A method for the manufacture of insoluble lead anodes, with low segregation of the constituent elements of the anodic alloy for the electrowinning of metals, free of buckling, used in electrolytic processes, which comprises: Obtaining a continuous plate (4) of lead or lead alloy 10 to 30 mm thick by 900 to 1,100 mm wide by means of a continuous casting process; Cut the continuous plate (4) according to a determined length obtaining a pre-plate (6) that will give the length of one or more plates of the anode (8); Roll the lead or lead alloy pre-plate (6) using a cold rolling mill (7) to a thickness of 6 to 12 mm, keeping the cold rolling temperature of the pre-plate under 60° C., obtaining the anode plate(s) (8); Remove the anode plate (8) from the rolling mill (7); Weld (12) a copper bar (10) to the upper end of the anode plate (11).

PERIPHERAL COATING PROCESS OF THE COPPER CONDUCTIVE BAR FOR THE MANUFACTURE OF ANODES, USED IN THE PROCESSES OF ELECTRO-OBTAINING OR ELECTRO-REFINING OF METALS
B24C 3/32 - Abrasive blasting machines or devicesPlants designed for abrasive blasting of particular work, e.g. the internal surfaces of cylinder blocks
A method for assembling anodes used in electro winning processes that increases corrosion resistance. The method includes pre-coating the copper bus bar, introducing the copper bar into a mold, peripherally coating the copper bar with a lead-antimony alloy, moving the copper bar to the assembly table, filling a slot in the copper bus bar with a lead-bismuth alloy, introducing the end of a plate into the slot while the lead-bismuth alloy is in a liquid state, and once the lead-bismuth alloy in the slot has solidified, applying reinforcement solder.
