desulphurisation of tailings

Environmental desulphurization of four Canadian mine ...

01/08/2000  Tailings' samples P and D have low sulphur contents. The gold contents of the two tailings is 0.56 and 0.23 ppm, respectively. One can observe in Table 2 that the main sulphide mineral in all of the tailings studied is pyrite. Sphalerite is a significant component in tailings G and M (1.24 and 1.74 wt.%, respectively), whereas chalcopyrite does not exceed 0.2 wt.% in any of the tailings ...

Environmental desulphurization of four Canadian mine ...

Environmental desulphurization is an attractive alternative for management of acid generating tailings. This process placed at the end of the primary process treatment circuit will reduce a large amount of the problematic tailings by concentrating the sulphide fraction. To produce desulphurized tailings, non-selective froth flotation is the most adapted method. The desulphurization level is ...

Desulphurisation of fine coal waste tailings using algal lipids . By Kudzai Godknows Chiodza. Abstract . The South African economy is an energy-driven economy which relies on coal to meet most of its energy demands. Coal mining has resulted in the generation of coal waste over 60 million tonnes, annually. Apart from the huge footprint of this waste, the sulphide minerals contained in the waste ...

A Feasibility Study on the Use of Desulphurized Tailings ...

Environmental desulphurisation is an attractive alternative for the management of acid generating tailings. Non selective froth flotation is the most commonly used method to produce desulphurized tailings, as shown from many previous works (McLaughlin and Stuparyk, 1994; Bussière et al., 1995; 1998; Benzaazoua et al., 2000a,b; 2002). This process can reduce the volume of problematic tailings ...

After desulphurisation, the pyrite-depleted material can be used to cover water saturated tailings with higher pyrite content (e.g. Lindvall Eriksson 2003, Lindvall 2005, Mueller 2012), whereas the pyrite enriched material has to be deposited separately under an engineered dry cover or water cover.
