Design nickel solvent extraction plant for laterite nickel ore and so on

First, use D2EHPA to remove impurities;

Second, use DZ272 extractant to do the extraction process. Saponification of 45% at a temperature of around 50 ° C. According to the metal ion content of the feed liquid, configure an appropriate extractant concentration with a range of 10% -25%, and control the saponification temperature between 40 ° C-50 ° C. Then, mix and extract with the feed liquid, clarify and wash, reverse extract and regenerate with a suitable ratio, and repeatedly recycle.

Please communicate in detail with the technical personnel for the specific operation steps.

DZ-272 is applied to high content Ni-Co solution, also does not has extraction ability for calcium (Ca), can re-extract iron on the condition of low content sulfuric acid.

DZ-272 can be dissolved with fat diluent and aromatic diluent each other, and the stability is good, water-soluble ability is low.

DZ-272 can extract Ni-Co in the system of sulfuric acid and chloride, also can extract rare earth elements of gallium (Ga), molybdenum (Mo), germanium (Ge), thulium (Tm), ytterbium (Yb), lutetium (Lu) etc.

Advantage:

1. The effective component of DZ-272 can over 90%, has good extraction ability, high selectivity, low water-soluble ability, easy to be stripped.
2. The extraction step of DZ-272 is less, can save a lot of investment on equipment and hand work, will save much more cost.
3. The price of DZ-272 is lower than competitor very much.
