Document Type and Number:
WIPO Patent Application WO/2021/134385
Kind Code:
A1
Abstract:
An oxygen-enriched side blowing furnace smelting method for a secondary resource having arsenic and dispersed elements by adding ion and chlorinating agent respectively, comprising: adding a chlorinating agent accounting for 1-1.5% of the total weight of a furnace charge when the furnace charge is proportioned, preparing a material pressing block, and carrying out reduction smelting in an oxygen-enriched side blowing furnace. According to the method, the chlorine content in the raw materials is actively regulated and controlled to be within the range of 1-1.5%, and is 5-15 times of the content of the dispersed elements in the secondary resource. The method is particularly used for chlorinating and volatilizing the dispersed elements to achieve high-power enrichment and recovery of the dispersed elements, and has a remarkable resource utilization effect.
