A resin and process for extracting non-ferrous metals. |
| abstract |
A process is provided for the direct recovery of non-ferrous metals (nickel, cobalt, copper etc) from raw materials such as ores, concentrates, semiproducts and/or solutions by ion exchange. A non-ferrous ore or concentrate is leached with a mineral acid to dissolve the metals. The pH of the resulting leach slurry is adjusted to 1.0 - 5.0 using some alkaline agents as limestone, sodium hydroxide etc. Non-ferrous metals are absorbed from this leach slurry with ion-exchange resin, which selectively loads the non-ferrous metals and has the structure: formula (1) wherein the ratio of N : M : P : R is within the ranges of 3-4 : 64-70 : 25-30 : 2-2.5 The loaded resin is separated from the exhausted leach slurry. The loaded sorbent is stripped with an acidic or ammonia-ammonium carbonate solution. The stripped resin is returned to the loading cycle. The non-ferrous metal can be recovered in substantially pure from the eluate by some known processes. The metal-depleted slurry proceeds to waste treatement and disposal. |
