Jul 10, 2014· The leaching behavior of both the silicate and the spinel phases was investigated in the current study. Before the test, a chromite lump was polished by polisher and several types of abrasive paper to get two smooth flat surfaces. 100 mL 80 wt.% sulfuric acid and 1 g oxidant were mixed in a glass beaker on an automatic temperaturecontrolled electric heater, and the heating of the solution .
J. Hammerschmidt, ... A. Charitos, in Gold Ore Processing (Second Edition), 2016. Sulfuric Acid Plant. The sulfuric acid plant can be divided into three main sections: drying and adsorption, SO 2 converter with gastogas heat exchangers and tail gas scrubber. The plant uses the 3 + 1 doubleabsorption system.
