Implementing a newly invented environmentally friendly process to the noble metal industry, for the recycling, extraction and refining of target metals, could prevent the common daily use of the hazardous processes involved in the precipitation-electrodeposit and strong acid procedures. The new method, using chemical substances with rather low boiling temperature in ambient pressure, without any toxic, dangerous or explosive substances, is achieved by the production of an effective and controllable system of oxidative dissolution, which is applied at the solid state solution and is related to the electron transfer via charged-transfer complexes and ion-radical states. The result is a high selectivity and velocity process, which is extremely efficient and valuable.
