Hydrometallurgy is a relatively recent development compared with pyrometallurgy. Leaching is the first prerequisite of any hydrometallurgical process. Hydrometallurgical processing involves leaching with a solution of ammonia. As a rule, the residue from the leaching operation is also treated for molybdenum
