<p>The pH of the solution is raised to 7-10 and treated with a sulphide ion liberating agent in quantities which are sufficient to precipitate all the copper present in the soln. The precipitate is separated from the soln. and the soln. is then saturated witht he sulphide ion liberating agent and acidified to a pH below 3.5. whereupon molybdenum sulphide is precipitated.</p> |
