Jul 23 2014 · Froth Flotation and Gold Extraction July 23 2014 0639 Air bubbles are pumped into the flotation cell and the water is agitated Because of the surfactant the gold is repelled by the water into the air bubbles which rise to the top – creating a bubbly gold foam The froth is removed from the top of the cell creating concentrated gold

This corresponds to the underflow and in the case of direct flotation to the tailings Figure 2 illustrates the flotation process within a column Figure 2 Flotation process within a column Typically columns are suitable for ores with a particle size bellow 150 µm Larger particles tend to

2 The particle must be suspended in the pulp phase of the cell 3 The particle must collide with a rising bubble 4 The particle must adhere to the bubble 5 The particle must not detach from the bubble during passage through the pulp phase 6 The particle must not detach from the bubble as the bubble leaves the pulp phase and enters the froth phase 7

The behaviour of free gold particles in a simulated flash flotation environment comprised of primarily of ‘free gold’ because the BCC units are not designed to recover bulk sulphide material The ‘GRG test’ Laplante and Dunne 2002 and model generates results

Flotation circuits are often operated at a pH range of 75 to 115 The exact range at any given plant is optimized for the ore at that site Lime is often used to raise the pH of the pulp and also reduce the flotation of iron pyrite Particle Size The particle size to which the ore is

For example if 20 of the water entering a flotation cell is carried into the froth then up to 20 of the fine particles entering the cell will be entrained The entrainment of coarser particles will be less than 20 due to their greater ability to drain from the froth

flotation which invariably leads to higher gold recovery since the majority of the unliberated gold particles were associated with pyrite as fine inclusions 13µm 1 7

Flash flotation was developed several decades ago with the first commercial installation of this technology being at Hammaslahti concentrator in Finland in 1982 Kallioinen and Niitti 1985 This was a relatively modest sized SK80 cell producing final grade copper concentrate Since that time the

Apr 06 2010 · “The supernatant control” A gold nanorod solution is exposed to cells and in this cartoon kills 70 of the cells at a certain dose An identical gold nanorod solution is centrifuged and the colorless supernatant exposed to cells The

as pyrites In a typical pyrytic gold ore the gold is encapsulated within an iron sulfide crystal structure Highly oxidized ores generally do not respond well to flotation 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

recoveries of the order of 84 and 73 of the gold content Fig 1 shows seven mills downloading the pulp to a conditioner in which collectors frothers and lime are added The numbers of cells are1301 rougher 01cleaner and11 scavenger The firstscavenger circuit is composed of 2 cells the second 5 cells and 4 in the third circuit
