Experimental Study on Preparation High-purity Cobalt Oxide and Cobalt Oxalate

Studying on some plant cobalt aqueous phase,it carried out high-purity cobalt oxide or cobalt oxalate preparation tests in the laboratory.Experimental results showed that using oxidation of iron,sodium fluoride to the depth of removing calcium and magnesium,oxalate or oxalic acid to precipitate cobalt,dryed and calcined such as steps from the aqueous phase to prepare high-purity cobalt oxide and cobalt oxalate,the product of the technical indicators is much better than an indicator of cobalt oxide materials.The recovery rate of cobalt of the entire process is over 95%.
