Advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized.
The feed to primary crushing is generally run of mine ore, which is reduced from large pieces (2 to 4 feet in dimension) to smaller pieces (8 to 10 inches in dimension). Primary crushing systems are typically located near or in the pit at surface mines or below the surface in underground mines.
However, this process is based upon density alone and should not be confused with the process of froth flotation. Thus, the process of froth flotation is not solely dependent upon the density of the material; it is also dependent upon its hydrophobic nature.
Jan 24, 20140183;32;Just because a web page mentions it, that does not mean flotation of free gold is a commercially viable process There are loads of gold mines all across the world. Many use flotation to recover sulfides. I doubt there is a single one that uses floatation to recover free gold as their normal ore processing method.
Gold separation process with concentration / separation by gravity methods utilizing differences in density of the density of gold with other minerals in rocks. That in general the density of gold (19.3 ton/m3) and the density of other minerals in rocks generally range from 2.8 ton/m3).

effect. Softer ore would require mill speed decrease to maintain a satisfactory ore bed and grinding conditions, while protecting the mill liners from direct impact. Conversely for hard ore, mill speed is increased to input more energy to the process and improve
A gold recovery method, called the coal gold agglomeration (CGA) process, whereby hydrophobic gold particles are recovered from ore slurries into coal oil agglomerates, and the subsequent burning of these agglomerates to recover the gold, was developed some years ago.
Concentration is the process of extracting the economic product from the crushed and ground ore, the waste from this process is the tailings. Froth flotation (figure 2) is the most widely used concentration method and is normally the first step in the mineral processing sequence where chemical reagents are introduced (Vick 1990).
The response of many minerals to the flotation process is often dramatically affected by pH. Flotation circuits are often operated at a pH range of 7.5 to 11.5. The exact range at any given plant is optimized for the ore at that site.
In the next step, flotation process was conducted to t est the effect of pulp density. The studies were carried out at pH 11.0 a nd the weight of sample varied at 200 g, 250 g, 300 g and 350 g.

original ore showed that the sample contained 4.93 % Cu, 0.007 % Co, 0.92 % Zn, 11.41 % Fe, 10.72, % S, 4.72 g/t Au and 12.80 g/t Ag. It was determined that gold and silver could not be reached with satisfactory yields by flotation of original ore at the defined size. Thus, original ore was
Froth Flotation / Separation flotation Froth flotation is a separation process ore from mineral impurities by way of float ore to the surface through binding to the froth. Gravity Separation / gravity separation Concentration / separation by gravity methods utilizing

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
Dewatering is an important process in mineral processing. The purpose of dewatering is to remove water absorbed by the particles which increases the pulp density. This is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue.
Froth flotation. Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. 3 Principle of operation However, because the Bessel process was used on graphite not gold, silver, copper, lead, zinc, etc, their .

Flotation can be used on oxide ores, typically they are sulphidised first to allow the flotation process to work. Without the benefit of understanding the geology, proposed rate of production, etc, in an ideal situation I'd consider gravity concentration as the first process.
