More ores are treated using froth flotation cells than by any other single machines or process. Non-metallics as well as metallics now being commercially …
In fresh water, the oxidation of pyrite at alkaline pH inhibits the copper activation on pyrite surfaces and the depression of pyrite in copper ore flotation is normally not a problem (Li et al., 2012). However, saline water facilitates pyrite activation by copper ions and therefore increases pyrite recovery in copper flotation (Mu and Peng ...
Unfortunately, the conventional flotation cell achieves high recovery only in limited size ranges. For example, a sulfide ore might float very well at 90 to 120 microns, but not at 50 or 150 microns.
Figure 1 is a generalized diagram of a conventional copper flotation plant from the point where ore first enters the circuit to the production of concentrate and tailings. To prepare ore for the flotation process, run-of-mine ore, which may contain from about 2 to 5 percent water, by weight, when mined, is
The test is a means of determining the flotation characteristics of an ore. It is conducted in a laboratory scale cell usually with a volume of two point five litres. The intention is to generate relationships of cumulative recovery, mass pull and grade versus time and use these to evaluate the floatability of metal, mineral and gang.

Due to microbubble stability problems in agitated flotation cells, microbubble flotation is primarily carried out in column-type flotation cells . Laboratory experiments were performed using this technique to recover copper, zinc, and lead from a complex sulfide ore of <5 µm size [60,66].
All the flotation test-work was done using the Denver laboratory machine with a 1.5l stainless steel flotation cell. The required mass of nickel-copper sulphide ore material ground to 70% passing 75 µm was weighed and placed in the flotation cell. This was followed by the addition of distilled water to about
In this study, the robust Taguchi experimental design method was used to determine the optimum conditions for the flotation of nickel, copper and cobalt from a nickel-copper sulphide ore.
The flotation of iron ore started with the direct flotation of iron oxides using anionic collectors, but was latter largely replaced by reverse cationic flotation which has become the most widely used flotation route in the iron ore industry.
