Title: Recovery of high-purity silver from copper-electrolytic precipitate
Inventor: ABE TATSUICHIROU
IPC: C25C1/20
Filed: 1983-08-04
Abstract: PURPOSE:To recover high-purity copper from a copper-electrolytic precipitate in a high yield by a method in which the copper-electrolytic precipitate is leached with chlorine gas to form AgCl residues, the AgCl residues are reductively melted to form rich lead, the rich lead is oxidized by oxygen to form crude silver, and the crude silver is cast in anode for electrorefining. CONSTITUTION:Copper electrolytic precipitate or copper-deprived precipitate in the electrorefining process of copper is slurried with a 1-5 N aqueous solution of the chloride (e.g., NaCl, MgCl2, etc.) of the I group or II group metal in the periodic table, and chlorine gas is blown into the slurry at 60-80 deg.C to obtain AgCl residues containing about 40-43% silver. An adequate reducing agent and an adequate brine-forming agent are added to the AgCl residues, and the AgCl residues are melted at 1,100-1,200 deg.C to form an about 70% Ag-containing rich lead. An oxidizer is blown into the work lead at 1,100-1,300 deg.C to raise the silver content to about 99% or more, the scum formed is removed, and the molten silver is cast into a crude silver plate. The crude silver plate is subjected to electrorefining to obtain a purified silver of a high purity of about 99.999% or more.

Title: Manufacture of plate for lead acid battery
Inventor: SHIMA TOSHIAKI
IPC: H01M4/20
Filed: 1980-10-13
Abstract: PURPOSE:To successively form plates for a lead acid battery which have long life through simple process, by packing a paste in a base body prepared by fixing a lead (alloy) grid to a synthetic resin frame, and fusing a mat to the former frame. CONSTITUTION:A grid 18 prepared by casting lead (alloy) is attached to a frame 20 made of a synthetic resin, thereby forming a base body 22. The base body 22 is packed with a paste 31 made of a lead oxide prepared by kneading lead powder with sulfuric acid and water. The base body 22 packed with the paste 31, after it is semi-dried, is covered with an acid resistant mat 45 made of glass fiber or the like, is passed between hot rollers 50 and 50', and is placed between a hot mold so as to make the mat 45 to be fused to the frame 20, thus a plate is formed. By the means mentioned above, the process of the formation of the plate is simplified, and the work efficiency is enhanced. Besides, the life of the plate can be maintained for a long period of time, since the mart 45 is firmly attached to the base body 22, and the separation of the active material is prevented.
