    Shipment of Metal Sulphide Concentrates UN 3077 - Skuld

    The term "Metal Sulphide Concentrates" ("MSC") is a general description casting an umbrella over a number of concentrates such as iron, lead, lithium, zinc, copper, aluminium, nickel, magnesium, etc. Please see the link that provides maps over different mine locations.

  • leaching of metal sulphide concentrates at atmospheric

    Leaching of Metal Sulphide Concentrates at Atmospheric

    A new process for leaching zinc sulphide concentrates with gaseous mixtures of SO2 and O2 in aqueous solution is described. The reaction of SO2/O2 with Rosebery, Mt. Isa, Broken Hill and Elura zinc concentrates yields zinc and iron sulphates, elemental sulphur and some sulphuric acid.

  • the hydrometallurgical treatment of base metal sulphide

    The Hydrometallurgical Treatment of Base Metal Sulphide

    A new process is described which allows for direct recovery of base and precious metals (Au and PGM’s) from sulphide concentrates or other feedstocks. The process was developed initially for application to ores or concentrates that are too low-grade for economic treatment by the conventional smelting and matte leaching process (for PGM’s).

    US6699302B1 - Treatment of metal sulphide concentrates

    A process for treating a metal sulphide concentrate which includes the steps of: a) roasting the concentrate to reduce the sulphide content of the concentrate, to a negligible value and b) melting the concentrate, under reducing conditions, in an electrically stabilized open-arc furnace, in particular a DC arc furnace.

  • metal sulfides

    Metal Sulfides

    Nonferrous metal sulfide concentrates containing arsenic, antimony, and bismuth can be treated prior to smelting by either pyro- or hydrometallurgical routes to recover these elements as by-products. During the thermal treatment, however, a minor part of these elements will remain as an undesirable impurity in the raw nonferrous metal produced.

  • biomineralization of metal-containing ores and concentrates.

    Biomineralization of metal-containing ores and concentrates.

    Biomining is the use of microorganisms to extract metals from sulfide and/or iron-containing ores and mineral concentrates. The iron and sulfide is microbially oxidized to produce ferric iron and sulfuric acid, and these chemicals convert the insoluble sulfides of metals such as copper, nickel and zinc to soluble metal sulfates that can be

  • copper extraction

    Copper extraction

    All primary sulfide ores of copper sulfides, and most concentrates of secondary copper sulfides (being chalcocite), are subjected to smelting.Some vat leach or pressure leach processes exist to solubilise chalcocite concentrates and produce copper cathode from the resulting leachate solution, but this is a minor part of the market.

    Intensification of Sulfuric Acid Leaching of Copper from

    A copper sulfide concentrate with a grain size of 0.074 mm (90%) and a copper content of 24.5% obtained by the flotation concentration of ore from the Udokan deposit and ozone with a concentration of 80–180 mg/L in a mixture with oxygen are used for the study. The concentrate is fed into a stirred reactor at a rate of 1–5 mL/s.
