I used spent half an year visiting accompany with clients in welding flux raw material sourcing like bauxite, MGO, CaF2..., and found that the concentrated location of factories are in Gongyi,Henan, but the furnace and powder processing is separated, no supplier is in both of them. and the furnace there are shaft. another 2 cities are Yangquan, Shanxi and Tianjin, the mineral stones are almost from Yangquan to Tianjin for powder processing, and there are rotary furnaces in Yangquan.
