Sepg. copper from ammonium molybdate - comprises precipitating copper ions using sulphide precipitating agent

摘要

A process for sepg. out Cu impurities from an aq. ammonium molybdate soln. includes precipitating the Cu ions as Cu ions, as Cu sulphide, using a sulphide agent. agent consists of a thio urea material, added in max. stoichiometric amts. to the ammonium molybdate soln.. The soln. is then harmed, - -100 deg.C.
