  • PyriteGold Recovery in Copper Rougher Flotation Tailings

    recovered in Test 1. Test 2 showed the highest gold recovery 45%, due to higher pyrite recovery 45% Table 3. When the reground product of Test 3 was preaerated before flotation, about 33% of gold was recovered at an improved grade 2.3 g/t. Also, the highest gold

  • Release of Heavy Metals from the Pyrite Tailings of

    To provide the basic information about the release of heavy metals from the pyrite tailings of Huangjiagou pyrite mine, the pyrite tailings were investigated through a series of batch experiments under different initial pH of extractant, temperature, liquidsolid LS ratio, and soaking time conditions. Moreover, calcium carbonate was added in the pyrite tailings to determine the reduction

  • Release of Heavy Metals from the Pyrite Tailings of

    The acid rain promotes the release of heavy metals and causes more released amounts of heavy metals from the pyrite tailings of the Huangjiagou pyrite mine. Thus, the serious pollution of heavy metals appeared in this study area. At present, the pH of rain

  • Pyrite Tailings Recovery by Flotation

    CONDITIONING. FLOTATION. THICKENING AND FILTERING. LABORATORY TESTS. Pyrite has long been used as a source of sulphur, and its recovery as a byproduct from the flotation of certain base metal ores is a well established practice. Large tonnages of mill tailings which have accumulated as a result of various milling operations frequently contain significant amounts of pyrite.

    The latter are finely ground rock particles generated during the processing of ore materials and separation of target metal minerals, and are highly reactive because of their small particle size and content of reactive minerals, such as pyrite FeS 2. Mine tailings may contain base transition metals, such as iron, copper, nickel and zinc, in relatively high concentrations, and also occasionally

  • Mine Tailings Waste Leaching & Groundwater Contamination

    A total of 51,191 million tons of overburden, waste rock, and tailings was generated by the metalore and nonmetal mineral mining industries during the period 19601977. Of this total, approximately 40 percent was generated by the copper mining industry alone.

  • Treatment of Old Pyrite Flotation Tailings for Recovery of

    A sample of old pyrite flotation tailings from the concentrator contained 11.4% sulfidic iron, 14.5% sulfidic sulfur, 0.26% copper, 0.22% zinc, and 0.67 g/t gold. Pyrite was the main sulfide mineral 31%. The gold recovery from the unoxidized flotation tailings was 50%. Recently, it has been proposed to

  • CLEAN TAILING RECLAMATION: REVEGETATION OF MILL

    Cleaning or reprocessing of tailings to remove residual pyrite and heavy metals was evaluated as a reclamation technology. Tailing materials from three sites an active copper mine, a Superfund site, and an abandoned tailings pond were collected and reprocessed. Successful mineral separation resulted in a small amount of metal sulfide concentrate and a large volume of reprocessed tailings that had a low metal sulfide
