2021-10-7 · Abstract Historic sulfidic mine waste material poses both an economic opportunity and an environmental threat (e.g., acid mine drainage). Due to low metal content in the mine waste and complex mineralogy, metal extraction of metal of interest is challenging. The Plombières tailings pond in eastern Belgium was selected as a case study to determine the

Leaching - Mining Fundamentals. Leaching is a chemical process in mining for extracting valuable minerals from ore. Leaching also takes place in nature, where the rocks are dissolved by water. Post leaching, the rocks are left with a smaller proportion of minerals than they originally contained. The leaching process in mining is carried out ...

2021-2-18 · Three different mine tailings (sites A, B and C) from Cobalt Mining Camp were collected and characterized. Preliminary chemical leaching tests were conducted with inorganic acids (HCl, H 2 SO 4 and HNO 3) to solubilize Co and Ni at different concentrations (0.01–0.5 N). The influence of the number of the leaching steps on the recovery of Co ...
