Refined Iridium Recovery Process - Chemical Precipitation Method#Iridium The chemical precipitation method in the field of iridium recovery is like a precisely controlled chemical performance, providing an ideal platform for the efficient recovery and purification of iridium. The essence of this method is to place iridium-containing waste in an appropriate acidic environment to induce ionization of iridium, and then initiate the precipitation of iridium ions into a solid through a carefully sele
