ABSTRACT:
Manganese is alloyed into aluminum using a solid compact prepared by blending finely divided particles comprising beta manganese with aluminum particles and then compacting the mixture into a readily useable form such as a briquette. The resultant briquette provides rapid dissolution of the beta manganese in the aluminum and improved manganese recoveries. The beta manganese may be prepared by heating manganese to 1305.degree.-1990.degree. F. followed by water quenching and crushing to obtain a product of controlled particle size having a reduced percentage of fines.
