Decomposition of ilmenite by ammonium hydroxide

摘要：

　　A new process was provided for decomposition of ilmenite by ammonium hydroxide under hydrothermal process.The significant effects of reaction temperature, NH4 OH concentration, NH-4OH-to-ilmenite mass ratios on titanium extraction were studied.The temperature showed significant influence on titanium extraction.The experimental data of the extraction rates under the relevant operating variables were well interpreted with the shrinking core model under chemically controlled process.
