  • Titanium Ore Processing and Beneficiation

    High density conditioning in a slightly acid circuit, pH 6.0 to 6.5, with H2SO4, sodium fluoride, and oleic acid actuates the titanium minerals for rapid flotation. This computation effectively rejects the gangue minerals and any apatite. Flotation is in "Sub-A" Flotation Machines with 30-35% solids with fuel oil and a frother added as .

    Computerized image analysis can be useful in estimating phosphate grain or gangue mineral sizes. While the phosphate grains and gangue mineral grains may occur in some rocks as distinct particles, some rocks contain significant amounts of gangue minerals occluded within phosphate particles. Cement-particle relationships are also important.
