The application of RE Products in metallurgical / petrochemical and eletronic industries is described systematically.

This paper briefly describes the recent research and development of rare metalcontaining ceramic pigments and glazes. Some related literatures are presented for reference.

SP-700 Ti alloy features better forgeability, longer service life and lower cost than the conventional Ti alloy. It has found some applications in the fields of sports goods, hand tools and watch-making, etc. It is expected to extend its application to the steam turbine blades industry.

The extraction of molybdenum (Ⅵ) from nitric acid solution by primary amineN1923 in octane has been investigated at 298K. The equilibrium expressions at lower and higherPH values were proposed respectively. The equilibrium constants were calculated.

Solvent extraction of Sc was investigated experimentally The extraction systemconsisted of P2O4, twroving agent, and kerosene. The results show that the extraction rates ofSc can reach up to 99. 7 %, the removing rates of Fe and Mn are 98. 1 % and 99. 3 % respectively,the stripping rates from organic phase with NaOH reach up to 99.6% with effective separationfrom Fe and Mn.

Study is made on the upgrading of Co from low-grade concentrate calcine leachateand its separation from impurities. The studied leachate is free of Fe and Cu, with Co contentonly about 1 g/L while the impurities such as Mg. an. Ni. Mn. St etc in it are about ten times asmuch as Cab. After absorption by absorbent and then processing by HCl at room temperature, thecontent of Co in Hcf solution is about 13 g/L, and Co in the effluent is less than 1 mg/L. Afterevaporating and concentration. Co could be upgraded to over 20 g/L in the enriched solution andseparated from Si. The total recovery of Co to rich Co solution could reach as much as 98. 7%.Then extracted by N235 to separate impuritys CoC12 could reach the technical-purity standard.

For possible application of the titanium based β-PbO2 electrode in tungstenhydrometallurgy industry, its electrochemical property in alkalinous sodium tungstate solution hasbeen studied.

This paper describes the distribution of In, Ga, Ge and Cd in oxygen pressure acidleaching process of Cu-Zn-Ph bulk flotation concentrate. The result shows that the raremetaishave been leached out and concentrated in varying degrees in intermediate products from recoveryof Cu and Zn. The paper also discusses metals recovery process.

Study is made on Ge recovery from H2SO4-leached supernatant (0. 02 ～0' 03 g/lGe), using 'H' kerosene and butyl octano TBP as extractant. Resljlts show that the said processfeatures lower reagent consumption and over 22% Ge content in concentrate.
