Abstract

Fremgangsmåte for å fremstille et metall, særpreget ved at fremgangsmåten omfatter oppvarming av råvarer som omfatter minst ett metalloksid og agglomerater omfattende et karbonholdig reduksjonsmiddel og herdet bindemiddel for å bevirke reduksjon av metalloksid til metall, idet hvert agglomerat har minst en støpt eller formet åpen kanal, og en tilsynelatende tetthet ikke større enn 99% av den tilsynelatende tettheten av et identisk agglomerat uten kanal.
