Process of 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 recovering non-ferrous metal values such as nickel, cobalt, copper, zinc, manganese and magnesium from material containing said metals, by converting the non- ferrous metal values into sulphates by using melt and melt coating sulphation and recovering them as metal compounds by a process entity based on a melt and melt coating sulphation.
