amine for chromite ores processing by froth flotation gold
Chromium values are recovered from pulverized chromite ore by agitating and aerating an aqueous pulp of said pulverized chromite ore containing an amine collector at a pulp acidity less than 25; and recovering a chromite containing froth as a concentrateCollector adsorption and thus chromite flotation at pH 2 is probably due to sulfate ion from the H2SO4 acting as a bridge between the positive amine and positiveFlotation of Chromite Ore

Keywords Flotation, Goldbearing ores INTRODUCTION Gold is a relatively rare metal and the average content in the earth's crust is about 3ppb The average gold grade of a low grade deposit is only some 3ppm and this low abundance makes the exploration, sampling, assaying and processing of gold bearing ores difficultEnvironmental Impact of Flotation Processing Valuable minerals in an ore can be separated from each other, and from worthless minerals, by the froth flotation process The need for a process to extract ore arose from major sulfide mineralizationEnvironmental Impact of Flotation Processing

The use of quaternary ammonium compounds as collectors in reverse froth flotation processes for example for calcite ores has long been known The meaning of the term “reverse froth flotation” is that the froth is used for carrying the gangue mineral rather than carrying the valuable concentrate, ie the gangue is recovered in the froth1 天前Handbook of Flotation Reagents Chemistry, Theory and Practice: Flotation of Sulfide Ores by Srdjan M Bulatovic • ISBN: • Publisher: Elsevier Science & Technology Books •Handbook of Flotation Reagents MESA
