General Manager
Guizhou Cenxiang Resource Technology Co., Ltd.
Guizhou Cenxiang Resource Technology Co., Ltd. is located in the Cenxiang Economic Development Zone, Cengong County, Qiandongnan Prefecture, Guizhou Province. The company has established an annual production capacity of 130,000 tonnes of lead ingots and can process up to 200,000 tonnes per year of spent lead-acid batteries and other lead-containing wastes. Through continuous process upgrades and technological innovation, the company has maximized resource recycling efficiency, while achieving industry-leading performance in energy consumption control and flue gas emission indicators.
Asian Metal: Welcome, Mr. Wei, and thank you for joining our interview. First, could you please give us a brief introduction to your company?
Kun Wei: Guizhou Cenxiang Resource Technology Co., Ltd. is located in the Cenxiang Economic Development Zone, Cengong County, Qiandongnan Prefecture, Guizhou Province. In 2018, we completed and commissioned a recycling project with an annual processing capacity of 200,000 tonnes of spent lead-acid batteries. At present, the company has reached a production scale of 130,000 tonnes per year of lead ingots and can process 200,000 tonnes annually of spent lead-acid batteries and other lead-containing wastes. Our core strengths are mainly reflected in three aspects. First, in the pretreatment stage, spent lead-acid batteries are crushed and separated, with lead paste and grids treated separately. The lead paste undergoes a pre-desulfurization process to produce lead oxide, while the lead grids are processed using low-temperature smelting technology, enabling maximum recovery of valuable metals such as antimony and tin and achieving efficient resource recycling. Second, benefiting from the low-temperature smelting process, our overall energy consumption level is relatively low. Third, we have adopted a self-developed “dual-bath smelting furnace,” which achieves industry-leading standards in both energy consumption control and flue gas emission performance.
