Pyrite Tailings Recovery by Flotation

silver bearing minerals along pyrite to the tailings. Thus, the flotation tailing slurry sample of 1 tonne solids was collected. The slurry colleted was filtered and dried in an electric oven. The dried solids were thoroughly mixed and representative samples were prepared using standard sampling methods. RESULTS AND DISCUSSIONS

Occurrence of sulfate

When the tailings from a pyrite mine are exposed to oxygen and water, sulphides oxidise to sulphates, the pH falls markedly due to the formation of sulphuric acid, and the pollutants solubilize (Förstner & Wittmann, 1983). ... 4-6, 6-8, 8-10, 10-12 mm in depth) and sampling the underlying soil at different depths to 101 mm (12-14, 19-21, 29-31 ...

A part of the crude pyrite refuses were processed for the production of sulphuric acid, oleum and Cu sulphate, by roasting and SO 2 recovering. This process was enhanced by catalytic improvement (Morales, 1986). Two tailing ponds were built as part of the Almagrera project, one for pyrite cinders and the other for the flotation plant refuses.

Table 2 is a summary of the sampling results. Sample # 355554 contains 2.29% Cu 0.39 07o Ni, .2 g/t Au, 0.54 g/t Pt, l .964 g/t Pd. The average of the 9 tailings samples (35554 to 355562) is .4207o Cu, .2207o Ni, 0.35 Ig/t Pt, 0.737 g/t Pd. The results are near economic and therefore additional sampling is required. A program

GEOCHEMICAL CHARACTERISATION OF PROCESS

Autoclaved characteristics of pyrite tailing are studied mixed different materials by different curing condition. The results show that compressive strength of pyrite tailing autoclaved sample is 0. Pyrite tailing autoclaved sample acquires a higher compressive strength mixed with lime. But effect of gypsum is few on compressive strength of pyrite tailing lime autoclaved system.

May 29, 2012· The field data were compared to predictions from simulations of pyrite oxidation using a 1-D numerical model. The simulations' estimates of the amount of Fe and S released over a seven year period (52 kg and 178 kg, respectively) were in reasonably good agreement with those obtained by analysing the tailings (34 kg and 155 kg, respectively).

mineral assemblage in the tailings is dominated by pyrite, with lesser amounts of chalcopyrite, bornite, enargite, molybdenite, digenite, chalcocite, and covellite. At CT1 (actual spitting point during sampling, October 2002) and CT2 which represents freshly deposited tailings, the pyrite grains are fresh and do not show signs of alteration (Fig.
