The results prove that the structure of this sort of ore does not fit it for the desilication process by selective grinding but by direct flotation.

Application of sulphuric acid in dewatering process of bauxite positive flotation concentrate;

The article introduces the experiment of bauxite positive flotation concentrate filtration by small vertical disk filter,makes multiple regression analysis on the filtration operation time,feed concentration,vacuum degree and filter\'s capability experimental data by Minitab software,achieves favorable effect.

96 using sodium oleate as positive floatation collector.

Application of sodium silicate with different modulus in the Jinning phosphate rock flotation

The flotation experiments of washing concentration of Fijian gibbsite ore were conducted using ZYY as the collectors,sodium carbonate and sodium hexametaphosphate as the regulators.

Investigation of Raising Silicon to Aluminum Ratio of Gibbsite by Flotation;

As the run-of-mine ore has a high MgO content and the minerals therein are finely disseminated,direct-reverse flotation process was employed,while new types of collectors called MG and SR were introduced for direct and reverse flotation,respectively.

According to property of Yichang phosphorus ore,A positive-negative flotation process or a reverse flotation process was used for mid-low grade of phosphorus ore of Yichang mine.
