Cobalt And Nickel

Early in 1914 a parcel of copper-nickel-cobalt ore, weighing several tons, was received in London for valuation from the 'Cármenes mine, Spain'. This somewhat vague statement of locality refers without doubt to the group of mines in the district of Cármenes, province of León, situated about 6 km. E.N.E. of Viilamanín, a statisn on the railway from Gijon to León and about 40 km. N. of the latter city. The ores of these mines are described as consisting of sulphide minerals of copper, cobalt, and nickel in a gangue of dolomite.

The Given

This paper looks at substantiating the choice of a pyrometallurgical technique for processing of copper-nickel sulphide concentrates with a high concentration of platinum group metals. For this, it is proposed to use a modified SWOT analysis, which was also tested. The paper considers a classical SWOT analysis and its stages and gives examples of its application in different industries. Constraints have been identified for the pyrometallurgical processes recommended for analysis. Internal and external factors have been defined for the recommended pyrometallurgical processes. Each of the factors has been assigned relevance and impact coefficients with regard to an appropriate process. The obtained results have been included in an integrated estimator matrix. The obtained results have been evaluated on the basis of such indicators as overall, internal and external SWOT coefficients expressed as figures. The resultant data served as the basis for recommending the relatively most effective processes that would enable to achieve the project goals. This study can be used to issue recommendations on choosing the most advanced pyrometallurgical techniques for copper-nickel sulphide concentrates that will help reduce the number of processes involved and conduct a further detailed feasibility study. The given indicators may change considerably depending on the factor linked to the production hazards. That’s why a stability calculation was performed additionally for the overall SWOT estimates in relation to this criterion. The change dynamics of the overall coefficients is reflected in the graphs. Depending on the selected level of production hazards some processes may swap on the efficiency scale. The authors offer their recommendations on optimum processes that will enable to achieve the project goals considering the above mentioned factor.

The scope of the discussion embraces the problems connected with development and improvement of geological information processing methods and systems, as well as modeling of primary mineral deposits in exploration of side rock mass and deep horizons of the deposits under mining and in new areas with intent to discover potential copper-nickel sulphide mineralization. The target of the research is the geological and geochemical preconditions and signs of sulphide mineralization in the potentially ore-bearing Tangaralakh field adjacent to the deposits of the Talnakh ore-magmatic system. The integrated research is based on the conventional different-rank geological, geochemical, magmatic, structural, tectonic, lithological and stratigraphical preconditions and signs of sulphide copper-nickel platinum-bearing ore in the Norilsk Region. The geochemical search of ore objects in the Norilsk Region provided the best results in case of the geological and structural analysis of spatial interactions between geochemical abnormalities as the geochemical zonality is yet the chief factor in the mineralization prediction. This method of improvement of geological-geochemical information processing and modeling of mineral deposits was tested in geological-geochemical modeling of the Talnakh ore province bodies. From the research findings, the structural and tectonic conditions of localization of the potentially ore-bearing Tangaralakh intrusion were determined. The structural modeling of geochemical field of the mineralization revealed the types of geochemical associations marking different compositions of sulphide mineralization in disseminated ore in different sections of the Tangaralakh intrusion. It is found that the geochemical zonality coincides with the mineral zonality of the disseminated ore horizon formed at different stages of orogenesis. The similarity elements are found in the geological-geochemical models of the Tangaralakh potentially ore-bearing ore field and Talnakh ore field (ore-magmatic system).
