Improved grinding of titaniferous ores to enhance recovery of titanium dioxide

Significant enhancement of titanium dioxide recovery from a titaniferous ore is achieved by improving the efficiency of the comminution of the ore with the use of polyols of the formula: R - C &lparstr& R min OH)3 wherein R is alkyl (C1-C4), or hydroxyalkyl (C1-C4) containing up to 3 hydroxy...
