Abstract

Procedure for obtaining basic salts of lead from low-grade by-products, characterized by subjecting the extractor to a purification of SO4Na2 which is carried out when this impurity reaches a degree of 30-50 g/liter (for a process temperature of 0-100º C) this purification is carried out by adding a calcium chloride solution of 8.5 to 25.1% of richness, and choosing within those limits that which corresponds stoichiometrically to the richness in sodium chloride of the extracting solution; Once the precipitated SO4Ca2H2O has been eliminated, the Ca ++ that remains in solution - due to the solvent effect of NaCl on SO4Ca.2H2O- is eliminated by the addition of sodium carbonate until reaching a pH of 8.1 to 9.1, maintaining the maximum limit of Ca ++ in the extracting solution below 0.030 gr/liter for temperatures from 0 to 50º C, and 0.030 gr/l for temperatures from 50 to 100º C; Once the Co3Ca is eliminated, the pH is adjusted from 2 to 7 with hydrochloric acid.
