- Froth Flotation Copper Ore Processing Plant
Froth flotation. Froth flotation is one of the most commonly used concentration steps in mineral processing and the Cu–Co industry is no exception. After the valuable minerals have been liberated from the waste rock, froth flotation is used to selectively concentrate and separate the valuable ore from the gangue material.

Froth Flotation: Froth flotation is a common method used to separate copper minerals from the gangue (waste rock) and other minerals in the ore. In this process, the crushed and ground ore is mixed with water and chemicals, including collectors, frothers, and modifiers, which selectively attach to the copper minerals and …

Flotation performance is most commonly represented using grade-recovery curves, with a shift upwards and to the right indicating an improvement in performance. The problem with using grade recovery curves, especially on plant data, is that position and shape of the curve is strongly influenced by both the feed rate and grade to the circuit.

Fig. 2 shows the P 80 of different mineral species in an ore for a major copper operation. These values vary significantly, with the P 80 of total solids, sulfide minerals, iron minerals, copper minerals and molybdenum are ∼ 200, 105, 125, 94 and 85, respectively. Flotation optimization of complex ores often requires a better …
