The invention relates to a method for low-temperature smelting of regenerated lead and belongs to the technical field of preparation of regenerated lead. According to the method provided by the invention, an alkaline environment is provided by sodium carbonate, regenerated lead raw material and / or lead ore powder are / is taken as a lead source, carbon is taken as a reducing agent, alkaline smelting is performed at the temperature of 800-1100 DEG C, three products, namely crude lead or precious lead, smelting slag and smoke gas are produced, most of gold, silver and other precious metals enter crude lead or precious lead, crude lead produced by smelting is settled to the bottom for discharge, sulfur enters the smelting slag in the form of sodium sulfide, after water leaching of the smelting slag, filtrate is concentrated and crystallized in steps to obtain sodium carbonate and sodium sulfide products, and after dedusting of the smoke gas, smoke dust returns into the raw material, and waste gas can be directly discharged after being absorbed by lye. The technical scheme provided by the invention has the advantages of low energy consumption, low cost, environmental friendliness and the like, and further has significant economic benefits and social benefits.
