description A process for treating waste includes reacting a feedstock in a reactor to form an effluent. The feedstock is part of a reaction mixture that includes sulfuric and nitric acid. The effluent is separated into a liquid fraction and a solid fraction. Heavy metals such as arsenic, cadmium, cobalt, mercury, molybdenum, and/or selenium are removed from the liquid fraction to form a cleaned liquid fraction. The reaction mixture, excluding solids, includes no more than 7.5 wt % of the total of the first oxidizing acid and the nitric acid.
