2020-3-17 · High sulfide gold ore refers to 20% -30% of gold wrapped by sulfide (mainly pyrite). It is better to use gravity separation, flotation, or flotation-cyanidation process. The following is an analysis of specific beneficiation tests, and introduces four commonly ALACER GOLD TO PURSUE POX AS SULFIDE ORE ,2013-11-4 · In order to understand why POX is the best processing solution at Çöpler, it is important to appreciate the key characteristics of the refractory sulfide ore present at Çöpler. The highly refractory nature of the Çöpler sulfide ore means that poor gold recoveries result when using conventional cyanidization, even when fine grinding is applied. Gold recoveries using these non‐oxidative cyanidization processes are in the range of approximately 15% to 40%. Further test work during 2013 confirmed that flotation of Çöpler sulfides could recover 75% to 80% of the gold. This gold recovery, however, comes in the form of a relatively low‐grade concentrate at a relatively high mass pull meaning that flotation of the Çöpler sulfides produces a concentrate that is unattractive from marketing and logistical perspectives. Test work to improve concentrate grade through further flotation was unsuccessful due to a precipitous drop in gold recoveries.
2013-11-4 · As such, Alacer has focused on identifying the best oxidative processing method.
