PROCESS FOR RECOVERING NON-FERROUS METAL VALUES, ESPECIALLY NICKEL, COBALT, COPPER AND ZINC, BY USING MELT AND MELT COATING SULPHATION, FROM RAW MATERIALS CONTAINING SAID METALS

摘要

The invention relates to a process for recoveringthe non-ferrous metal values nickel, cobalt, copper,zinc, manganese and magnesium from material containingsaid metals, by converting the non-ferrous metal valuesinto sulphates by using melt and melt coating sulphationand recovering them as metal compounds as a processentity formed around a melt and melt coating sulphation.
