Abstract

Improvements introduced in the object of the main patent no. 471.012 by: procedure for obtaining lead salts from lead sulfate, characterized in that the aqueous suspension of lead sulphate is transformed by an alkali, to tribasic sulfate of lead, which once purified from alkaline sulphate by washing, it is treated at 10-100º c, with the stoichiometric amounts of an organic or inorganic acid and an alkaline hydroxide, either previously mixed or separately, said stoichiometric amounts according to the desired final product.
