Introduction. A mineral of ilmenite type is a common raw material to produce titanium dioxide and titanium metal. The ilmenite concentrate from Panzhihua, which is …
Mechanical activation significantly accelerated the dissolution of Panzhihua ilmenite in a 50% sulfuric acid solution. As high as 82.1% of conversion was obtained by leaching the 60 min milled ilmenite at 100 °C for 2 h. The leaching rate was apparently linked with the lattice strain of ilmenite crystal. The dissolution reaction responded more ...
