Froth Flotation of Tungsten Ore. Flotation of Wolframite Including ferferite and huebnerite Wolframite based tungsten exhibits very similar flotation properties to that of cassiterite hence it is floated in an acid medium using sulphosuccinimates Cyanamid S3903 or Allied Colloids CA 540 or styrene phosphonic acid SPA, and is floated as cassiterite.

Swapnil-Froth Flotation |authorSTREAM

This pH factor is modified with the help of the substances called pH MODIFIERS. Alkalinity in a solution is maintained by the addition of Lime, Sodium carbonate , and to a lesser extent NaOH and Ammonia . Sulphurous and Sulphuric acids are used to lower the pH. Lime is widely used in the form of Milk of Lime, to maintain the pulp alkalinity.

Selectivity of Benzyl Hydroxamic Acid in the Flotation

During the flotation process, collectors can anchor on the mineral surface as a medium between mineral and air bubbles Rao and Forssberg, 1991. In the present flotation of ilmenite ore, fatty acids and their modified products commonly serve as collectors industrially.

Study on the Effect of Fe3 on Zircon Flotation

The effect of ferric ions Fe3 on the flotation of zircon and cassiterite using sodium oleate NaOL was investigated by single mineral flotation tests, adsorption density tests, zeta potential measurements, solution chemistry analyses, and FTIR analyses. It is difficult for zircon to be separated from cassiterite by using NaOL alone.

PowerPoint Presentation

2017-5-12It is necessary for the PH of the flotation pulp to be at he correct value and held relatively constant, for maximum selectivity and recovery. Cassiterite flotation is nearly always performed in an acid environment, the exact value depending on the ore source and collector to be used . Sulphuric acid is used for PH adjustment in most cases.
