The nickel silicates are treated using either pyrometallurgical or hydrometallurgical methods. The reagent practice in the flotation of nickel and coppernickel ores depends on three basic factors: mineralogy of the ore, flowsheet employed in
02/03/2014· FLOATATION REAGENTS Xanthate Application: It has a strongest collector ability for sulfide mineral, and also can be used as diferential flotation reagent for non ferrous ore. Its commonly used in lead and zinc ore galena mixed priority of the flotation.
27/12/2021· 10%· Albuquerque et al. addressed the pilot scale direct flotation for the concentration of a phosphate ore , using corn starch as depressant and natural coconut oil, ether polyalkylene glycol and sulfosuccinate as a collector, which resulted in a concentrate reaching 30.5% P 2 O 5 grade, at 80.8%
In the flotation of phosphate ores, fatty acids and their salts are commonly used as collectors to float phosphate minerals due to their low cost and strong collecting ability (Sis and Chander ...
The role of reagents utilised in iron ores flotation is reviewed. Desliming and flotation stages should be performed at pH levels as low as possible to reduce the expenses with caustic soda.
For the treatment of igneous ores in weathered material, apatite flotation is carried out using fatty acids as collector and corn starch and sodium silicate as depressants in ...
08/06/2016· The ore testing Laboratory of , in the selection of reagents for the flotation of various types of ores, uses that combination which gives the best results, irrespective of manufacturer of the reagents. The data presented on the following tables should be useful in selecting reagents for trials and tests, although new uses, new reagents, and new
Each ore type also responds differently to flotation under similar reagent schemes, which is not the case when treating porphyry copper ores. Therefore, each individual ore deposit and operating plant uses a different reagent scheme, which may indicate that for each ore, the reagent scheme has to be tailored through extensive laboratory and pilot plant work.
In the mining industry, cyanide is primarily used for leaching gold and silver from ores, but it is also used in low concentrations as a flotation reagent for the recovery of base metals such as copper, lead, and zinc. At many of these operations, cyanide treatment systems may be required to address potential toxicity issues in regard to the health of humans, wildlife, waterfowl, or
01/02/2005· The flotation performance of certain iron ore types is enhanced with the use of ether di amines in combination with ether mono amines. Amine is partially replaced by some kind of fuel oil in some concentrators. The emulsification of the fuel oil plays a
