A method for preparing inorganic macromolecular flocculant by polymerizing silicate and zirconium tetrachloride is disclosed and relates to the field of feed water treatment. The invention aims at the problem of poor efficiency of inorganic low-molecular zirconium salt flocculant in treating low-temperature raw water and blockage of flocculation, by copolymerization of polymeric zirconium chloride and polysilicic acid, the SiOZr bond was formed to increase the molecular chain of the flocculant to strengthen the function of adsorption bridge and net capture sweep. Under low temperature, the flocculant can remove organic pollutants effectively, and the size of flocs formed is large and easy to precipitate. The invention is particularly suitable for the treatment of raw water at low temperature, low turbidity and high organics by enhanced coagulation.

The present invention relates to the recovery of rare earths, scandium, niobium, tantalum, zirconium, hafnium, titanium, and the like from ores or concentrates containing fluorine. More specifically, the ores or concentrates are pretreated by carbochlorination to convert the rare earths and other metals into their chlorides and then subjected to dilute hydrochloric acid leaching to recover the valuable rare earths and other metals from the leachate. Niobium, tantalum, zirconium, hafnium, and titanium can be recovered as their chlorides or oxychlorides from the gaseous products of carbochlorination, or converted into their oxides while simultaneously regenerating chlorine.
