ABSTRACT:
Process and apparatus for the electrowinning of metals from sulphide ores wherein a sulphide ore is initially leached in a water soluble sulphide solution, alkali is then added, and the resulting solution is electrolyzed so as to deposit metal at the cathode and obtain water soluble sulphide as a by-product. The process is particularly suitable for obtaining antimony from stibnite.
