The high gold recovery observed in the grindingclassification section of the plant is commonly explained by the inherent high initial dissolution rate of gold observed in gold ore cyanidation, or by the intense agitation prevailing in grinding mills.

Jun 29, 19930183;32;Hitherto, there have existed two principal methods of recovering gold from gold ores or gold concentrates. The first method involves cyanidation followed by the Merill Crowe process wherein gold is recovered from solution by cementation with zinc powder which must then be refined to obtain gold

Analysis of the gold recovery profile through a cyanidation plant The high gold recovery observed in the grindingclassification section of the plant is commonly explained by the inherent high initial dissolution rate of gold observed in gold ore cyanidation, or by the intense agitation prevailing in grinding mills.
the percentage gold dissolution depends more on the ore size consists than on the cyanide concentration with the highest average dissolution rates of 88.75, 94.34 and 95.90% found at 600, 500 and 500 ppm, for 60, 70 and 80% passing sizes, respectively.

One possible processing technique for PGM recovery from oxidic ores is cyanidation process which has been proven to be effective for extraction of gold and silver by direct leaching of oxidic ores/concentrates .
Rocks Minerals went to its present peer review system, was redesigned into a larger (20x28 cm) format, and became a bimonthly publication. Marie Huizing, of Cincinnati, Ohio, became the managing editor in 1978, a position she continues to hold to this day, of Rocks Minerals.
metallurgy of gold, the cyanid process is coming under pressure. Increasing importance of refractory gold ores, together withthe growing concern about the environmental impact of cyanid containing discharges, have given r e newed impetus to research and development into alternative leaching methods of gold ores.

The total iron content of most exported iron ores in the world is in the range of 6264% . Therefore, the average quality of iron ores from the five locations of Katse deposit is above and comparable with the best iron ores nations hence are among the world high grade ores which can be exploited.
