  • A Comparative Study of Kinetics of Flotation of a Copper

    beneficiation of nickel ores. Flotation of a Canadian nickel ore by N-hydrocinnamoyl-N-phenyl hydroxylamine (HCNPHA), also called N-phenyl hydrochuiamohydroxamic acid (see Figure 1 for structure) and the comparison of performance of the synthetic collector with that of potassium amyl xanthate (PAX) are reported here. Such a comparison of a synthetic collector with that used in the

  • Cadillac Announces Results of Scoping Level Flotation Test

    2013-10-21· Nickel sulphides, occurring mainly as pentlandite, were 53% liberated in the pit area, and 46% liberated outside the pit. It was also noted that there is a high nickel content resident in pyrrhotite and pyrite; the deliberate recovery of these by flotation will improve overall nickel recovery. Test work grades better than Resource grades

  • Teck's CESL Nickel Process: Advancing Towards a Commercial

    Smelting and refining of massive sulphides begins with the flotation of ore, typically in the range of 0.2-2% nickel, to an acceptable concentrate grade of 10 to 20% nickel. Concentrate smelting produces a high grade nickel matte which is then refined hydrometallurgically.

  • How to Test for Iron and Nickel – Canadian Conservation

    The nickel test paper can detect 10 mg/L (10 parts per million) or more nickel ions in solution. In an ideal spot test, only one metal element produces the colour change. In general, however, other metal elements may also cause a similar colour change.

    flotation circuit test Although the test work programme targeted split flotation of nickel and copper, the ore samples re just as a amenable to bulk flotation techniques with similar recoveries. The individual metal for any bulk grades flotation are yet to be assessed. The availability of bulk flotation is likely to provide alternative strategies for the processing and marketing of ore

  • The Effect of Oxidation on the Flotation Behaviour of

    TEST SAMPLES AND PROCEDURE A nickel-copperore sample from rod mill feed was used in the first part of the testwork. In this case, 1.8 kg representative ore samples (-10mesh) were ground using closed stain1ess or mild steel mill and rods under air or oxygen-deficient conditions (provided by using nitrogen) to obtain about 55 per cent -200 mesh. The samples used assayed 1.22 -1.58 per cent Ni, 0

  • Preconcentration strategies in the processing of nickel

    2015-08-01· Results of previous studies of flotation testing of nickel laterites at laboratory scale are reported. A brief literature review is followed by a description of some laboratory flotation test work conducted on a sample of Ni laterite from Western Australia. This sample has been designated "siliceous goethitic" (SG) as suggested by its generic mineralogy. Detailed mineralogical

  • Effect of calcium and thiosulfate ions on flotation

    2002-01-01· For example, thiosulfate reduced the activating effect of calcium in nickel flotation but increased it in copper flotation, in region where galvanic interaction with mill iron was effective. In addition, calcium seems to have prevented the "activating" effect of thiosulfate on pyrrhotite in the end of the test. These observations are consistent with the conclusion made by

  • NICKEL AND COBALT ORES: FLOTATION

    Flotation Practice in Nickel Sulde Deposits Nickel sulRde minerals such as pentlandite can, in general, be separated from their gangue by Sotation using a thiol group of collectors like xanthates and alkyl dithiophosphates in the presence of variety of activators, depressants and dispersants.

  • FPX Nickel Metallurgical Optimization Achieves Significant

    2019-08-06· The recent improvements in nickel recovery are related to on-going optimization test work of the flotation process and can be mainly attributed to eliminating a stage of sample handling in the laboratory test work. Previous metallurgical test work conducted flotation tests on stored magnetic concentrates, which had been produced during previous days magnetic test work. Direct testing of

    In this paper, the flotation behaviour of nickel-copper ores processed in the Sudbury area isdiscusse~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.
