Jan 01 2017 In the first set no depressants were used and the ore was floated in the presence of the collector and the frother as the only reagents Second set of flotation experiments was performed using conventional depressants sodium cyanide and zinc sulphate Third set of flotation experiments was carried out using chitosan as the only depressant.Various flotation experiments including micro flotation and batch flotation of laboratory and industrial scales were conducted in order to compare the depression selectivity of SS versus SCS Outcomes of flotation tests at the different flotation scales demonstrated that hematite depression by SCS is around 3 3 higher than by SS.

First let’s change the amount of the Flotation Depressants used The valuable mineral that isn’t liberated from the unwanted mineral will begin to be depressed along with the waste For the floatation operator the change that will become most apparent is that the color of the froth will begin to reflect of the wanted mineral’s color This is because the froth is becoming purer as.Depressants The NASMIN depressant range is used in the depression of gangue minerals and the control of silicates in the flotation process and are critical to good metallurgical performance NASMIN depressants are extensively used in the depression of Pyrite and Pyrrhotite as well as for the control of silica and talc minerals.

DEPRESSANTS Froth flotation is the most efficient method for phosphate separation which is a physic chemical separation process based on the difference of surface properties between the valuable minerals and unwanted gangue minerals However the presence of clay slimes in the slurry after grinding consumes a large amount of reagents.Modern classification of flotation reagents is based on the function of a particular reagent On this basis reagents are divided into collectors frothers regulators and depressants Collectors are a fairly large group of organic chemical compounds which differ in chemical composition and function.
