PROCESS FOR UPGRADING LOW RANK CARBONACEOUS MATERIAL

A process for upgrading brown coal and/or the recovery of metal values. The process includes providing two or more converging surfaces defining a nip therebetween wherein, at least one of said surfaces is rollable in a directi on toward said nip; feeding material to said nip where, by the rolling ac...

Beschreibung
Zusammenfassung:	A process for upgrading brown coal and/or the recovery of metal values. The process includes providing two or more converging surfaces defining a nip therebetween wherein, at least one of said surfaces is rollable in a directi on toward said nip; feeding material to said nip where, by the rolling action o f the rollable surface, under shear stresses the material forms a plastic mass . The invention also extends to a process for the production of char and/or metal char composites, with the optional recovery of metal values, by heatin g pellets formed from the upgraded brown coal process.
