The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out.

Figure 1: The flotation system includes many interrelated components, and changes in one area will produce compensating effects in other areas (Klimpel, 1995) Froth flotation is a good example of an engineering "system", in that the various important parameters are highly inter-related, as shown in Figure 1.

Flotation and leaching processes were added to the mills to boost copper recovery as ore grades declined. (US Bureau of Mines) The Quincy Dredge sits abandoned along the shore of Torch Lake. As ore grades declined in the mines, the companies dredged and reprocessed the tailings from earlier mills.

Flotation Flotation is an innovative processing method for separating valuable minerals locked in waste rock. It abandons basic principles of ore treatment by gravity methods previously followed by early metallurgists. At the end of the nineteenth century, the world had almost exhausted its supply of high-grade ore.

Froth flotation is a process for selectively separating of hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Gold flotation. Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfide-containing gold ore with high floatability. In addition, the flotation process is also used for polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-copper-lead-zinc-sulfur ore.
