Page view

On May 6, the special Research and Demonstration Project of Key Environmentalfriendly Sb Smelting Process passed the technical review by experts group and recommended as 2013 Hunan major science & technology projects.

In view of serious environmental pollution and excessive energy consumption for Sb smelting in China, the special research was conducted based on the Key Technology Demonstration Project of 20kt/a environmentalfriendly Sb Smelting Operation built by Xikuangshan Shanxing Antimony Co., Ltd, “the Sb capital of the world” and through the developed technologies such as oxygenenriched Sb concentrate volatilization, oxygenenriched crude antimony oxide reduction bath smeltingkey technology and equipment, hightemperature highconcentration Sbcontaining gas waste heat recovery key technology and equipment, hightemperature highsulfur Sbcontaining gas dustremoving key technology, lowconcentration SO2 treatment. After the project implementation, it is expected that annual recovery and heavy metals discharge reduction will be up to 70t As, 60t Pb and 460t Sb.
