Leaching Mining Fundamentals. Leaching is a chemical process in mining for extracting valuable minerals from the ore. Leaching also takes place in nature where the rocks are dissolved by water. Nov 01, 2002 In this research work the sulfuric acid leaching of a typical Turkish chromite concentrate was studied. The following was concluded considering the experimental results 1. In the absence of perchloric acid, the maximum chromium extraction was about 58% under the conditions of 175 C, 70 vol% H 2 SO 4 (81.4 wt.%) and 2 h.
