摘要： The invention relates to processes for the extraction of products from titanium-bearing minerals. In particular embodiments the invention relates to methods of recycling sulphuric acid used in a titanium dioxide extraction process. The invention also relates to methods for minimising chromophore contamination in calcined titanium dioxide. The process may also comprise steps for removing contaminants from recycled acid or desirable products.
