Abstract: A method of removing metal particles from a contaminated metalworking fluid comprising emulsion droplets and metal particles includes pressurizing a first clean metalworking fluid with gas to provide an aerated metalworking fluid; releasing the pressure of the aerated metalworking fluid to form a plurality of bubbles; applying a shear force to the contaminated metalworking fluid to separate the emulsion droplets from the metal particles; flowing the contaminated metalworking fluid with the aerated metalworking fluid in a laminar flow to form a combined fluid, wherein the flowing occurs during the formation of the plurality of bubbles and while the emulsion droplets are separated from the metal particles, and wherein the laminar flow lasts for a time sufficient for the plurality of bubbles to attach to the metal particles; releasing the combined fluid into a flotation tank; and removing the metal particles to form a second clean metalworking fluid.

Abstract: A method of controlling operation of a froth flotation cell comprises introducing gas into a liquid in the cell, thereby to create a froth on the surface of the liquid, which froth overflows and leaves the cell at an overflow point, wherein the froth has a froth height from the level of the overflow point to the upper surface of the froth, measuring values of the froth height for two values of gas flow rate into the cell, measuring values the velocity at which the froth overflows at the overflow point for two values of gas flow rate into the cell, calculating a gas flow rate into the cell that optimises gas recovery, by treating the measured values of froth height and measured values of froth velocity independently, and setting the gas flow rate into the cell to be the calculated flow rate into the cell that optimises gas recovery.

Abstract: Copper values are efficiently recovered from a copper ore, including secondary sulfides, by first crushing the ore to a particle size P-80 of about 1 to 2 inches, then grinding the so crushed ore to a particle size P-80 of between Tyler 4 mesh and 20 mesh, and then classifying the ground ore into a fines fraction of less than 65 mesh and one or more coarse fractions of more than 65 mesh. The fines are then leached or subjected to flotation to form a concentrate which is leached to form a pregnant leach solution. In parallel, the coarse fraction or fractions are leached also to form a pregnant leach solution. The leaching operations are carried out with ferric sulfate lixiviant at atmospheric pressure and elevated temperature. During leaching ferric sulfate is reduced to ferrous sulfate. The pregnant leach solutions are then subjected to solvent extraction to recover the copper values and subsequently to electrowinning to produce copper metal. During the solvent extraction operation, free sulfuric acid is produced and is then used together with oxygen to oxidize the ferrous sulfate produced during the leaching steps back to ferric sulfate with is then re-used in the leaching of the fines and coarse fractions.
