WO1995008004A1 - Ilmenite processing using cold milling ...

High energy ball milling of particulate ilmenite (or other titaniferous ore) at room temperature, for periods of up to 300 hours, in the presence of a suitable additive, produces a nanostructural powder from which at least a major proportion of the iron in the titaniferous ore can be leached. The additive may be a reducing agent (for example, amorphous boron), a long chained hydrocarbon (for ...
