预氧化在盐酸法制取人造金红石中的作用

Function of Fore-Oxidation on Preparing Synthetic Rutile by Hydrochloric Acid Leaching

摘要:

论述了预氧化机理、酸浸反应机理和细化机理，并通过攀枝花钛铁矿与预氧化矿在1000t／a生产装备上的对比试验，考察了两种矿对酸浸后粗金红石品位及产品细料率的影响，阐明了预氧化有提高粗金红石品位、降低产品细料率的作用。

Abstract:

The theory of fore-oxidation, the reaction theory of acid leaching and the theory of attenuate are discussed. Through comparing different effects of Panzhihua ilmenite and fore-oxidized ore on the grade of thick synthetic rutile and the pulverization rate of product after acid leaching, it is described that fore-oxidation has functions of improving the grade of thick synthetic rutile and reducing the pulverization rate of products.
