hematite depression with corn starch in the ...

These studies are of importance since mono ether amine, used as a quartz collector in the reverse flotation of iron ore, also has an affinity towards hematite. Captive bubble contact angle measurements were performed to determine the role of starch, and the significance of the order of addition in the reverse flotation of iron ore . Micro-flotation tests have been performed on pure hematite samples to determine the change in recovery when the order of addition of mono ether amine and corn ...

Extraction of Iron from Haematite-xinhai

Reverse flotation method. Haematite reverse flotation method is a method used for the extraction of iron from haematite, which uses ionic or cationic collectors to float gangue minerals from raw ore. The anionic collector reverse flotation method is mostly used when the pH value is 8-9. It is used to treat quartz-containing gangue minerals.
