NANOSTRUCK ANNOUNCES 87.6% RECOVERY OF 56 GMS/TON SILVER TAILINGS SAMPLES
Nanostruck Technologies Inc. has provided positive results
from test work carried out on silver mine tailings utilizing proprietary
cyanide-free recovery technologies that returned up to 87.6 per cent of silver
from samples grading 56 grams of silver per metric tonne (g/t).
Three leach tests were conducted using the proprietary mixed acid leach
process. Roasting was conducted on the sample for two of the leach
tests, producing higher recoveries, although the unroasted sample still
produced a 71-per-cent recovery rate.
-
87.6-per-cent silver recoveries resulted from a four-hour leach time at 95
C, with the standard feed grind size of D80 175 microns of
roasted material;
-
84.3-per-cent recoveries resulted from a four-hour leach at 95 C with the standard feed grind size of D80 175 microns with roasted
material at a lower acid concentration;
-
71-per-cent recoveries resulted from a four-hour leach at 95 C from received material, with the standard feed grind size of D80 175
microns with an altered acid mix concentration.
The average recovery for the roasted samples was 86 per cent across the two
leach tests performed using the proprietary process.
Bundeep Singh Rangar, interim chief executive officer and chairman of the board, said:
"These results further underpin the effectiveness of our processing
technology. With our patented process we are achieving excellent
recoveries in not only silver tailings, but also gold tailings as well,
both of which have vast global markets for us."
The proprietary process combines a novel mixed acid leach with a solvent
extraction stage, utilizing specific organic compounds. No cyanide is
used in this environmentally friendly process. The flow sheet design is
for a closed loop, sealed unit in which all chemicals are then recycled.
Previous test work undertaken on other gold mine tailings utilizing the
proprietary process resulted in a maximum 96.1-per-cent recovery of gold.
Previous test work undertaken on other silver tailings resulted in a
maximum 86.4-per-cent recovery of silver.
