Tungsten resources are abundant and varied in China. At present, wolframite is decomposed by alkali and scheelite is decomposed by hydrochloric acid or boiled by soda. For quite a long time, experts at home and abroad generally believed that it was impossible to decompose scheelite by alkali (NaOH) in industry. Until Professor Li Honggui of Central South University put forward the hot-ball milling alkali decomposition process, which broke the convention.
