AMCO OTOPENI

Precious metals recovery and refinary : Platinum; Rhodium; Palladium

The recoveries are made by hydrometallurgical and chemical processes, from waste materials with precious metals content ( Pt; Rh; Au; Pd; Ag).

The scraps can be from spent catalysts, precious metals objects, electronic scrap, jewels, others.

The client opportunities to dispose the precious metals are:

• The recovered precious metals return to client in pure form ( powder or ingots)

• The precious metals are buyed by AMCO OTOPENI S.A.

• Initiating a metal account for the client, with all time availability, to use the metal for final products made by AMCO OTOPENI S.A. or others.
