Copper Flotation Mineral Processing & Metallurgy

16/05/2016 The flotation of native copper ores is nearly always preceded by gravity concentration in jigs and tables not only because the combined process is more economical as regards costs, but also because the copper often occurs as large grains which flatten out during grinding and cannot be broken to a size small enough for flotation

Copper Sulfide Flotation Mineral Processing &

13/04/2016 Porphyry ores, with copper occurring in the form of Chalcocite and Chalcopyrite are normally low in grade and the copper minerals must be concentrated before smelting. In this flowsheet using “Sub-A” Cells the emphasis is on maximum economic recovery—high concentrating efficiency together with a premium smelter feed with a low alumina and magnesia content in the flotation

Schematic view of flotation cell. Reagents cause Cu–Fe sulfide and Cu sulfide minerals in the ore to attach to rising air bubbles, which are then collected in a short-lived froth. This froth is de-watered to become concentrate. The un-floated waste passes through several cells before being discarded as a final tailing. Many types and sizes (up to 300 m 3) of cell are used.

Froth flotation

Before froth flotation can work, the ore to be treated is reduced to fine particles by comminutionso that the various minerals exist as physically separate grains. This process is known as liberation. The particle sizes are typically less than 0.1 mm (100 µm), but sometimes sizes smaller than 7–10 µm are required. There is a tendency for the liberation size of the minerals to decrease over time as the ore bodies with coarse mineral grains that can be separated at larger sizes are depleted

Mineral Flotation International Mining

01/11/2011 “Recovery of copper oxide minerals can be achieved with flotation by sulphidising the ore. In essence, this creates a thin layer of copper sulphide (chalcocite) on the oxide grains which can then be activated and collected in the froth. When employed, this occurs after the sulphide flotation stage, however, this is not commonly used as other beneficiation

Froth Flotation Circuit Design And Basic Testwork

Most flotation circuits include an initial stage of rougher flotation, followed by a scavenger stage of flotation. The objective of passing through the rougher and scavenger flotation circuits is to maximise recovery of the desired minerals into relatively low grade concentrates that may typically contain 5-15 weight percent of the ore feed, (directly related to ore grade). Depending on the

Parametric Optimization in Rougher Flotation Performance

The dominant challenge of current copper beneficiation plants is the low recoverability of oxide copper-bearing minerals associated with sulfide type ones. Furthermore, applying commonly used conventional methodologies does not allow the interactional effects of critical parameters in the flotation processes to be investigated, which is mostly overlooked in the literature.
