This method of concentration is known as (a) metallurgy (b) leaching (c) froth floatation process (d) gravity separation. Answer. Answer: (d) gravity separation

Froth Flotation - an overview ScienceDirect Topics

The froth flotation technique was originally developed in about 1910 to raise the copper concentrations of the strip-mined ores of Bingham Canyon, near Salt Lake City [9], and was further perfected for the differential separation of lead, zinc, and iron sulfides at Trail, B.C., at about the same time [10]. Flotation technologies are now widely ...
