Two biodegradable quaternary ammonium salts were synthesized and used as cationic collectors in processing iron ores by froth flotation.The flotation behaviors of iron minerals with the new biodegradable quaternary ammonium collectors were investigated by micro-flotation tests of quartz sio2 and magnetite fe3o4.It was observed that the new biodegradable collectors were effective.
Galena flotation of complex lead-zinc-iron sulfide ores.Under appropriate pulp potential in pcf process, the flotation speed is fast and the flotation flowsheet is simpler than commonly used ones.The key factor of pcf is the redox reactions in the system, and according to the mixed potential theory, in the grinding-flotation system,.
Constituent of a flotation pulp, originating from non-sulphide gangue, grinding in steel mills, and oxidation of sulphides.Iron oxidesulphide fines are the primary component of acid mine drainage that control scavenging of toxic cations.Such fine particles are produced during grinding of iron ores pose a serious problem for flotation.

Froth flotation of iron ores.Adsorption of starch products and laurylamine acetate.
Bioleaching is the extraction of metals from their ores through the use of living organisms.This is much cleaner than the traditional heap leaching using cyanide.Bioleaching is one of several applications within biohydrometallurgy and several methods are used to recover copper, zinc, lead, arsenic, antimony, nickel, molybdenum, gold, silver, and cobalt.
Flotation of iron ore the main objective of iron ore flotation is to upgrade the concentrate by removing silicates andor phosphorus-containing minerals.The use of silica flotation has increased in recent decades.The trend will continue as more complex ores have to be mined and higher-grade iron ore concentrates with fewer.
The first flotation separation for the rejection of magnesite was reported by doerner and dwigh 1930s.Flotation of mg carbonates is typically carried out by using fatty acids, since these collectors give insoluble complexes with all divalent cations.Determination of the appropriate depressing reagents for sinking valuable minerals in the presence of collectors for carbonates is a.
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 indicated many advantages over other traditional techniques pyro- and hydro-metallurgy.

Froth flotation of iron ores.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.
E bio-collector.Microbial flotation reagents are currently gaining attention as natural bacteria can be used in place of toxic chemicals from the environmental point of view, e.G.Bacillus polymyxa, paenibacillus polymyxa and rhodococcus opacus, for flotation of iron oxide minerals.F ionic liquids.
The results showed that with starch sodium humate mass ratio of 2 1 as combining depressant for iron ores,oxp c- 1 mass ratio of 5 1 as combining collector for gangues,iron concentrate with fe grade of 65.17 and fe recovery of 88.14 was gained.
Based on analysis of the findings, the clarification, bio-treatment inside the tailing ponds or the use of constructed wetlands as polishing stage prior to water reuse are suggested as feasible treatment approaches in view improving the management practice of flotation wastewaters during the dressing of copper ores in the katanga province.
