NEWLOX GOLD HIGHLIGHTS INNOVATIVE NON-TOXIC GOLD TECHNOLOGY
Newlox Gold Ventures Corp.
is highlighting a
recent academic paper
written by: Pariya Torkaman from the Norman B. Keevil Institute of Mining Engineering, University of British Columbia; Akihiro Yoshimura from the Graduate School of Science and Engineering, Chiba University; Leslie M. Lavkulich from the Department of Land and Food Systems, University of British Columbia; and
Dr. Marcello M. Veiga,
on the topic of innovative gold-leaching process using a non-toxic organic reagents.
This recent study tested dimethyl sulphoxide, a water-free lixiviant that extracts gold from ores/concentrates in combination with copper halides, on a sample of high-grade gold ore from Colombia, with impressive results. The team found that 96.5 per cent of the gold was extracted from the samples in two hours at room temperature, a finding that exceeds the control test of a typical cyanidation test, which achieved 97 per cent gold extraction in 24 hours at ambient temperature. Gold dissolved by the new technology was successfully precipitated and recovered, while the reagent could be recycled through a distillation process.
The full paper can be accessed on-line.
This recent testing by Ms. Torkaman and her colleagues echoes the encouraging results previously obtained by Newlox Gold using a similar process. The Newlox R&D (research and development) team has previously achieved excellent gold recoveries of nearly 100-per-cent recovery at 80 degrees Celsius and over 90-per-cent recovery at ambient temperature during lab testing. Newlox Gold plans to continue to develop this innovative technology. The company has secured a supply of the necessary reagents, and plans to begin in-field testing a similar process which could replace cyanide and mercury in the mining industry.
