Research and Application of Oxygen Enriched Iron Removal Process Technology
The iron removal process is a crucial link in the oxygen pressure leaching process of Danxia Smelter,and it is very important to adopt an efficient and stable iron removal purification process.To accelerate the reaction process of iron removal and germanium removal,a large amount of copper sulfate needs to be consumed as an auxiliary additive,and the extensive use of copper sulfate will increase the production cost of the factory.To meet the requirements of capacity expansion,it is necessary to optimize and improve the oxygen enriched iron removal process and technical means.By systematically analyzing the process flow and application of oxygen pressure leaching needle iron ore method for iron removal,this paper proposes how to introduce oxygen enrichment in the treatment of high concentration impurity solutions and replace traditional compressed air as the reaction gas,thereby improving the reaction rate and neutralizing agent utilization rate,optimizing energy consumption configuration,and reducing the dependence of the reaction process on copper sulfate.
