oxidized copper ores has not been attended with the Barne success. Some earlier practice is briefly discussed. A semi-oxidizedore was treated at Kennecott(l) by a combination method including gravity concen-tration, ammonia leaching, and flotation. Sodium sulphide, calcium poly-sulphide, coal-tar creosote, and steam-distilledpine oil were the ...

ore was tested. Low selectivity and recovery problems occur in the flotation of this copper-rich ore since it includes secondary copper minerals causing high degrees of surface oxidation. Also, this ore contains high amount of clay and mica minerals. In order to increase the flotation performance of this ore, the effects of different types of ...
Flotation of Jinping refractory copper oxide ore activated by a combined reagent of amine and ammonium has been fully studied in present study. The results show that the combined reagent (i.e., ethylenediamine phosphate and ammonium bicarbonate) has a remarkable effect on flotation performance, which can not only effectively activate the refractory copper oxide mineral, but also …
May 24, 2019 The use of flotation conditioners process can increase the selectivity of the flotation process, enhance the effect of the collectors, and improve the conditions of the ore pulp. 1. Sulfurizing Reagent. Oxidized ore is generally formed by ionic bonding, and is highly hydrophilic. It is not easy to float oxidized ore with xanthate collector.
Copper ore deposits are reported from igneous, sedimentary as well as metamorphic rocks. The ores generally occurs as veins, disseminations and as bedded deposits. The principal copper bearing minerals are ... (KHXM) was synthesised in laboratory and was used as an auxiliary collector for enhancing flotation of oxidised copper minerals.
The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.

Authors’ comment: Generally, the copper porphyry ores are mined from several locations in the mining sites, thus, the mineral composition, oxidation degree, and copper grade vary greatly, which can affect the flotation performance. To overcome this problem, it is a common practice in a mining operation to blend these copper-molybdenum ores ...

The copper ore in Chilean copper porphyry deposits is often associated with molybdenum minerals. This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary. Therefore, in the mining operation, it is common to blend the ores mined from various spots and then ...
Flotation Process Lead Ore Processing Plant High Quality. Flotation Process Lead Ore Processing Plant High Quality. At the end of the flotation process, the lead has been separated from the rock, and other minerals too, such as zinc and copper, have been separated outiltering 4 after the ore is concentrated in the flotation cells, it flows to a filter, which removes up to 90 of the water.
flotation recoveries of oxidized copper minerals and oxidized lead ores. (Orwe, Grano, and Lauder, 1998; Kongolo et al., 2003; Castro, Goldfarb, and Laskowski, 1974). Studies by Lee et al. (2009) have indicated that hydroxamate co-collectors have the potential to improve PGM flotation recoveries from oxidized ores because they can selectively form
MSR for a preliminary sulfidization of the oxidized copper ore in the flotation chamber, i.e. by variant II. This procedure of sulfidization of the oxidized cop-per minerals with using of MSR was tested on a sample of the oxidized copper ore from the Balkhash region containing mass/%: Cu gener. – …

Jul 27, 2021 （2）Amine: Amine collector can also be a cationic collector, is a more commonly used collect in non-ferrous oxide ore flotation, has a strong collecting ability for copper oxide, mainly used with malachite and azurite ore and other copper oxide, especially deposits containing copper and zinc.
The research results showed that the pre-removal of carbonaceous mud - asynchronous flotation process got a better flotation results than the conventional process. Using the former approach the copper grade in concentrate achieved to 21.2% and the recovery achieved to 88.55% when the raw ore contained 2.63 % Cu, 0.04% Co and 6.63% C.
sulphidisation for flotation of oxidized sulphides has also been demonstrated (Newell et al., 2006). When introduced in the slurry, the sulphidiser dissociates into -the species H 2 S, HS-or S 2, depending on the pH. These ions react with the copper oxide minerals to form a sulphide layer on the surface of
Investigation into the mineralogy and flotation performance of oxidised PGM ore. ... recovery compared to equivalent tests conducted in the presence schemes generally used in the processing of oxidised copper ores (mixed sulfide/oxide) is also evaluated to determine their efficacy on oxidised PGM ores: alkyl hydroxamate (AM 28) co-collector ...
The flotation by surface sulphidisation of the oxidized copper-cobalt-bearing ore from Kimpe (1.97% Cu; 0.66% Co) was studied in order to evaluate its behavior by the analysis of its most influential parameters and their possible interactions.
