A process method for producing lead calcium cerium alloy on the basis of a waste lead grid mesh of a waste lead-acid storage battery belongs to the field of integral recycling of waste lead-acid storage battery. The process comprises the steps of performing low-temperature melting on the waste lead grid mesh to remove copper, refining to remove impurity, selectively removing antimony and arsenic,adjusting tin content, adding calcium aluminum and rare-earth cerium for alloying, and casting ingot. The indexes such as tensile strength, density, hardness and corrosion resistance of the produced lead calcium cerium alloy are basically consistent with those of lead-based alloy prepared by original electrolytic lead, and the application requirement of storage battery grid alloy is met. The process method has the advantages that the process is simple, is convenient to operate and is high in production efficiency, valuable metal tin in the waste lead grid mesh is effectively utilized, the production cost of lead alloy preparation is reduced, meanwhile, no smoke and no favor are generated during the antimony and arsenic removal process, and the working environment is favorable.
