Plant Optimisation at Deno Gold, Armenia

Plant Optimisation at Deno Gold, Armenia

We were commissioned to undertake a series of on-site optimisation studies for the copper-zinc-gold mine in Armenia. The Client was interested in finding means to increase gold recovery in their flotation plant.

Initially, work was undertaken in our Laboratories in Cornwall.  Flotation tests identified a particular flotation collector which increased gold recoveries by 3%.  We were then commissioned to undertake further testwork in the company‚Äôs on-site laboratory and this was followed by plant trials which confirmed the potential recovery increase.     

Finally, we were also commissioned to investigate methods of treating old mine dump material through the Plant.  This involved further laboratory and process plant trials which resulted in defining the process conditions and treatment methodologies.
