Notes:
Today, the phosphate rock processed in the world represents around some 20 billiondollars per year. Some exploitable deposits are characterizing by low grade phosphate rocks,composed of the apatite group in association with a wide assortment of accessory minerals. Usuallya combination of beneficiation techniques is used to process a phosphate rock since run of mine,and then a flotation is applied to recovery apatite. This work proposes an evaluation of particle sizefor apatite recovery by column flotation in bench-scale. The variables collector dosage anddepressant dosage were investigated experimentally applying a factorial design. According to theexperimental results, the particle size range between 37&m and 105&m is an optimum size used toobtain simultaneously a product with the industry demand grade (at least 33%) and phosphorusrecovery, upper than 60%
