At the Old Tailings Dam (OTD), Savage River, Western Tasmania, 38 Mt of pyritic tailings were deposited (1967 to 1982) and have since been generating acid and metalliferous drainage (AMD). Mineral chemistry analysis confirmed high concentrations of refractory cobalt in pyrite (up to 3 wt %). This study sought to determine, through a series of bench scale tests, if Co could be …

Other sources of magnetite iron ore include metamorphic accumulations of massive magnetite ore such as at Savage River, Tasmania, formed by shearing of ophiolite ultramafics. Another, minor, source of iron ores are magmatic accumulations in layered intrusions which contain a typically titaniumbearing magnetite often with vanadium.

In this work, we proposed a method for biohydrometallurgical processing of mining (old pyritic flotation tailings) and metallurgical (slag) wastes to recover gold and other nonferrous metals. Since this processing allows the removal of toxic metals or at least decreases their content in the solids, this approach may reduce the negative environmental impacts of such waste.

Jun 01, 2015· Pyrrhotite is the major sulfide mineral in tailings deposits at the Nickel Rim and Sherridon mines, but was not observed at Greens Creek. The crystal structure of pyrrhotite is disordered with vacancies related to the Fe(II) deficiency, which can be charge-compensated by Fe(III) (Jambor, 2003, Blowes et al., 2014).

The Savage River operation is set to continue until 2034. History. Magnetite mineralisation was discovered at Savage River in 1887, however, for many years, interest centred on the copper and gold potential of the deposit. Exploration in 1956 included ground and air magnetometer surveys, with diamond drilling in 1957 and 1959.

The W/R of river water is unknown but temporarily fixed as 3000 because the water–rock reactions between flowing river water and the river basement generally proceed at high W/R. The groundwater composition is taken from the modeling results of reactions between rock and the O 2-bearing initial fluid at W/R of 1000 and 5 °C.
