Biotechnological Approaches to Facilitate Gold Recovery ...
Double refractory gold ore (DRGO) not only include ppt levels of gold grains locked in sulfide minerals but also a problematic amount of carbonaceous matter. This causes a significant recovery loss of gold during cyanidation because of the strong affinity of the Au(CN)2− with the carbonaceous matter. Combustion decreases the carbonaceous matter content, but also emits …

Gold Sluice Box Design - Mineral Processing & Metallurgy
For maximum recovery, the flow should be turbulent, yet not forceful enough to wash away the sand bed. Russian studies have shown that recovery increases with the frequency of cleanups. On one dredge, gold recovery was 90% for 12-hour gold cleanups and increased to 94% when sluices were cleaned every 2 hours (Zamyatin and others, 1975).
