A multi-pronged approach involving dissolution, adsorption, precipitation and flotation studies was used to determine the role of surface area and porosity on the floatability of apatites of different type, sedimentary or endogenic, and origin. When

During phosphoric acid manufacture, phosphate rock is reacted with sulfuric acid and the by-product, gypsum, is separated using vacuum, belt or pan filters. Filtration efficiency is known to depend on the size distribution and shape of the gypsum cry
