General description

Ammonium moly
BD
ate tetrahydrate (AMT) is a moly
BD
enum salt. Study of its extraction from nickel-moly
BD
enum (Ni–Mo) ore by direct hydrometallurgical method has been reported.
Its degradation by combustion to form elemental moly
BD
enum powder using metallic reducers has been investigated.
