Recycling and Purification Process of Chloroplatinic Acid Waste Incorporating Platinum Metals Prices

The recycling process of chloroplatinic acid waste involves many intricate steps to ensure the high-purity recovery of platinum. The entire recycling flow consists of several key stages: dissolution, reduction, refining, and purification.

Chloroplatinic acid waste is initially treated by dissolving in water to form a platinum-containing solution. In our practical dissolution process, insoluble impurities may be generated, which need to be removed through physical methods such as filtration or centrifugation. Subsequently, a reducing agent is added to the solution, and by controlling the solution’s pH, temperature, type, and concentration of the reducing agent, platinum particles can be precipitated.

After the precipitation of platinum particles, the metallic platinum is separated from the solution through filtration or centrifugation, yielding platinum powder. Then, the platinum powder is purified using acid washing, solvent extraction, and high-temperature calcination.

The recycling steps for chloroplatinic acid do not end after purifying the platinum powder. We further process it in a high-frequency furnace, melting it into platinum metal blocks according to different requirements, integrating considerations of platinum metals prices into the process.
