frothers in processing of chromite mining

  • Chromium processing Britannica

    Chromite deposits are mined by both underground and surface techniques. Much of the ore is rich enough to be used directly for production of ferrochromium a rich lumpy ore containing more than 46 percent Cr 2 O 3 and having a chromiumiron ratio greater than 2:1 is preferred but ores with a lower ratio and as little as 40 percent Cr 2 O 3 are also used.

  • Frothers Froth Flotation ArrMaz

    The importance of frothers in mineral flotation is widely acknowledged in the mining industry. Frothers perform the following key functions in the froth flotation process Reduce surface tension of the liquidgas interface to enable froth formation. Hinder coalescence in order to stabilize bubble size.

    Flotation Frothers Frothing Agents. The next reagent that is added is the Flotation FROTHER. The frother strengthens the surface tension of the air that is injected into the flotation cell. As the air rises in the shape of bubbles they come into contact with the mineral laden collector which attaches itself to

  • Effects of frother type and froth height on the flotation

    About 70% of the UG2 reef consists of the gangue mineral chromite (FeO · Cr 2O 3 ). In the processing of UG2 ore by flotation for the recovery of platinum group elements (PGEs) the presence of chromite in the concentrates can cause serious downstream processing problems and a grade of less than 3% Cr 2O 3 is sought.

  • Froth flotation

    Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing paper recycling and wastewater treatment industries. Historically this was first used in the mining industry where it was one of the great enabling technologies of the 20th century.

  • Frothers and Flotation Froth Mineral Processing and

    Good flotation frothers have branched hydrocarbon radicals and form loosely packed gaseous films at the liquid/gas interface. Their hydrophilelipophile properties must be properly balanced and for most good frothers the HLB values are close to 6. This allows them to cooperate actively with the adsorbed collector in the moment of particletobubble attachment.
