Nickel Ore Processing. Nickel ore mainly consists of coppernickel sulfide ore and nickel oxide ore, beneficiation and processing of both methods is completely different. Coppernickel sulfide ore beneficiation methods, the most important is the flotation, magnetic and reelection is usually secondary dressing method.
Flotation of mixed copper oxide and sulphide minerals with . recover copper sulphides and oxides by otation from blended ore minerals. The copper sulphide recov ery did not decrease when processing the blended ore compared to treating the sulphide ore indepen dently.

Processing of the three ore types, namely leached ore, mixed float and sulphide, is through either an oxide circuit or a sulphide and transitional ore mixed float circuit. Treatment of the sulphide ore involves crushing, milling and flotation to produce copper in concentrate.
Flotation of mixed copper oxide and sulphide minerals with xanthate and hydroxamate collectors Copper oxide ores Copper sulphide ores Flotation collectors Mineral processing Alkyl hydroxamates such as sodium hydrogen sulphide (NaHS). When NaHS is used for CPS the pulp redox potential (Eh) is reduced to a target value between 192;450 and . Get ...

result of the mineral variations, the processing plant treats three distinct ore types, viz. oxide, sulphide, and mixed. The objective of this study was to investigate the floatability of a complex Kansanshi mixed copper ore comprising sulphide and oxide minerals, with a view to achieving an
Method for processing sulfide is oxidized copper ores extraction of copper and silver, including collective flotation of sulphide and oxide minerals of copper from crushed ore emitting collective concentrate, leaching of the bulk concentrate with stirring an aqueous solution of sulfuric acid involving ozone, hydrogen peroxide and ferric ions ...
Some of the most important copper oxide minerals are listed in Table In most cases, oxide copper ores contain more than one copper oxide mineral, and also contain mixtures of sulphide and oxide copper minerals. From a processing point of view, the oxide copper ores can be divided into the following five groups: Oxide copper ores.
Iron oxide copper gold ore deposits (IOCG) are important and highly valuable concentrations of copper, gold and uranium ores hosted within iron oxide dominant gangue assemblages which share a common genetic origin. These ore bodies range from around 10 million tonnes of contained ore, to 4,000 million tonnes or more, and have a grade of between % and 5% copper, with gold contents ranging ...

Jun 26, 2017· T he copper mining industry is reaching a turning point. Surface oxide deposits are depleting and copper miners are turning their attention to untapped sulfide ores found deeper underground. However, sulfides require more expensive processing techniques since they are not responsive to standard technologies that are used in oxide heap leaching.
flotation of mixed copper oxide and sulphide minerals. Particularly for mixed copper sulfide and oxide ores (, Minto Mine in Yukon, Canada) that are not amenable to LSXEW, the development of . Development and optimization of mixed sulphide/oxide copper ore .
Kansanshi copper mine is situated in the north western province of Zambia. Weathering has given rise to a vertically zoned profile comprising leached, refractory, oxide, mixed and hypogene sulphide mineralisation. As a result of the mineral variations, the processing plant treats three distinct ore types; oxide, sulphide and mixed.
ROASTING OF SULFIDE MINERALS In addition to common metals like copper, lead, zinc, and nickel a number of other ... the burning fuel. Hence, sulfide roasting is an autogenous process, that is, where no extra fuel is supplied. METHODS OF ROASTING ... In order to produce a mixed oxidesulfate product Sulfation roastis preferred.

We study the effect of one of the main parameters of flotation oredressing, specifically, alkalinity of the pulp, on the selective flotation of sulfide and oxide minerals of copper from the Udokan deposition ores (Chita oblast). It is found that the optimum values are pH = 9 for sulfide minerals of copper and pH = 10 for the oxide ones.
