What is the difference between P507 and C272?
Thread Content
I would like to ask the experts: the metal contents in the solution are roughly as follows: Ni, Co, Cu, Fe, Mn – 62.26, 0.389, 0.438, 0.0019, 0.908; 64.46, 0.385, 0.292, 0.0054, 0.0164; 64.62, 0.362, 0.798, 0.378, 0.0157; 61.24, 0.364, 0.614, 0.102, 0.0162. First, impurities need to be removed using 204; which extractant would be suitable for use thereafter? What are the advantages and disadvantages of 507 and 272 in industrial applications?
507 for low investment, 272 for high investment. 272 has a high nickel-cobalt separation coefficient and a short number of extraction stages. At this cobalt content of 507, the cobalt sulfate solution produced has a high nickel content. 272 can also remove magnesium from nickel sulfate
Thank you, I mainly want to extract cobalt from the nickel sulfate solution. A pure nickel sulfate product is obtained; the purity of cobalt sulfate is not considered for now, as its amount is too small. It’s not clear whether using 507 can achieve complete separation of cobalt Mainly, the concentration of cobalt is too low.
There is no problem with 507 Cobalt extraction at all.
507 is fine! C272 is mainly used for high-purity nickel sulfate – it’s too expensive!
272 is used for high-purity nickel, but it is very expensive; moreover, its saponification is greatly affected by environmental temperature, which makes it difficult to operate processes using 272
