Angelim Property – Zone 1 Initial Tests<br />
3 samples of 90 kg each were sent to NOMOS Laboratory for Initial Metallurgical Tests<br />
AMALGAMATION PROCESS:<br />
During this stage, chemical process<br />
simulates the physical activities of<br />
gravimetry.<br />
Au Head Cont: 22,11ppm<br />
Au Head Cont: 5,10 ppm<br />
Average recovery of the contained gold<br />
by gravity was 57%<br />
CYANIDATION PROCESS:<br />
The three samples analyzed recovered 90%<br />
of the Au, in particle sizes below 0.25 mm,<br />
in a period between 14 to 16 hours by<br />
cyanidation leaching.<br />
An ideal grinding granulometry of 0,150mm<br />
is taken as optimal, once the samples<br />
showed about 50% by weight in this size<br />
range (BS001-46,9%; BS002 59.47%; BS003-<br />
45,08%).<br />
Au Head Cont: 4,69 ppm<br />
Based on these characteristics, a small scale<br />
contained, closed loop CIL/CIP modular<br />
processing plant has been selected.<br />
