The depression effect and mechanism of NSFC on dolomite
17/03/2016· The aim of the present study is to investigate the effect of NSFC on dolomite depression during phosphate ore flotation. The depression performance of the NSFC was evaluated by flotation experiments of pure mineral, artificially mixed sample and real phosphate ore. In addition, the adsorption mechanism of NSFC on dolomite and collophane surface
Understanding the depression mechanism of sodium
Due to these minerals similar soluble properties and structures, direct flotation is inefficient. Therefore, reverse flotation of carbonate gangue and depression of apatite has been practiced by predecessors [4,6]. Thus, the understanding of depression mechanism of apatite and other calcicolous minerals flotation has attracted much attention.

Froth Flotation of Iron Ores sapub
With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. In over half a century’s practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron ore.

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 more of the wanted mineral’s color.
