Ore Concentration by Froth Flotation Remember that only 0.67% of the ore is copper. The copper minerals and waste rock are separated at the mill using froth flotation.


Problem: A copper ore initially contains 2.09% Cu. After carrying out a froth flotation separation, the products are as shown in Table 1. Using this data, calculate: (a) Ratio of concentration (b) % Metal Recovery (c) % Metal Loss (d) % Weight Recovery, or % Yield (e) Enrichment Ratio


Oxide copper ores in subdivided form may be concentrated in a flotation separation process by slurrying said ores in an aqueous solution of a flotation reagent followed by generating gas bubbles in the slurry to float the oxide copper and recovering the concentrated oxide copper from the surface of the slurry, wherein the flotation reagent is a quaternary hydrocarbyl ammonium …


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.


For example, when copper is in the form of carbonate (malachite, blue copper ore), the flotability is relatively good, while the flotability of silicate (silica malachite) is poor, free copper oxide is easy to float, and copper oxide can not be recovered by a single flotation method.


The Flotation Process The Flotation Process Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless.


Answer (1 of 2): Flotation is a beneficiation method based on the hydrophobicity difference of the mineral surface. While the copper mineral is usually in the form of sulfuration exiting in the mineral. The natural floatability is good, so flotation is …


Copper sulfide can be divided into single copper ore, copper sulfur ore, copper-molybdenum deposit, copper nickel, carrollite and so on. Basically, only flotation can be considered in its separation. Almost all copper sulphide ores contain iron-bearing sulfides, so in a sense, the flotation of copper sulfide is essentially the separation of ...


The ore is a sulfide copper ore containing heads of approximately: copper 0.45, iron 3.4, molybdenum 0.006, and zinc 0.06 per ore sample. Prior flotation of this ore has employed, in the floation cell, the addition of pine oil as required to optimize froth, ordinarily resulting in a total pine oil concentration of about 0.24 lb./ton.


This flotation step is conducted at alkaline pH. In the case where galena is floated and the copper minerals are depressed, copper depression can be achieved by using sodium sulphide, hydrosulfite, lime, cyanide, zinc-cyanide and/or ferricyanide complexes. Selection of flotation reagents and frothers is an important, even critical, consideration.

Copper Ore Processing Methods

Oxidized ores in which malachite, azurite, and chrysocolla are the predominant copper minerals that do not respond either to gravity or simple flotation methods. Sulfide-filming of the carbonates followed by flotation of the filmed minerals, or direct leaching followed by precipitation of the copper from the solution may be employed for such ores.
