Abstract
A process of flotation of partially or fully liberated metal-bearing or industrial minerals, hydrocarbon matter, oil or bitumen from an ore includes combining an indifferent salt to a flotation system to increase efficiency of the flotation process as well as the subsequent flotation concentrate and tailings solid-liquid separation.
Claims20
A process of separating materials by flotation, the process comprising:
- forming a feed slurry, which includes solid particles in ion managed water, in a flotation operation, wherein the ion managed water has a concentration of dissolved indifferent monovalent ions of 0.3 wt % to 5 wt % and a concentration of dissolved multivalent ions of no more than 0.3 wt %, and
- recovering the materials including at least one selected from oil, bitumen, hydrocarbon, coal, tar, a halide, a fluoride, a chloride, a carbonate, a silicate, and an oxide.
A process of separating materials by flotation, the process comprising:
- treating a source of water to have a first concentration of dissolved indifferent monovalent ions and a second concentration of dissolved multivalent ions in the source water to form an ion managed water,
- combining the ion managed water with crushed ore to form a feed slurry, which includes solid particles in the ion managed water, in a flotation operation, and
- recovering the materials including at least one selected from oil, bitumen, hydrocarbon, coal, tar, a halide, a fluoride, a chloride, a carbonate, a silicate, and an oxide,
- wherein the first concentration is sufficiently high and the second concentration is sufficiently low to improve the flotation operation and improve a liquid-solid separation operation.

A process of separating materials by flotation, the process comprising:
- treating water reclaimed from a tailings storage facility to form ion managed water having a concentration of dissolved indifferent monovalent ions of 0.3 wt % to 5 wt % and a concentration of dissolved multivalent ions of no more than 0.3 wt %, the treating of the water includes adding indifferent monovalent salts to the water to increase a concentration of indifferent monovalent ions in the water, wherein the indifferent monovalent salts are added in dry form or dissolved in an aqueous medium,
- forming a feed slurry, which includes solid particles in the ion managed water, in a flotation operation, and
- recovering the materials including a fluoride.
