Since all zinc concentrates contain iron, and the iron minerals are leached during pressure leaching, the behavior of iron is controlled by the acid content of the pressure-leach solution. The pressure leach of zinc concentrate is normally designated as a low-acid leach or a high-acid leach.

As described in the lead-zinc process description, in some instances enhanced iron sulphide depression can be improved by aeration prior to the differential Cu-Pb flotation step. Most often the copper minerals are floated after galena depression.

Lead flotation experiments were performed under three conditions aiming at verifying the influence of the dispersing agent, of the pH, and of sodium carbonate. The zinc flotation tests were carried out at pH 10.5, modulated with lime.

In the reverse flotation of iron ores, froth washing was found effective in reducing the loss of FINE iron oxide particles to froth. It was reported that the cost of installing a column flotation circuit is approximately 25% - 40% less than an equivalent flotation circuit of mechanical flotation cells[60].

Froth flotation is used to separate zinc from other minerals after grinding the ore. The final concentration of zinc is about 50% using this method, the remainder being sulfur and iron. Froth Flotation. By a process known as froth flotation, zinc can be produced. Froth flotation is also used in the reduction of copper and lead ores.

The relative galena and sphalerite contents do not change the surface chemistry and tend only to have an impact in cases where the galena content is higher than the sphalerite content, e.g. at Cannington where if the lead feed grade relative to zinc is too high, then too much of the faster floating zinc with lower iron content is recovered to the lead …

The development of froth flotation has improved the recovery of valuable minerals, such as copper- and lead-bearing minerals. Along with mechanized mining, it has allowed the economic recovery of valuable metals from much lower grade ore than previously.

Advantages of froth flotation: first of all, almost all minerals can be separated by this process. Then, the surface properties can be controlled and altered by the flotation reagent. Finally, this technique is highly appropriate for the separation of sulfide minerals.

Froth flotation is again employed to produce marketable concentrates of both. The process is identical in principle to the flotation of other minerals. The figure on the right is a simplified version of a Pb/Zn flotation circuit. The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated.

Frothers, as defined by flotation operators, are compounds used specifically for creating a flotation froth. However, most collectors used in iron ore processing produce adequate froths. The general types of these frothing collectors include long-chain carboxylates, sulfonates or sulfates, and amines as listed in Table 9.1.
