About Us

Just Refiners (USA) Inc was incorporated in 1993. Just Refiners is situated in Sparks, Nevada. Just Refiners is currently expanding into processing spent carbon in house. Phase 1 of this expansion program will create 10 new jobs.

The main core business of Just Refiners is to provide a service to the mining industry by receiving, preparing, sampling and processing their by-product materials. The mine by-products consist of:

  • Spent Carbon
  • Borax Slag
  • Mill Concentrate
  • Mine Concentrate
  • Matte
  • Dore Bullion

At all times, the weigh-in and the sampling for evaluation of the by-product materials received at JRI, are witnessed by the mine or a representative appointed by the mine. A number of representative samples are taken from the homogenized materials and submitted to external laboratories for precious metal determination. The customer is provided with a representative sample.

Meticulous care is taken of the necessary preparation and treatment of the by-product materials to enable representative sampling from homogenized by-product materials. In the event, where the gold and silver analysis is outside the permitted splitting limit, the reserve sample is submitted to an Umpire laboratory like Bureau Veritas, AH Knights, Chris Christopherson Inc, ALS Global or Alex Stewart Assayers, Inc for comparative determination. The appointment of the Umpire laboratory is agreed to by both parties.

Just Refiners is able to provide the mines with a hedging facility to price the gold and silver contained in their by-product materials. In addition JRI pays the mines promptly based on the precious metal content less the agreed treatment charges.
