Froth flotation is a key process in the extraction of copper, particularly from sulfide ores. The ore is first crushed and ground into a fine powder, then mixed with water to form a slurry. Chemical reagents called collectors are added to the slurry to make the copper sulfide particles hydrophobic (water-repellent).
