ANIONIC ROUGHER-CLEANER FLOTATION

Direct flotation using anionic reagents was practiced on high-grade flotation feeds in some U.S. plants, and is still being used in a Mexican plant. Some research efforts have also been directed at developing an anionic flotation process for phosphate, but the interest faded due to the stringent requirement for Insol (at 4-5%) content in the

According to the mineralogy of a low-grade Ni-Cu-PGM sulfide ore, a leaching-flotation process was introduced to process the ore. The leaching tests were focused on temperature, acid concentration, and grinding fineness under normal pressure. Results show that most of Mg and Fe can be effectively leached by 25% H2SO4 with a small amount of copper and nickel loss in leaching solution.
