Enhanced methods for nickel recovery from low-grade ores and bleed streams

Here, chemical separation is used: chemicals are added to make some minerals repel water, allowing the minerals to float to the surface, this froth is then removed - designed to remove copper concentrate. The second stage of froth flotation produces a nickel concentrate of 10-20% Ni, along with other by-products and gangue.

12.3 Primary Copper Smelting - US EPA

Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions.

Copper Ore Processing Methods - Metallurgist & Mineral Processing Engineer

Flotation, when first introduced between 1913 and 1916, was used primarily to reduce losses of copper in the fine tailings of gravity plants. From an accessory to gravity methods, flotation very rapidly became a major process and finally, from 1923 to 1927, all but eliminated the gravity method in the treatment of low-grade sulfide copper ores.
