对加拿大的三个金矿样进行了富氧氰化法试验。试验结果表明，使用氧能改善金的溶解动力学，减少磨矿时间并降低氰化物和石灰耗量。金提取率相同时，所需的氰化浸出时间从４８ｈ（矿浆含８ｐｐｍＯ２）减少到２４ｈ（矿浆含２０ｐｐｍＯ２）。氰化物耗量减少２３～３７％，石灰耗量减少３５～５４％。溶解的氧从２０ｐｐｍ进一步提高到３２ｐｐｍ时，效果不显著。在富氧矿浆中，＋２００目粒级的金提取率从４％提高到１４％。由三个金矿样的氰化得到的通用动力学模型可用下述方程式表示：Ｅ＝ＥＩ（１－ｅ）式中Ｅ是在时间ｔ（ｈ）时金的提取率（％），ＥＩ是最终金提取率（％），和ｋ是常数，它们取决于氰化物耗量、溶解氧的浓度和矿样的特性。对常规炭吸附和富氧矿浆中的炭吸附进行对比研究的结果表明，氧的富集会对金的吸附产生更有利的条件。
Three gold-bearing samples of Canada were tested for oxygen-enriched cyanation. Experimental results show that the use of oxygen can improve the kinetics of gold dissolution, reduce grinding time and reduce cyanide and lime consumption. When the gold extraction rate is the same, the required cyanidation leaching time is reduced from 48h (pulp containing 8ppmO2) to 24h (pulp containing 20ppmO2). Cyanide consumption decreased by 23 ~ 37%, lime consumption decreased by 35 ~ 54%. Dissolved oxygen further increased from 20ppm to 32ppm, the effect is not significant. In the oxygen-rich ore pulp, the gold extraction of + 200 mesh grade increased from 4% to 14%. The general kinetic model obtained from the three gold-like cyanidations can be represented by the following equation: E = EI (1-e) where E is the gold extraction rate (%) at time t The final gold extraction rate (%), and k are constants, depend on cyanide consumption, dissolved oxygen concentration, and mineral character. The results of the comparative studies on the carbon adsorption in conventional carbon adsorption and oxygen-rich pulp show that oxygen enrichment will produce more favorable conditions for gold adsorption.
