Zinc oxide desulfurizer technical characteristics
1. zinc oxide desulfurizer, high efficiency, generally available in 95%,
2. short, easy to master process and operation, and covers an area of an area small,
3. Especially applicable to lead and zinc smelters. By-products of raw materials and the final disposal can combine with smelting system, need not purchased sorbent and set separately by-products processing facilities, is a process of zinc smelters clean production.
