Palladium Refining Tutorial-Part 1
Palladium (Pd) refining can be a daunting task, similar to the other Platinum group metals (PGM''s) refining process. This is mainly due to their similar (but different) physical and chemical properties. Separating Palladium from base metals and especially from sister PGM''s, is rarely achieved completely in one refining cycle. Sounds kind of rough, but rest assured that this process is doable ...
The Properties and Applications of Platinum
· The first step in this process is to crush platinum containing ore and immerse it in the reagent containing water; a process known as ''froth flotation''. During flotation, air is pumped through the ore-water slurry. Platinum particles chemically attach on to the oxygen and rise to the surface in a froth that is skimmed off for further refining.
Metal values are recovered from ore concentrates by means of dry grinding, followed by a two-stage leaching process in which the ground concentrate is first leached with sulfuric acid at a temperature of about 90° to 100° C. to selectively leach nickel and iron. The residue is then leached with a solution comprising sulfuric acid and NaOCl or H 2 O 2 to extract platinum, palladium, copper ...
