摘要
The present invention leaches platinum groups from industrial waste containing platinum group metals (platinum (Pt), ruthenium (Ru), osmium (Os), rhodium (Rh), iridium (Ir), palladium (Pd)), adsorbs onto an absorbent platinum group metal ions inside a leachate, desorbs the platinum group metal ions attached to the adsorbent using a desorbent to recover high concentration platinum group metal ion mixed solution, and also, recover the platinum group metal ions in the metallic form by ashing the adsorbent having the platinum group metal ions attached thereto. In addition, the platinum dissolved through a dissolving process from the ash mixed with the platinum group metals after the ashing process can be recovered as high concentration platinum ion, and undissolved ruthenium can be isolated in a metallic form.
