There are many kinds of kilns that are used for minerals calcination. Rotary and shaft kilns are common equipment for this purpose. Roasting processes are used for producing oxide minerals from sulfide minerals like: lead, zinc and copper sulfide ores. Roasting is done in rotary or fluidized bed furnaces.
