Froth Flotation Process

Froth flotation is used to recover copper sulfide minerals including chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4), and chalcocite (Cu2S). The ore is crushed in the copper froth flotation process in order to separate the copper minerals from the gangue minerals.

Flotation Machine

The flotation process is the most efficient, most widely used, and most complex of all mineral concentration methods in use by the mining industry. Froth flotation is the principal means of processing copper, molybdenum, nickel, lead, zinc, phosphate, and potash ores.

1 Froth Flotation – Fundamental Principles

After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate: (a) Ratio of concentration (b) % Metal Recovery (c) % Metal Loss (d) % Weight Recovery, or % Yield (e) Enrichment Ratio Table 1: Grade/recovery performance of a hypothetical copper ore flotation process.

Lab #5 – Froth Flotation

all sulfide minerals are treated by froth flotation, as well as many oxide minerals and industrial minerals. In this process, mineral particles that have an affinity for air, known as hydrophobic particles, selectively attach to air bubbles and are recovered in the froth at the surface of the flotation machine.
