Simultaneously it also can provide reference and guidance on the technology research of chalcopyrite flotation separation 2 Experimental 21 Chalcopyrite sample The chalcopyrite use for tests is produced from a mine in Yunnan province China The raw ore was manually crushed and then sorting to collect pure blocksFurther Details
The majority of chalcopyrite remains in the sulfur flotation tailings and can be readily recovered by flotation with different flotation reagents When amyl xanthate is used 85 of chalcopyrite can be recovered with a copper grade of 145 in a singlestage froth flotationFurther Details
1 The Separation of Chalcopyrite and Pyrite Method It depends on the ore property including the following two methods 11 Preferential Flotation This method is suitable for dense lump ores Under relatively coarse fineness chalcopyrite and pyrite can be fully dissociated and separated Separation Turn chalcopyrite first pyrite secondFurther Details
Chalcopyrite is typically processed pyrometallurgically subsequent to its separation from gangue minerals by ﬂotation which is a waterintensive process based on the different natural or induced surface properties of the valuable and gangue minerals 3–5Further Details
Mineral flotation is a waterintensive process in mining In order to sustain mining operations such flotation which rely heavily on water chapter 3 of the dissertation looks at using alternative water sources in this case reclaimed wastewater in the flotation of chalcopyrite ores this effort is to limit the mining industries dependence onFurther Details
Apr 01 2014 · Fig 9 shows chalcopyrite and pyrite recovery from cleaner flotation as a function of collector addition 89 chalcopyrite recovery was achieved in 8 min flotation without additional collector which is higher than that from the flotation of single chalcopyrite shown in Fig 3 It suggests that the presence of pyrite enhances chalcopyriteFurther Details
Flotation of copper sulphides is a traditional technique for processing the sulphide copper The presence of pyrite in copper concentrates especially the pyrite particles that are surrounded with the chalcopyrite is the most important problem of copper ore processing that leads to a decrease in the quality and grade of concentrateFurther Details
Chalcopyrite pyrite sphalerite and galena minerals ﬂotation tests were performed in a microﬂotation cell Xanthates were used as a collector and their carbon chain length was tested at dierent pH values As expected pH has a signi cant eect on ﬂotation and pulp potentialFurther Details
Sep 24 2013 · In the flotation process the surfaces of valuable minerals are converted from hydrophilic to hydrophobic by adsorbing xanthate When air bubbles are introduced the hydrophobic minerals will attach to the bubbles and float with themFurther Details
