摘要： A method for extracting cobalt from copper raffinate. First, a supply of raffinate containing at least cobalt, copper, ferric iron and nickel, is provided. The raffinate is pretreated by one or all of raising the raffinate pH level; removing solids; and, reducing ferric iron to ferrous iron. Substantially all copper is removed using first ion exchange resin selective for copper. A second ion exchange resin selective for both cobalt and nickel is used to remove the cobalt and nickel. Cobalt and nickel are separately eluted from the second ion exchange resin.

摘要： A method of regenerating N-Methyl-D-glu-camine-functional resin that has been used for boron-removal uses a closed recirculating loop for treating the conjugate acid salt of the N-Methyl-D-glucamine functionality of the resin. The new method reduces rinse water demand and improves pH control in a water treatment system. The new method can be used to improve the performance of boron-selective resins in stand-alone systems or as a second stage in a reverse osmosis seawater desalination system. The regeneration method is useful in any application where weakly basic anion exchange resin in the conjugate acid salt form is to be regenerated (neutralized) by alkaline treatment. Possible end use applications are in drinking water processing, agricultural water treatment, sweetener production, waste water processing, mining hydrometallurgy, and condensate polishing.
