Abstract

Flotation of coarse particles of ore, particularly sylvinite ore, by passing concentrated conditioned pulp (about 60-70 percent solids) to top of cell just below overflow level, and passing a mixture of air and liquid into bottom of cell to float coarse particles, there being minimal turbulence but sufficient air bubbles for efficient flotation. Suitable apparatus is also provided comprising the flotation of coarse particles, said apparatus comprising a vertical tank, said tank being provided with discharge means, means for the overflow of floated particles suspended in carrier fluid, pulp feeding means at the upper portion of said tank terminating at a level below said means for the overflow, and at the lower portion of said tank means, fixed means for introducing a carrier fluid, and adjacent to said fixed means, fixed dispersing means for the introduction of a supplementary quantity of carrier fluid, said vertical tank further comprising velocity regulating means disposed in said tank for increasing the velocity of said carrier fluid after it is introduced into said tank, and then decreasing the velocity of said carrier fluid prior to reaching said overflow means.
