New technology for briquetting of manganese concentrate
IC ECOENERGY has developed a technology for briquetting of manganese concentrate. Relationship between briquette firmness and the amount of binder consumption, compacting pressure, as well as the temperature and time of drying, has been specified. The most optimal material compositions of briquettes for ferroalloy production (ferromanganese and silicomanganese for needs of metallurgical plants) have been chosen.
In the course of the research, a number of batch compositions with different kinds of binders, as well as methods of their mixing, were worked out. After having been tested for impact, drop and abradability resistance etc, several variants, which were acknowledged the most successful ones, were recommended for industrial briquette manufacturing. The research of thermal ore processes preceding the melting point has also been conducted. Its results have proved the possibility of application of briquettes as raw material for ferroalloy production.
