The Zinkgruvan mine in Sweden uses bulk flotation of galena and sphalerite followed by depression of the sphalerite to produce separate galena and sphalerite concentrates; however, it is still a variation on the traditional approach in that after the bulk float, it is still sphalerite that is depressed first...
