OBTENTION OF METAL SOLUBLE SALTS FROM SLAG GRANULATED IN WATER, PRODUCT RESULTING FROM THE PROCESS FOR OBTAINING BULLION LEAD.

摘要

The present method refers to the recovery of metal soluble salts by a waterwash, from slag granulated in water at pressure produced from the mineral fusion for obtaining bullion lead. Said method comprises a plurality of steps such as the sulphuric acid digestion, solubilisation, filtration and recovery of heavy metals. The resulting solid mainly contains gold, silver and lead, these are recovered again by the fusion of lead minerals; the product may be used as fertiliser once the digestion of the slag was performed.
