Two gold heap leach operations -In Zimbabwe Springer
Gold recovery from Isabella ore averaged only 40% for the first six months of operation. This was attributed in part to the low grade ore fed to the pad and to the slow leach characteristics exhibited by the commercial heap. However, gold extraction from ore over the latter six months of 1990 has reached 70% and the upward trend continues.The implementation of mercury-free or at least mercury-restricted gold mining technologies is urgently needed to protect the biophysical environment and human health.3–6 Nevertheless, a new technology needs to be very convincing for miners to quit their traditional, easy, and effective amalgamation technology.7–9 A currently promising, Testing Local Conditions for the Introduction of a Mercury-free Gold

Visible gold was identified as 24.4%. Gold extraction tests revealed that the maximum gold extraction achieved by cyanidation was 85% using 250 mg/L NaCN, consistent with the gold deportment study. Similar gold recovery was observed using 0.03 M (NH 4) 2 S 2 O 3, but it reduced drastically in Na 2 S 2 O 3 leaching solution due to the In Zimbabwe, artisanal and small-scale mining (ASM) 1 has long been an important economic sector and a contentious arena for policymaking.
