With the rising gold prices in recent years, it further stimulated the rapid development of gold industry. As the exhaustion of high-grade gold ore, researching on middle-low grade and refractory gold ore and strengthen the traditional gold mining process undoubtedly have become the main trend in global gold beneficiation industry.
In March 2015, Xinhai contracted to build Zimbabwe 700tpd gold processing plant in Africa. The raw ore of this mine is quartzite gold mine, which is most oxidized ore or original minerals with low sulfur content. Therefore the processing technology is combined gravity separation and all-slime cyanidation carbon-leaching technology, which ...

May 01, 2015 Plant design parameters for gold extraction, leach residence time and cyanide consumption are generally determined from standard bench-scale bottle roll or agitation leach tests. The application of laboratory data to process design has essentially evolved from the testing of oxide or low cyanide-consuming ores. Such scale-up factors may not be appropriate for ores that deplete
The Union Reefs Gold Mine (URGM) plant underwent an expansion in late 1997 and as the mine matured and the plant throughput was increased to around 2.7 mtpa through 1998 the transition was made from predominantly oxide to primary ore. As the year progressed the gravity recovery decreased and metallurgical problems increased.
