Oct 24, 2019· The results of the mineralogical examination of old sulphide and oxidized gold ore tailings of a mining and processing plant in the Krasnoyarsk Territory are presented. Secondary mineral forms of antimony, namely, antimony bloom Sb2O3 and tripuhyite FeSBO4, as well as iron are found. Gypsum in the waste is a newly formed phase, undetected in the initial ore, revealed in sulphide and mixed ore ...

Located 560 kilometres north of Adelaide, Olympic Dam is one of the world's most significant deposits of copper, gold, silver and uranium. Olympic Dam is made up of underground and surface operations and operates a fully integrated processing facility from ore to metal.
The tailings are placed in a tailings storage facility, where the embankments are constructed using the coarser material from the grinding plant. For oxide ore, the processing facilities will consist of a series of unit operations, such as carbon adsorption, acid wash, elution, carbon regeneration, electro-winning, filtration and drying, to ...

Jun 29, 2018· Tailings from the ore processing facility will be treated to reduce the cyanide levels and stabilize mercury, and would then be transported in a pipeline to the Tailings Storage Facility (TSF) built in the Anaconda Creek valley. The TSF will be constructed by building a tailings dam across the lower part of the valley.
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.
The tailings are often treated with lime to neutralize acids and precipitate heavy metals as insoluble hydroxides before pumping to the dam. Such treated tailings may be thickened, and the overflow, free of heavy metals, returned to the mill (Figure 16.9), thus reducing the water and pollutant input to the tailings dam.

The ground ore is then floated to produce a gold rich copper concentrate for filtration and sale to overseas smelters. Flotation tailings are then leached for further gold recovery. The ore processing rate is approximately 35 million tonnes per annum. Typical head grade is approximately 0.8 gram per tonne gold and 0.11 per cent copper.
historic gold tailings dams in the Witwatersrand area of South Africa is being investigated. The objective is to recover uranium and residual gold from the tailings, as well as to oxidize the sulphides to eliminate long term environmental liabilities associated with acid mine drainage. The tailings from the re-processing plant will be re-
