FREMGANGSMAATE VED UTVINNING AV SINK FRA RESTERENDE STERK SVOVELSUR LOESNING FRA SINKELEKTROLYSE SAMT ANORDNING FOR UTFOERELSE AV FREMGANGSMAATEN

摘要

Process for the recovery of the zinc contained in the residual solutions obtained after electrolytic deposition by fixing the zinc (none of the other metals present in the solution being included in said complex), in the form of a complex by adding of a alkaline metal halide (sodium chloride preferred) to the residual solution adjusted to a low acidity, for example, by dialysis. The process permits the almost total recovery of zinc, and a large part of sulfuric acid.
