    Lead metallurgy process - pyrometallurgical lead smelting (three-stage furnace lead smelting method)

    Yuguang three-stage furnace lead smelting method The main process of Yuguang three-stage furnace lead smelting is bottom blowing furnace oxidation desulfurization, bottom blowing furnace reduction, and fuming furnace recovery of zinc. It was industrialized and applied in 2010. Cancel the blast furnace, eliminate metallurgical coke, and achieve direct reduction of liquid slag. Together with the original oxygen enriched bottom blowing furnace oxidation section, form a complete industrial production system for direct reduction of liquid slag. The specific technical solution is to mix lead concentrate, limestone, quartz sand, etc. and send them to an oxygen bottom blowing furnace for smelting, producing crude lead, liquid slag, and dusty flue gas. Liquid high lead slag is directly fed into the horizontal reduction furnace, with natural gas and oxygen supplied by the bottom spray gun, and a feeding port provided at the top for adding coal particles and stones. The slag is discharged intermittently. The partial oxidation combustion of natural gas and coal particles releases heat, maintaining the temperature required for the reduction reaction. Under gas stirring and mass transfer, the reduction of high lead slag is achieved.

    Lead acid battery recycling and processing technology

    Lead acid battery recycling and processing technology 当前，废铅酸蓄电池的处理工艺流程主要有三种： 第一种是将废铅酸蓄电池进行去壳倒酸等相关处理之后，进行火法混合冶炼。这种方法的优点在于操作简单，能够高效地得到铅锑合金，但同时也存在能耗高、污染重的缺点。火法冶炼过程中会产生大量的废气、废水和废渣，对环境造成严重影响。 第二种方法是将废铅酸蓄电池进行破碎分选，分出金属部分和铅膏，两者分别进行火法冶炼。这种方法相对于第一种方法来说，能够更好地分离出有价值的金属和铅膏，提高了回收利用率。同时，由于分别进行冶炼，也能够减少能耗和污染。但是，破碎分选过程中会产生大量的噪音和粉尘，对操作人员的健康也造成一定的威胁。 第三种方法是在第二种方法的基础上，对铅膏部分进行脱硫转化，然后再进行火法冶炼。这种方法相对于第二种方法来说，能够更好地处理铅膏部分，提高了铅的回收率，同时也减少了硫的排放，对环境的影响也更小。但是，脱硫转化过程中需要加入一定的化学药剂，可能会产生新的污染物。
