Avnel Gold Reports That Indicated Resources
because of the larger mass and volume being assayed, leachwell is a more appropriate method than fire assay for determining gold content at kalana. As a result of the success of previous leachwell re-assay programs at kalana main, the company plans to submit approximately 6,000 existing samples from this zone for leachwell analysis, which isjun 24, 2015 cyanide leach test procedure. bottle leach procedure for cyanidation.. Be sure to use at least but per test is better. Be sure to use a big enough bottle.dec 01, 2015 lower extraction of silver than gold in conventional cyanidation process has been commonly observed in practice. acanthite is one of the typical silver minerals with low solubility in aqueous cyanide medium, which contributes to low overall silver extraction. the performance of different auxiliary oxidants, including hydrogen peroxide calcium peroxide and leachwell
