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

Flotation of Nickel-Copper Sulphide Ore: Optimisation of

the flotation recovery of Ni, Cu and Co from a nickel-copper sulphide ore. The effect on flotation performance of various parameters such as pH, collector dosage, % solids and depressant dosage at different levels was investigated. Therefore, the main objective of the study was to optimize the process parameters for the flotation of base metals from a nickel-copper sulphide ore. 2. Materials and

Challenges in processing nickel laterite ores by flotation

Challenges in processing nickel laterite ores by flotation

Jun 10, 2016 Jun 10, 2016 It should be added that segregation of laterite ores prior the flotation process has shown some improvement in upgrading nickel. The segregation process relies on the addition of calcium chloride or sodium chloride and carbon allowing the formation of nickel and iron chlorides at temperatures between 900 and 1150 C.Iwasaki et al., (1961) and Nagano et al., (1970) have reported nickel

Cobalt appears in the nickel concentration and the cobalt is subsequetly recovered. Flotation has developed from the treatment of simple ores to the ever more complex ones that are being fund today. Thus, for example, the three metals in copper/lead/zinc ore

Ammonia Leaching as a Pre-Treatment for the

conventional mineral processing technologies for the treatment of low grade oxidised PGM ores. The exposure of the ore to the atmosphere leads to the formation of an oxidation layer (consisting of base metal oxides) which inhibits the flotation process that requires a clean mineral surface to be effective

Nickel Ore Dispersion Evaluation and Consequences in

Nickel Ore Dispersion Evaluation and Consequences in

Jan 06, 2016 Jan 06, 2016 Nickel ore dispersion before flotation using different reagents was investigated on a bench scale to improve metallurgical recovery and selectivity. The nickel ore had a content of 0.8 pct nickel and 14.5 pct MgO. A positive linear correlation between MgO and Ni was found. Carboxy methyl cellulose, both pure and combined with Na2CO3, was the best dispersant used

Ore deposits formed by oxidation and supergene enrichment

Ore deposits formed by oxidation and supergene enrichment

Ore Deposits Formed by Oxidation and Supergene Enrichment When ore deposits are exposed to the oxidation zone they are weathered and altered with the country rocks. The surface waters oxidize many ore minerals and yield solvents that dissolve other minerals. An orebody thus becomes oxidized and generally leached of many of its valuable materials down to the groundwater table, or to
