Monomineral flotation results showed that the use of a new reagent S-cyanoethyl N, N-diethyldithiocarbamate enhances the flotation activity of chalcopyrite, in contrast to flotation with butyl xanthate, and reduced the flotation ability of arsenopyrite, which makes this reagent promising for its use in the selective flotation of complex sulfide ores.

Ore Dressing

The tradition way of open pit mine design just takes the operating and capital costs into account while the ecological costs of mining to ecological environment is not a concern at all. For this concept, based on the mine ecological footprint and eco-cost models which have been built by author, the ecological cost allocation models which take mining, stripping and ore dressing as incentive are built. It contains allocation models of unit mining ecological costs, stripping ecological costs and ore processing ecological costs. Moving cone elimination algorithm and iteration method is used for a open pit metal mine to optimize ultimate pit. The studies show that the pit optimization which contains ecological costs has a great impact on the ultimate pit. Compared to the pit optimization with an end treatment, ecological costs are contained in the pit design is better for either economy or environment.

Before And After

In this study, chitosan polymer was tested as a potential selective green depressant of pyrite in the bulk flotation of galena (PbS) and chalcopyrite (CuFeS2) from sphalerite (ZnS) and pyrite (FeS2) using sodium isopropyl xanthate as a collector and 4-methyl-2-pentanol (MIBC) as a frother. Flotation tests were carried out in a D12-Denver flotation laboratory cell in the presence and absence of chitosan and/or sodium cyanide depressant which is commercially used as pyrite depressant in sulfide mineral flotation process. Flotation recoveries and concentrate grades (assay) were studied as a function of polymer concentration and flotation time. It was found that at 50 g/ton, chitosan depressed 5.6% more pyrite as compared to conventional depressant NaCN at its optimum dosage. Furthermore, the measured assay values of pyrite in concentrates dropped by ~1.2% when NaCN depressant was replaced with chitosan polymer. Zeta potential measurements of galena, chalcopyrite, sphalerite, and pyrite suspensions before and after chitosan’s addition revealed that the polymer has preferential adsorption on pyrite minerals as compared to other sulfide minerals specially galena. Results obtained from this work show that chitosan polymer has a promising future as a biodegradable alternative to sodium cyanide for the purpose of depressing pyrite in sulfide minerals flotation.
