Flotation Rates of Non-Sulphide Minerals in Chalcopyrite

The behavior of non-sulphide gangue in chalcopyrite flotation circuits has been investigated. Plant and laboratory tests were carried out on five different ores and linear relationships were found to exist between the rates of recovery of water and free non-sulphide gangue in the concentrates although there was evidence from pilot plant tests that these were linear approximations to parabolic

Chalcopyrite Flotation without Collector Surface Chemistry

It has been reported that chalcopyrite can be floated selectively from an ore containing pyrite, sphalerite, and silicious gangue minerals without using a collector. Sodium sulfide was used as a promoter, presumably to clean the chalcopyrite surface of its hydrophilic oxidation products. Later it was found that the potential of the pulp, measured with a platinum-calomel electrode pair, was

The separation of chalcopyrite and chalcocite from pyrite

Apr 01, 2014· In order to simulate normal flotation circuits in plants, in this study, chalcopyrite and chalcocite recovery were maximized in rougher flotation by using stainless steel media in primary grinding and adding collector in the flotation stage. The rougher flotation concentrate was reground from 75 μm to 20 μm, and then subjected to cleaner

Flotation separation of chalcopyrite from talc using

Keywords: talc, chalcopyrite, flotation, separation, carboxymethyl chitosan Introduction Talc is a common gangue of copper-nickel sulfide ores around the world. Talc easily floats into a concentrate because of its surface hydrophobicity (Shortridge et al., 2000; Beattie et al., 2006). The Dongguashan copper mine is located in Tongling city, China.

Lime use and functionality in sulphide mineral flotation

Nov 01, 2019· In a flotation plant, Chalcopyrite flotation recovery was less affected, due to higher natural hydrophobicity, while pyrite was depressed to a similar extent by either lime or soda ash. The use of soda ash in place of lime in plant practice is however limited, mainly due to cost considerations, and confined to specific situations in which
