Bioleaching of highly concentrated arsenic mine tailings

Sep 08, 2014· Therefore, a systemic study on As leaching behavior from mine tailings with high As level is necessary. In this study, As bioleaching using A. ferrooxidans was conducted on precious metal mine tailings containing highly concentrated As. The As bioleaching efficiency was evaluated according to changes in three experimental conditions (i.e

Bioleaching of cobalt from Cu/Co-rich sulfidic mine

Nov 01, 2020· The leaching dynamics of Cu from the tailings concentrate seem to reach a dissolution plateau earlier than Co . For the bulk tailings, Co and Cu leaching dynamics showed similar trends (data not shown). Thus, Cu in the tailings concentrate may be more refractory than Co for dissolution (Schirmer et al., 2017). The large content of the silicate

Leaching (metallurgy) Wikipedia

Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within into soluble salts while the impurity remains insoluble. These can then be washed out and processed to give the pure metal; the materials left over are commonly known as tailings.Compared to pyrometallurgy leaching is easier to perform, requires less energy and
