conditions, the leaching ratios of Ti and Fe are 1.07% and 95.5%, respectively. As a result, Ti and Si are still in the slag, and the other elements are enriched in the lixivium. In addition, the synthetic rutile with the grade of over 90% is obtained by calcinating the above titanium-slag. Key words: ilmenite; mechanical activation; hydrochloric acid; leaching 随着天然金红石资源的日渐枯竭,储量丰富的钛铁矿已成为钛工业的主要原料.然而,钛铁矿中钛的品......
