General Information

For the HDS (NiMo/CoMo) and HDM (V/Mo/Ni) types of spent catalyst, we use hydrometallurgical as well as pyrometallurgical operations to obtain the highest possible yield of metal recovery. The oxides and concentrates (molybdenum and vanadium) produced meet, and even exceed, the standards found on the world markets today. The process recovers molybdenum, vanadium, cobalt, nickel and different types of alumina products, which can be reused in base metal, chemical and metallurgical applications. Moxba-Metrex products are of a chemical quality suitable for reuse by the major catalyst producer, fulfilling the full-loop recycling system.

The Company works with an on-site qualified laboratory, sampling and analyzing the incoming spent catalyst, in addition to monitoring quality control of the process and finished products.

Today, spent catalyst recycling is not the only service Moxba-Metrex provides. Complex turn-key projects with major oil refineries located worldwide are also our daily business. Services, including packaging, transportation and onsite sampling, are arranged from the moment the catalyst leaves the reactor through to completion of the finished products in our plants. Door-to-door transportation, with all necessary documents and notifications, is also included.
