Abstract

127,641. Elmore, F. E. May 8, 1917. Sulphur.-In a process for extracting lead and zinc from. lead-zinc sulphide ores, concentrates, and the like, involving the treatment of the ore &c. with sulphuric acid, the evolution of sulphur dioxide or sulphuretted hydrogen is avoided by treating separate batches of ore &c. with strong and somewhat weaker acid respectively, the sulphur dioxide from the strong-acid batch being lead into the weak-acid batch when sulphur is precipitated.
