2017-10-10  The effect of coke on the grades and recoveries of nickel, cobalt and iron was investigated by using coke in the range of 0.4–3.2 wt% of the roasted ore. A charge of 25 g of the roasted ore, 9.4 g Na 2 B 4 O 7 10H 2 O, 13.8 g Na 2 CO 3 , 4 g SiO 2 , and 3 g sulfur was used as the smelting

2012-11-23  For example, 100% cobalt was recovered by adding 5g spent catalyst, but the recovery decreased to 97.4%, 92.9% and 82.3% respectively with addition of 10g, 15g and 20g of spent catalyst. It is due to the reason that cobalt in spent catalyst is cobalt oxide form (Park 2001) and more coke is required to reduce it as cobalt metal.
