WO2004022795A1 Process for recovering platinum group

The process of the present invention recovers platinum group metal(s), such as platinum and palladium, from PGM-containing materials containing base metals, such as copper and nickel. The process controls sulfur levels by using solvent extraction (306) to remove acid in the nickel recovery circuit. The acid product (326) can then be neutralized and/or recycled as desired.
