摘要
process for processing complex collective contracts with poor sulphides content of pb, cu, zn, bi, mo, cd and precious metals according to the invention provides lesierea azotica in two steps at 95.105 degree c to solubilise cu, zn, fe, bi,mo and cdsi separation in which a residue plumbos collect precious metals and which is still pirometalurgicuzual separation process for each element.the solution obtained is separated in every element, and the solution obtained is separated bi, mo and fe, by precipitation with zn (oh2), zno, naoh or co3na2 at ph = 1.5.2.5, mo being separated by the resulting solution; with naoh, and bi by dissolution in acid solution, and left after coprecipitarea with whitewash and solution to lutie acid....
