بيت /Addition Of Flotation Reagents During Crushing And Grinding
Abstract Our recent studies revealed that the ground sulphide minerals in contact with water generate H 2 O 2 but its effect on the oxidation of pulp components and hence in deteriorating the concentrate grade and recovery in flotation has not been explored yet. In this study, the effect of depressant and collector additions during grinding on the formation of H 2 O 2 by metal sulphides and ...

The useful minerals of Jinchuan highgrade copper and nickel suphfide ores were mainly nickel and copper, whose grade were respectively % and %. The content of MgO and SiO2, main gangue components, reached %. The key to improve the separation indexes of flotation concentrate was to inhibit the gangue minerals effectively, therefore, the effects of different kinds of regulators on ...

Answer: The purpose is to break the valuable mineral grains free of the gangue minerals, so that they can be physically separated from each other. This makes it possible to produce a pure mineral concentrate using processes like froth flotation or magnetic separation. So if an ore consists of gra...

The flotation test results illustrate that the natural floatability of impurities increases with the grinding fineness, that is, the yield of floats increases without flotation reagents. For impact crushing and shear crushing, the floats yields are % and % respectively, accompanied by % and % impurity removal for ground materials with 5 min grinding. Subsequently, % ...
