Sulphide ores are concentrated by froth flotation process because pine oil selectively wets the sulphide ore and hence brings it to the froth What is the chemical formula for Tinstone Cassiterite also called tinstone heavy metallic hard tin dioxide SnO 2 that is the major ore of tin It is colourless when pure but brown or black when
