flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants.

This work aimed to determine the bioconcentration and bioaccumulation of copper in eucalyptus species and how they affect the physiology of plants. The experimental design was completely randomized in a factorial arrangement (4 × 6), with four species of eucalyptus ( Eucalyptus grandis W. Hill ex. Maiden, Corymbia citriodora (Hook.)

Milling. Once the copper ore has been mined, it must be milled to separate the copper from the rest of the rock. This is done via crushing and grinding. Concentrating. The next step in copper production is concentrating. This process involves adding chemicals to the milled ore to separate the copper from the rest of the metals present. Smelting

The underflow is sent to a secondary ball mill and trommel screen, for additional grinding and classification. Using froth flotation, the copper minerals separate from the gangue and rise to the froth layer of the flotation cell. In turn, the copperrich bubbles are removed or transferred to the next stage of flotation for further processing.

The processing plant is a conventional porphyry copper concentrator that produces a primary copper sulphide concentrate and a byproduct molybdenum concentrate. The plant flowsheet is typical of its era with primary through tertiary crushing, ball milling and conventional flotation. The mill has undergone several optimizations during its life.
