摘要: Abstract Restrictions in the proportion of recoverable cobalt from laterite ores Caron process are attributed to multiple effects. One these is adsorption solution species on precipitated iron oxide phase. Cobalt loss an precipitate produced ammoniacal carbonate was investigated. Adsorption experiments, both during and after precipitation, were conducted under a variety conditions. While prior research has focused more hematite, primary phase present residue found be ferrihydrite. Based significant differences capacity between various phases, material will make difference losses. minimised at low concentrations, pH 10 high ammonia while temperature (over range tested) did not display impact or
