In the nickel-cobalt extraction unit, what is the typical O/A ratio for a single stage? (Not always the O/A ratio)

Thread Content

In actual industrial nickel-cobalt extraction processes, the extraction stage involves multiple stages of extraction; if there are 4 such stages, and the overall O/A ratio is too high, then the O/A ratio for each individual stage is adjusted by increasing the reflux of either the oil phase or the water phase. May I ask, what is the typical value of the \"single-stage O/A ratio\" in the extraction section (not the overall O/A ratio)?
