It has received a 30kg sample of mineralised material from the customer and a payment for this work. The goal of this work is to demonstrate that its proprietary CLEVR process can extract gold at a rate of 95% or better.
Brian Howlett, president and CEO of DST, commented: "Management of DST is very excited to be developing our CLEVR process technology into China at this time. China controls a key portion of the gold and base metals processing capacity in the world and will be a key market going forward for our technologies."
DST completed analysis of the samples in December 2018 and has been able to increase recovery of the gold from the customer's concentrate from 71% using cyanide to over 90% at a lab scale using its technology.
The company has also submitted a 5kg sample of glass from the GlassLock process to Chinese authorities for regulatory testing with the goal of classifying the glass as non-hazardous waste product suitable for disposal in the Chinese market.
