Behaviour of Metals during Bioheap Leaching at the Talvivaara Mine, Finland [PDF]
, 2018 The behaviour of base metals Ni, Zn, Cu, Co, Fe, and Mn, potentially toxic metals Pb, Cr, and Cd, and the radioactive elements, U and Th, in the Talvivaara mining process, Finland has been studied by tracing metal concentrations from the black schist ore,

Enhancing gold recovery by bioleaching of chalcopyrite low grade ore [PDF]
, 2005 The conventional flotation can't provide fair results when applied to very low grade ores or to "refractory" ores. This class includes intimate and nonuniform mineral associations, with partialy oxidized minerals and high secondary mineral content and ...

Using of Chroococcus SP. to Treat Polluted Water with Cadmium & Nickel [PDF]
, 2012 Chroococcus sp. was exposed to different concentrations 0.3, 0.5, 1, 2, 3, 4, 5, 6 and 7 ppm, from cadmium and nickel. The results revealed that the ability of the alga to remove cadmium and nickel was increased with the increase of the metal ...

Formation of water-soluble metal cyanide complexes from solid minerals by Pseudomonas plecoglossicida [PDF]
, 2017 A few Pseudomonas species are able to form hydrocyanic acid (HCN), particularly when grown under glycine-rich conditions. In the presence of metals, cyanide can form water-soluble metal complexes of high chemical stability.
