由矿石原料生产铅的传统流程包括精矿的焙烧和还原熔炼,用此法生产的铅占世界铅产量的95%以上。世界铅产量的35%以上来自二次铅原料,在苏联由二次铅原料生产的铅约占26%。二次铅冶炼的主要原料是蓄电池残屑,化学工业、合金生产、轧制车间和电缆工业的废料等。在苏联的冶炼厂中,二次原料生产铅的主要方法是鼓风炉还原熔炼。全世界约75%的二次铅原料用此法处理(苏联为80%以上)。但有些冶炼厂,把二次铅原料和矿石一起给
The traditional process for the production of lead from ore raw materials involves the roasting and reduction smelting of concentrates. Lead produced by this method accounts for more than 95% of the world’s lead production. Over 35% of the world’s lead production comes from secondary lead raw materials, and about 26% lead is produced from secondary lead raw materials in the Soviet Union. Secondary lead smelting is the main raw material for battery scrap, chemical industry, alloy production, rolling mill and cable industry waste. In the Soviet Union smelter, the main method of secondary production of lead is blast furnace smelting reduction. About 75% of the world’s secondary lead raw materials are treated this way (over 80% in the Soviet Union). But some smelters, the second lead raw materials and ore to give
