Roasting process and thermal dissociative kinetics of the svanbergite

Sichuan Province in China is endowed with abundant svanbergite resources, which are one of the biggest mineral deposits of aluminium phosphate-type in the world. The svanbergite is the immediate roof of the lower layer-huge phosphate rock. So the utilization of svanbergite deposit should be solved before exploitation of the huge phosphate rock, otherwise it will waste phosphate resources and pollute environment.
