Flotation Reagents for NonSulfide Ores Evonik has a wide range of experience supplying performance chemicals to the mining industry. Our global reach throughout the major mining regions provides customers with local support to help them enhance performance and optimize value.

Mineral separation by froth flotation is widely used around the world for the beneficiation of sulfide ores. Flotation products (typically concentrate) are subjected to metallurgical processes for metal extractions. Bioleaching as a metallurgical procedure indied many advantages over other traditional techniques (pyro and hydrometallurgy).

Benchscale flotation tests were performed in an XFD type flotation cell (selfaeration) of which the volume for rougher flotation and cleaner flotation were L and 1 L, respectively . 500 g actual magnetite ores (− mm, 90%) were used in the rougher flotation with a speed of 1650 r/min.

Apr 01, 1992 · The author provides an authoritative review of sulphide mineral collector properties and use with specific ores. Special emphasis is placed on the different flotation mechanisms involved in particle capture of both sulphide and nonsulphide minerals on reagent selection.

Jul 01, 2018 · The work of the researchers on iron ore flotation is basically focused on achieving selectivity through different collectors and depressants, with other reagents contributing towards an enabling pulp environment. Five main classes of collectors are used in iron ore flotation:

Nov 20, 2020 · This method is suitable for the flotation of iron ore with high grade and gangue which is relatively easy to float. Cationic collector: when the pH of the pulp is adjusted to 8~9 with sodium carbonate, starch, dextrin, tannin and other iron ore substances are used to inhibit iron minerals. Then, use amine collectors to remove quartz gangue.

May 16, 2016 · Flotation of Copper Ores. In most plants engaged in the flotation of ores containing copperbearing sulphide minerals with or without pyrite, pine oil is employed as a frother with one of the xanthates or aerofloat reagents or a combination of two or more of them as the promoter. Lime is nearly always used for maintaining the alkalinity of the ...
