The company mainly uses the patented technology of the company's reverse expansion rotary kiln to recover valuable metals from low zinc and tin materials. The smelting waste materials in local and surrounding areas are comprehensively treated by the high temperature reduction and volatilization process of Welz method, and valuable metals such as zinc and tin are recovered.

With the increase of domestic non-ferrous metal production, the consumption of raw materials also increases. The gap of raw material supply in domestic mines is increasing year by year. The supply of concentrate can not meet the demand of smelting enterprises' capacity. Therefore, it is necessary for smelting enterprises to carry out technological innovation and make full use of various non concentrate raw materials to make up for the gap of concentrate raw materials. According to the investigation of raw materials around Yunnan production base, there are a large number of low zinc materials in Yunnan, Guizhou and Sichuan provinces. In addition, there are also some low zinc materials in neighboring Vietnam and Myanmar in Yunnan, and the main consumption is China. There are many large zinc smelting and steel enterprises in Yunnan, which require a lot of zinc oxide produced by rotary kiln. Therefore, it has good production conditions and broad market space to use rotary kiln to treat zinc containing materials in Yunnan.

1. The rotating system deals with 30000 tons of hazardous waste containing zinc (10% zinc) annually, and the zinc oxide ore with the treatment of 30000t (10% zinc). The recovery of zinc metal is about 6000 tons, and the annual output of zinc oxide is 12000 tons.
