  • NUCLEAR stone MINING OF PRIMARY SULFIDE

    A zone of secondary sulfide-enrichment separates the sulfide and oxide ores. Mine tailings in the camp contain primary sulfide, oxide and gangue minerals, secondary (supergene) minerals formed during weathering of the primary ore, and tertiary minerals formed by alteration of hypogene and supergene assemblages after deposition in the tailings

    The highest values of Se (130 to 1900 ppm) were found in massive Fe-Cu sulfide ores from Kondro, in particular the Cu-rich portions (average 1300 ppm Se). The average values of Se for the Othrys

  • What is Sulfide Mining? Mining Action Group

    Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water

  • Copper Ore Types: Sulfides versus Oxides Nasdaq

    2011-4-23 · There are two main copper ore types of interest, copper oxide ores and copper sulfide ores. Both ore types can be economically mined, however, the most common source of copper ore is the sulfide

  • Non-sulfide zinc deposits of the Moroccan High Atlas

    2020-7-17 · Non-sulfide zinc ores, also called ―calamines‖ or ―zinc oxides‖ were the main sources of zinc metal using calcination until the end of the nineteenth century. This process was energy-intensive, whereas the development of mineral processing techniques, like flotation has contributed to effectively smelt sulfide raw materials.

    2020-7-27 · 1. Pyritic ores with sulphur content greater than 18% can support a dust explosion. 2. Ignition temperatures of pyritic ores vary between 320oC and 365oC. 3. Minimum oxygen concentration to support a dust explosion is 13%. 4. No significant difference has been observed in explosion parameters of pyritic and pyrrhotitic ore.

  • Flotation of Copper Sulfide Ores PDF Free Download

    Some ores contain pyrrhotite and marcasite, which in many cases contaminates the concentrate. In the ores where pyrrhotite is present, copper concentrate can be as low as 16–20% Cu. Copper sulfide ores are disseminated and in some cases, would require fine re-grinding of the rougher concentrate (~25 m).

  • Geology and mineralogy of massive sulfide ores from

    Massive sulfide ores were collected from active and inactive vents and smokers and from mounds of the hydrothermal Jade field in the central Okinawa trough (Japan), which is a tectonically active intracontinental back-arc basin located in the northwestern Pacific.

  • Online analysis of minerals from sulfide ore using near

    Unfortunately, in case of sulfide ores, the method suffers from inadequate detection of lightweight materials such as sulfur and the common nature of iron, as iron is constantly present in several different minerals found in sulfide ores. Raman spectroscopy can be

  • US7736606B2 Process for the recovery of value

    A process for leaching a value metal from a base metal sulfide ore, comprising the step of leaching the ore with a lixiviant comprising a chloride, an oxidant and hydrochloric acid is disclosed. The leaching is controlled, by use of low concentrations of hydrochloric acid and a redox potential, to effect formation of hydrogen sulfide from the base metal sulfide ore.
