👉 Platinisation is a chemical process that converts metals, such as iron or gold, into their platinum forms. This process involves adding a metal like lead, zinc, or copper to the surface of a solid material, which then reacts with oxygen and other elements in the air to form a platinized material. This platinization is typically used for the production of new metals that have been depleted by earlier processes, as well as for the recovery of materials from waste or contaminated environments.
