VERFAHREN ZUR RÜCKGEWINNUNG VON NICHTEISEN-METALLWERTSTOFFEN, INSBESONDERE NICKEL, KOBALT, KUPFER UND ZINK, DURCH SCHMELZSULFATIEREN UND SCHMELZBESCHICHTUNGSSULFATIEREN, AUS ROHSTOFFEN, DIE DIESE METALLE ENTHALTEN.

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.
