Flotation Of Mixed Oxide Sulphide Coppercobalt Minerals

Jul 01, 2019 With mixed oxide-sulphide ores, it is accepted practice to concentrate sulphide and oxide minerals in separate flotation processes. While flotation is a common method to concentrate sulphide ore in the DRC, oxide ore requires sulphidisation prior to flotation with xanthate collectors Crundwell et al., 2011 .

Sulphidation Of Copper Oxide Ores For Flotation

Copper oxide ores have occasionally been treated via froth flotation via sulfidation of the oxide minerals with certain chemicals which react with the oxide mineral particles to produce a thin rime of sulfide usually chalcocite which can then be activated by the froth flotation plant.

Effect Of Reagent Chemistry On Flotation Of Mixed Copper Ore

Effect of reagent chemistry on flotation of mixed copper ore ... The Malanjkhand porphyry copper deposit is of mixed type both copper sulphide and copper oxide minerals and lean grade ore. After continuous mining, the deposits are now left with low grade ores which contain copper sulphide as the major valuable mineral along with higher ...

The Effect Of Surface Oxidation Of Copper Sulfide Minerals

The industry is well aware of the difficulty in treating copper ores in the presence of clay minerals. In this study, the effect of bentonite on the flotation of chalcopyrite a primary copper sulfide mineral and chalcocite a secondary copper sulfide mineral was investigated in terms of surface coating.

Development And Optimization Of Mixed Sulphideoxide

of xanthate flotation of the sulphide minerals, followed by acid leaching of the oxides. The traditional method applied for the flotation of copper oxide or mixed ores is sulphidization, which was first developed with industrial success on Pb-Zn oxide ores in Australia Crozier, 1991. The method involves multistage addition of sodium

Interaction Effects Of Flotation Reagents For Sag Mill

Abstract Flotation reagents have a complex behaviour in the beneficiation of base minerals in clayey ores. Interaction effects of reagents on the efficiency of copper flotation for a highly clayey low-grade sulphide ore were investigated using a central composite design. Preliminary results showed that sodium-isopropyl-xanthate SIPX and

Principles And Practice Of Sulphide Mineral Flotation

Synopsis. This paper presents both the fundamentals of sulphide mineral flotation and the practical aspects of sulphide ore flotation. The fundamental aspects of the flotation of sulphide minerals both in the absence and presence of thiol collectors are discussed in relation to their crystal structure, surface chemistry and electrochemical characteristics.

Effect Of Desliming On Flotation Response Of Kansanshi

The flotation response of sulfide minerals in the Kansanshi mixed oxide-sulfide copper ore is superior compared to oxide minerals, for the given flotation conditions. The grade-recovery profiles and the flotation kinetics show improved results for copper sulfide minerals than oxide minerals.

Effect Of Pulp Potential On The Flotation Of A Sulfide

Aug 01, 2005 Surface oxidation of secondary minerals, such as chalcocite, bornite and digenite, present in the Salobo copper ore makes their flotation difficult and requires excessive reagent consumptions. Two possibilities for reducing the collector and fr other additions were investigated. These were sulfidization of the pulp prior toflotation and using nitrogen to replace air in flotation.

The Effect Of Oxidation On The Flotation Behaviour Of

In this paper, the flotation behaviour of nickel-copper ores processed in the Sudbury area is discusse with emphasis on the effect of oxidation on individual minerals, pnmarily pyrrhOlite. In general, moderate oxidation of a freshly ground ore promotes the flotability of all principal sulphides in the ore leading to a bulk flotation concentrate.

Effect Of Desliming On Flotation Response Of Kansanshi

Kansanshi Sulfide Oxide Copper Ore, Flotation, Baseline, Desliming 1. Introduction Flotation recovery of valuable minerals from ores is a function of particle size and it is therefore anticipated that variation in the granulometric characteristics of feed to a flotation process will affect flotation performance. Size of mineral

surface structure of copper oxide, making its properties similar to that of copper sulphide surface 16. So far, sulphidizing flotation has become the most widely-used industrial approach for the utilization of copper oxide ores. If xanthate collector is used solely in complex copper oxide ores, its collection capability is limited.

Oxidative Hydrometallurgy Of Sulphide Minerals

Sulphide minerals are one of the most important sources of value metals, such as gold, silver, copper, zinc, etc. Due to the strong sulphur binding to these minerals, metals are usually extracted by pyrometallurgical route or hydrometallurgy with chemical oxidation. Of these, hydrometallurgy apparently has a lower environmental impact, which has
