Flotation studies of fluorite and barite with sodium
#0183;#32;The flotation results showed that SPS performed well in a wide pH region (711) even at a low temperature (5 #176;C), while the flotability of fluorite and barite were almost the same. At pH 11, the presence of SHMP obviously depressed fluorite rather than barite and SHMP exhibited good selective inhibition to fluorite.
