|
DZ-Ni-EX-01 is mainly used for leaching the impurity metals of Cobalt, Manganese, Copper, Zinc and others from Laterite-Nickel ore, the loss of leaching Nickel is small, the exacted quantity of Calcium and Magnesium ion is little, will not be able to make precipitation to stop the equipment running in the working process. |

Dissolution and stability |
||||||||||||||||||||||||||||||||||||||||||||||
|
DZ-Ni-EX-02 must be used under pH6.2, the acidity of enrichment strip extraction should be kept below 180g/L. The extraction agent can keep stable and low water solubility. |
