摘要

Procedure for obtaining high-scale pure lead sulfate, particularly suitable for the production of highly dispersed lead pigments, by leaching with alkaline chloride solution from lead materials characterized by the fact that the sodium chloride-chloride solution of lead obtained, filtered, is reacted with 0.1 - 0.25 mol of soda and then with 0.5 - 0.8 mol of caustic soda solution every 1 mol of lead, and the basic lead chloride finely granular precipitate is transformed with sulfuric acid, in a manner known per se.
