Oxidation nke Sulfide mineral

Otu n'ime ọrụ ndị bụ isi nke potassium permanganate na nchịkọta mkpokọ bụ oxidation nke mineral sulfide nke a na-ahụkarị n'ime ores ọlaedo. Sulfide, dị ka pyrite na arsenopyrite, na-ejikarị mkpụrụ ọlaedo eme ihe, na-egbochi ihe na-amịpụta ihe ka ọ ghara imetụ ọlaedo ahụ aka. Potassium permanganate na-eme ka mineral sulfide ndị a dị ọcha site na mmeghachi omume redox. Usoro oxidation a na-agbaji matriks sulfide, na-ekpughe mkpụrụ ọlaedo ndị a nwụchiri.
