Advanced Technologies of Gold Ore Processing Systems

Breakthrough Technologies Successfully unlocking the micron gold and precious metals, discovered trapped within ore.

High Yield – Low Cost Mine Process

Picchu Rio Gold has partnered with 3 US companies for years in efforts to unlock the vast wealth of Gold, Platinum and Palladium contained within the alluvial and colloquium deposits of the river of running gold of Inca history. Over the past two years major breakthroughs were attained via application of proprietary processing technologies, invented by Avimetal Inc., by Coronet Metals US Inc. and Minerals Processing Corporation in partnership with ESM and PRG of Peru.

  • Incorporation of highly effective and environmentally safe leach regents
  • S. Korea 3rd party processing contracts via Avimetal’s engineered systems and proprietary equipment
  • Onshore Processing Contracts by ESM’s Avimetal equipped plant.

This small class mining company, 99% owned by its American controlled parent company Picchu Rio Gold Mining Company S.A., is located in the Cusco Department, La Convencion Province and Echarate District of east central Peru. Ready to upscale!


Ultra Fine Micron Mill is a patented, innovative, and commercialized method for particle size reduction to reduce, within seconds, solids that are capable of fracturing into a particle-sized powder. It replaces a conventional ball mill, impact mill, hammer mill, tower mill, etc. Ultra fine Micron milling has created the potential to revolutionize the mineral processing industry due to the benefits attained through being able to economically mill finer and to enhance particle liberation for improved precious metals recovery. A ultra-fine icron Mill by means of tornado/vortex airstream. The Micron Mill is done by mechanical impact of rotating impeller as well as intensive vortex airstreams and high frequency of air pressure oscillation generated at the backside of rotating rotor and the groove slopes.  Material is taken into the mill being carried by airstream. The airstream containing material is given spiral motion in the inlet spiral chamber and transmitted evenly into the milling chamber.


An electrostatic separator is a device for separating particles by mass in a low energy charged beam. It works on the principle of corona discharge, where two plates are placed close together and high voltage is applied. This high voltage is used to separate the ionized particles. Electrostatic separation is a process that uses electrostatic charges to separate crushed particles of material. This process can help remove valuable material from ore. Generally, electrostatic charges are used to attract or repel differently charged material.

Quadrant Roller Electrical Sorter is one of the major equipment in electricity mineral separation. The disadvantage of the roller type is a limit for separating micron size as most precious metal forms in tiny micron size and low capacity of separation (1 ton per hour).

We have developed a low costs electrostatic separators which are combination of roller type and belt type superiors. Our belts are vertically positioned and 8 pairs of small belts are in the system. Advantage of this system compared to competitors are compact size, low sales price ($50,000),  ability of separating micron size, large production capacity and using low power.
