Messi Biology said that the active magnesium oxide cobalt extraction process is a method for efficient recovery of cobalt from low-grade cobalt ore, using a combination process including leaching-iron removal-manganese removal-two-stage cobalt sinking process with self-produced cobalt sinking slag and two-in-one oxidizer to obtain qualified cobalt hydroxide, which realizes the utilization of low-grade cobalt ore resources. Compared with the existing technology, the activated magnesium oxide cobalt extraction process has the following advantages or effects.
1, using a combination of two-stage sinking cobalt slag and finely ground low-grade cobalt ore to remove iron, on the one hand, save the cost of iron removal chemicals and recover the cobalt in the two-stage sinking cobalt slag, on the other hand, most of the carbonic acid in the finely ground low-grade cobalt ore consumed in advance, so that when the iron removal neutralization slag is returned to the first step of leaching cobalt, the sulfuric acid dosage is greatly reduced.
2, the use of special oxidant for manganese removal, green, environmental protection, high efficiency of manganese removal and...
