Efficient Refinement Process for Platinum from Chloroplatinic Acid Waste Incorporating Platinum Metals Prices

How can chloroplatinic acid be recycled? Extracting platinum from chloroplatinic acid waste is an extremely complex process. Below, Hirakawa Precious Metals will guide you through the recovery methods for chloroplatinic acid, hoping that after reading this content, it will bring help to everyone.
Platinum group metal
The waste needs to be dissolved in water to form a solution for further processing. The key in this step is to fully convert the platinum into a dissolved state, preparing for the subsequent reduction reaction. The next step is the chemical reduction of platinum, with reducing agents like sodium formate added to achieve its reduction. The platinum ions in the solution are reduced to the form of metallic platinum and precipitate out as fine particles.

The precipitated metallic platinum then needs to be separated, usually through filtering or centrifugation. The separated platinum still contains certain impurities and requires further purification. The purification process may include solvent extraction, acid washing, and other steps to remove non-platinum metal impurities.

Finally, the platinum is further purified by high-temperature calcination to remove organic impurities, thus successfully recovering the platinum from chloroplatinic acid, while also considering the impact of platinum metals prices on the recovery process.
