In one method, a zinc concentrate is leached as elemental sulfur and other by-products are stripped from the surfaces of the particles in the concentrate by means of a grinding machine such as a ball mill. The ferric ion consumed by leaching is regenerated for recycled use by introducing oxygen into the post-leaching solution flowing through feed pipes.
The invention also relates to an apparatus for treating zinc concentrates, said apparatus comprising a smelting furnace and a slag treating furnace arranged in connection therewith. A partition wall separates the 10 gas spaces of the smelting and slag treating furnaces from each other, and another partition wall separates ...
