01/02/2005· Reagents used in the flotation of phosphate ores was recently reviewed by Sis and Chander , with emphasis on sedimentary ores. This paper focuses on the flotation of igneous phosphate ores. The largest deposit of igneous phosphate mined today is Kola, in Russia, producing 9 million tonnes of apatite concentrate per year . El Shall et
01/02/2005· Corn starch has been used in iron ore flotation in Brazil since 1978. The trade name of the reagent was Collamil, consisting of a very fine and very pure product. The amylose plus amylopectin content reached 98% to 99%, dry basis, the balance being represented by minor contents of fibres, mineral matter, oil and proteins.
01/05/2018· When comparing sodium hydroxide to sodium carbonate in the batch flotation of five different ores from the USA, Dean and Schack stated that sodium carbonate was more effective than sodium hydroxide as an overall pulp regulating reagent .
Mercaptobenzothiazole and aminothiophenole have been developed and perform well in oxidized zinc lead ore flotation (Marabini et
11/04/2019· In the flotation process of copper ore, xanthate mainly reacts with Cu2+. Therefore, when processing minerals containing more Cu2+ on the surface, the effect of xanthate is stronger, and the order of its action is: Cu2S > CuS > Cu5FeS4 > CuFeS2.

01/05/2013· As acidized sodium silicate is an inorganic reagent and works in neutral or weak acidic media, it might be a good alternative depressant for sodium lignosulfonate in fluorite flotation. The objective of this work was to develop a better chemical scheme to improve the separation of gangue minerals in fluorite flotation and the clarity of the recycled
01/07/2003· Phosphoric acid and derivatives is the most widely used depressant in reverse flotation of phosphate ore in order to depress the valuable mineral apatite while sodium silicate and gum arabic are used as depressants for the gangue minerals in direct flotation of the phosphate ores.
Used as the flotation collector for non ferrous metal complex sulphide ore with medium selectivity and strong flotation ability, which is suitable for polymetalic sulphide ore consisting copper, lead zinc and so on. In the natural loop, it is particularly effective in
