Calcination Process Development Calcining Equipment

Equipment Used. Rotary kilns are used to carry out the calcination process. Depending on the process goals and the material to be processed, the kiln may be of the direct-fired, or indirect-fired type. It is also common to follow the calcination process with a rotary cooler. This efficiently cools the material after it has been calcined, so it ...

Global trends and environmental issues in nickel mining ...

2010-10-1  Nickel is commonly present in two principal ore types—sulfide or laterite. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt (Co), and often precious metals such as gold (Au) or platinum (Pt), palladium (Pd) and rhodium (Rh) (the platinum group metals or PGMs) (Naldrett, 2002, Hoatson et al., 2006).
