What is refractory ore?

§ Mineralised rock resistant to

recovery by standard cyanidation adsorption methods

§ Generally contains sulphide

minerals, which encapsulate gold particles, making it difficult for the leach solution to reach the contained gold

§ Oxidation of sulphide minerals

is necessary to recover the gold

§ May also contain organic

carbon that impedes recovery Takes several million years to free up

Natural Oxidation Process

Artificial Oxidation

§ Mineralised rock resistant to

recovery by standard cyanidation + carbon adsorption methods

§ Generally contains sulphide

minerals, which encapsulate gold particles, making it difficult for the leach solution to reach the contained gold

§ Oxidation of sulphide minerals

§ May also contain organic

carbon that impedes recovery POX takes 45 minutes Processing options for refractory ore

The Blagoveschensk pilot POX plant

§ First and only one of its kind in Russia, built 2011

  • Allows for extensive testing and optimisation of a full range of operational

parameters (temperature, pressure, flow rate)

  • Used to train personnel

§ Replicates industrial scale plant including automation and control systems

  • Exactly replicates processes and controls to be used at the future plant
  • Accurate prediction of recoveries, reagent consumption and operating costs
  • Complete understanding of the process before operations commence

§ Scaled process replication = de-risked technology

  • Brings confidence to the POX plant design – laboratory test work replicate

conditions in industrial production The only pilot scale autoclave in Russia Unique pilot test plant = in depth simulation, project de-risked

Why is refractory ore the future of gold mining?

§ The world is running out of easily

treatable ore

  • Exploration is failing to balance out

depletion of non-refractory ore

  • Approximately ¾ of Russia’s reserves

are refractory or partly refractory in nature, incl. Russia’s largest gold deposit, Sukhoi Log

§ A gradual shift towards refractory ore

processing

  • Barrick Gold, Newmont Mining,

Newcrest Mining, Agnico Eagles

§ Refractory ore processing technologies

have been successfully employed for decades around the world

  • First plant for base metals launched

1952, first gold POX plant launched 1985 (McLaughlin, USA)

Kittila processing complex Autoclaves at Pueblo Viejo
