1. Barite-fluorite Ore Flotation Process Barite-type fluorite ores primarily contain barite as a gangue mineral (usually 10-40%) and are often associated with minor sulfide minerals (pyrite, galena, sphalerite), with some deposits containing a higher quartz content. Given the similar floatability of barite and fluorite, a flotation process involving the preferential bulk flotation of fluorite and […]
