choices some  of good silicon metal plants and Ferrosilicon factories in China,   put the machines collect  the byproducts - microsilica (silica fume) ,it can be  protect environment ,also  the  looks like  rubbish ash became valuable materials.  it  used in concrete , refractory , highways and marine structures etc.
