A New Reagent For Selective Flotation Of Copper Sulphides. After two minutes flotation a copper grade of 5.2 per cent with 52 per cent recovery could be attained, against a grade of 2.5 per cent and a recovery of 44 per cent in the case of kax.the efficiency of this new collector has been ascertained on two samples of complex sulphide ores of.
Flotation Reagent. Flotation reagents have two important structural features: a functional group consisting of donor atoms or ligands, and a substituent group, which is hydrophobic consisting of alkyl aryl hydrocarbon chains in the case of collectors and frothers, or hydrophilic in the case of modifiers (except for inorganic modifiers, which comprise mainly inorganic bases and metal ions).
Oct 01, 2019· The standard technique for processing the copper sulphide ores is by flotation, which is both economical and suitable as per the environmental standards. The most important factor in flotation of sulphides is the choice of reagents. In the past, industrial flotation experiments with the various copper minerals were generally conducted with
May 21, 2020· The copper extraction and back-extraction can be completed in the ammonia solution. N902 It has the advantages of high extraction saturation capacity, good phase separation effect and high acid resistance. In the flotation process of copper ore, the beneficiation reagent is an important factor that determines the flotation effect.
Flotation reagents consist of copper sulfate as activator, PAX and AF208 as collector and the frother is Dowfroth 250. Flotation is conducted at natural pH (O'Rourke et al., 2000). At the Snip Mine in British Columbia, Canada, the gold ore is floated at natural pH value (8.5) using Aerophine 3418A and a dithiophosphate; the frother is Dowfroth 250.
Jul 04, 2017· The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%TCu (open pit mines) and 1-2%TCu (underground mines) is of
The sequential copper–lead–zinc flotation practice utilizes several major reagent combinations in sequential copper–lead flotation, which include: bisulfide method, starch/lime method and soda ash/SO 2 or lime/SO 2 method. The bulk copper–lead flotation with depression of zinc followed by copper–lead separation and re-flotation of
