硫酸酸解攀西钛精矿技术研究

Abstract

Abstract: In order to improve the utilization of titanium resources in Panxi titanium concentrate，the process principle，technical parameters，and thermodynamics of acidolysis of Panxi titanium concentrate with sulfuric acid have been studied.Research results showed that，acidolysis ratio could reach more than 95% by optimizing the reaction factors，such as sulfuric acid concentration，acid/ore ratio，and curing time.In addition，if use 98%（mass fraction，same below） sulfuric acid to pre-mix with titanium concentrate，total heat release，aroused by dilution to the reaction concentration，was 1 397.5 kJ/kg，and the reaction was violent and dangerous.However，if use 92% sulfuric acid，the total heat release was 1 267.4 kJ/kg，which could heat the product to 271 ℃，the reaction was mild and total heat could totally meet the requirements of acidolysis reaction.

Key words: titanium concentrate, sulfuric acid, curing time, acidolysis temperature, acidolysis ratio
