praolahan bijih emas refraktori sulfidis melalui jalur proses hydrometalurgi. Kata kunci: bijih emas refraktori, pelindian, sianida, nitrit, oksidan INTRODUCTION Refractory sulfide gold ores are characterized by yield poor gold recovery in direct conventional cyanide leaching. That problem is an old and still existing problem until this time.
Sometimes gold deposits may contain a significant amount of copper or zinc, on the recovery process they form cyanide complexes that can be dissociate into weak cyanide, and be a competitor with ...
Mar 20, 2016· Pulp Densities. Pulp densities indicate by means of a tabulation the percentages of solids (or liquid-to-solid ratio) in a sample of pulp. This figure is valuable in two ways—directly, because for each unit process and operation in milling the optimum pulp density must be established and maintained, and indirectly, because certain important tonnage calculations are based on pulp density.
