GreenGold’s Operational Strategy is to provide a working environment that encourages cooperation between departments in both work and play. This video reflects the spirit of teamwork and features the miners at...
Each unique project has a specific solution depending on the ore type and environmental compliance conditions. The economics will vary with plant size, free cyanide levels, and solution chemistry. There is no simple answer, but there is an answer. The experience of the last 30 years has...
Cyanide is an excellent solvent, not only for non-refractory gold and silver, but also for some copper minerals. This has been seen as a negative attribute, especially for high copper ores where cyanide consumption is increased and it complicates the detox process. If the copper...
RECYN HISTORY Cyanide was first used in the 19th Century and has not been replaced in the 21st Century. More than 50 years ago, resin was proposed as an adsorbent to reduce free and metal complexed cyanides from gold plant tailings. The author of this paper has been involved...
Cyanide is firmly established in the gold industry as the overwhelming choice of solvent for gold and silver recovery from ores. Several niche applications for alternatives have been proposed, but it is unlikely the superiority of cyanide will be seriously challenged for some time. The reason...
Following its success at the Mirah project, the RECYN Technology has now been applied to a second project: the reborn Mt. Muro project which is also located in Central Kalimantan. This project has a similar mineralization to Mirah being high silver, low sulphidation, epithermal, narrow...
Engineering companies are entrusted with the task of designing and constructing process plants reflecting the best available technologies. In this capacity they have an advantage in persuading mining companies to implement new technology to enhance project economics. Historically the risk was arguably borne by the...
