摘要： A process for working up of a concentrate containing Cu, Zn, and precious metal including at least one of Ag or Au. In a first stage, the concentrate or the concentrate in modified form is leached for hydrometallurgically dissolving out the copper and zinc and leaving a residue containing the precious metal, and the leach liquor is separated from the residue. In a second stage, residue is subjected to a chlorinating sulfatizing roasting, and the roasted residue is leached with a selective solvent for the precious metal, e.g. aqueous NaCl, for dissolving the precious metal out of the residue.

摘要： A hydrometallurgical process for recycling the paste and electrolyte of junk lead-acid batteries begins by separating the paste and electrolyte from the junk batteries. The paste and electrolyte are then reacted to increase the lead sulfate content of the paste and reduce the acid content of the electrolyte. Excess liquid is then removed from the mixture of paste and electrolyte, after which the paste is mixed with an aqueous ammoniacal ammonium sulfate solution to dissolve a substantial portion of the lead sulfate from the paste. The remaining solid materials are then separated from the resulting pregnant lead solution, after which lead carbonate is precipitated from the pregnant lead solution by the addition of ammonium carbonate, ammonium bicarbonate or carbon dioxide. The precipitated lead carbonate is removed from the spent liquid and either converted to lead oxide by calcining, or mixed with sulfuric acid and then calcined or reacted with a chemical reducing agent to convert lead dioxide therein to lead oxide, and the lead oxide-containing material is then mixed with sulfuric acid in a second sulfating reaction to increase the lead sulfate content thereof. The resulting product is mixed with an aqueous ammoniacal ammonium sulfate solution to dissolve further lead sulfate therefrom. The resulting pregnant lead solution is separated from any solid materials remaining therein, after which lead carbonate is precipitated from the solution.

摘要： A method is disclosed for leaching finely divided lead sulphide bearing material to convert contained lead values to soluble lead acetate with concurrent conversion of sulphur values associated with the lead sulphide to an elemental state. The method involves forming a slurry consisting of the material dispersed in an aqueous medium containing free acetate ions and having a pH below 5.1. The slurry is reacted at a temperature of 60.degree. to 120.degree.C. with a free oxygen-bearing gas under a partial pressure of oxygen of 20 to 60 p.s.i. in order to convert lead sulphide to soluble lead acetate with concurrent production of insoluble elemental sulphur.

摘要： A hydrometallurgical process is used to recover lead from a lead-bearing ore concentrate. The lead-bearing ore concentrate is leached with a solution of cupric chloride in order to precipitate lead as lead chloride, produce elemental sulfur and substantially leave the balance of the ore concentrate sulfides in unreacted form. The residue of the cupric chloride leach is leached with a brine solution in order to solubilize the lead chloride to the exclusion of the balance of the residue. Thereafter, the lead chloride is crystallized from the brine solution. Elemental lead may be obtained by the reduction of the lead chloride crystals.The present process avoids air pollution problems inherent to smelting processes, allows for a high recovery of lead of 97% or greater and allows for the direct production of a high purity lead.
