    4 Metallic silver may be obtained from sulfide ores

    Metallic silver may be obtained from sulfide ores by roasting to sulfates leaching with water and precipitating with copper. In the diagram below the material leaving the second separator was found to contain 90 silver and 10 copper.

    Sulfide Ore. any of several natural mineral formations consisting of metal sulfides. Metal selenides tellurides arsenides and antimonides are also classified among the sulfide ores. Sulfide ores are an important source for the production of Ni Co Cu Zn Pb Mo Bi Sb and Hg. They contain not only sulfides but also other minerals.

    Sulfide Ore Treatment Gold Silver Copper Cobalt

    Oct 20 2017 Several sulfide ore leaching methods were tested to determine the best base metal extraction technique as a first step in designing a process to recover the base and precious metal values. Leaching reagents used included dilute sulfuric acid sulfuric acid plus manganese dioxide ferric chloride plus hydrochloric acid and oxygen.

    Rebellious Ores Sulfides Selenides and Tellurides. The early day miners feared it and it happened a lot more often than they would have liked the easily worked rich surface ores they discovered on the surface gave way as they mined downward to a vein full of sulfides base metals and other nasty rebellious and refractory ores.

    Flotation of Silver Bearing Minerals from Sulfide Ores

    Mar 19 2018 Silver is an economically important component of many complex massive sulfide ores and often is produced as a byproduct during recovery of base metals from sulfide deposits. About two-thirds of the worlds silver resources are contained in base-metal sulfide deposits Reese 1991. These ores are beneficiated almost exclusively by flotation.

    Instead of relying on autoclaves or roasting to prepare a sulfide ore for traditional leaching our vibratory grinder on our circuit allows our leach to make contact with the precious metal encapsulated in the sulfide so leaching can occur. With the aggressive nature of our leach allowing us to process most ores in an hour our process allows.

    The product of melted sulfides is called a matte and is highly corrosive liquid. Converting that molten sulfide matte to metal is called smelting. Small scale smelting can be done in a crucible – in fact that is what a fire assay is. When smelting assays are done on high sulfide ores a couple of iron nails are added to the mix.

    Direct smelting process for nonferrous metal sulfide ores

    DESCRIPTION. This invention relates to a continuous process of directly smelting materials which contain non-ferrous metal sulfides. In the direct smelting of materials which contain non-ferrous metal sulfides such as concentrates or ores of lead copper zinc nickel cobalt or mixtures thereof a roasting reduction and smelting are effected at the same time in a reactor to produce either.

    Poly-metallic sulfide deposits are often major sources of copper zinc lead gold and silver ore. Some of these deposits also contain many various metals such as co- or by-products and impurities. Laboratories in mining sites are often required to analyze large number of samples per day. Therefore in order to determine multiple elements in ores simple and fast analysis technique with high.

    inorganic chemistry Why are the sulfide ores generally

    Jun 27 2018 The concentrated ore must be converted into a form which is suitable for reduction. Usually the sulphide ore is converted to oxide before reduction. Oxides are easier to reduce. Thus isolation of metals from concentrated ore involves two major steps viz. a conversion to oxide and b reduction of the oxide to metal.
