The Filblast Cyanidation Process - ausimm

The Filblast Cyanidation Process incorporates the advantages of intense high shear mixing, high dissolved oxygen concentration and high pressure to achieve extremely rapid gold dissolution rates. This is made possible by the unique design of the Filblast gas shear reactor. The reactor is a rugged and compact in-line device. The outer casing is protected by a polyurethane coating and the ...

2000-1-1  The Filblast cyanidation process applies all of these factors in a simple, robust device that increases the cyanidation kinetics and the ultimate gold extraction. It is these characteristics of the process that Atomaer has addressed with outstanding results. In simple terms, the Filblast acts like a carburettor, the more dissolved oxygen, the ...

2021-10-23  Filblast was a fairly early innovation to improve the air flow so that one did not need pure oxygen or peroxide and at the time was cheaper than both. The Filblast is a high shear, pressure reactor. In the design, the reactor/feed pump relationship has been established to give a specific shear rate within the agitated cyanidation system.

Using life cycle assessment to evaluate some

Abstract The environmental profile of gold production with regards to embodied energy, greenhouse gas emissions, embodied water and solid waste burden has been assessed using life cycle assessment methodology. Both refractory and non-refractory ores were considered, with cyanidation extraction followed by carbon in pulp (CIP) recovery assumed for non-refractory ore processing.

Strategies for the optimisation of gold processing plants

Effect of pH on Au Recovery in the Presence of 0.25% Stibnite (After Hedley Tabachnick 1968) Extrapolating the above trend back to the ordinate axis we note that 100% recovery is once again achieved at pH 8.9 but with the reservation that gold recovery will reduce somewhat, and cyanide consumption increase, as the free CN- ion is replaced by dissolved HCN at the lower pH.
