scandium containing
63g / t Titanium tailings as raw material, adding a co-solvent hydrochloric acid extract scandium leaching rate of 93.64%; hydrolyzed with hydrochloric acid by alkali fusion scandium leaching, the leaching rate of 97.90%. The ruthenium was extracted by TBP, and the extraction rate was 98.90%; the water was stripped and refined with oxalic acid to obtain a Sc 2 O 3 product having a grade of 99.95%. Luo et al teach students with concentrated sulfuric acid decomposition reaction is autothermal tungsten slag smelting reduction, flooding scandium, rare earths, thorium, uranium, using P 204 -TBP- octanol synergistic extraction, further enrichment of scandium to 70-80%. The enriched material is dissolved in hydrochloric acid, into the color layer column of TBP extracting resin for chromatographic extraction, 6M HNO 3 is eluted, and then extracted with naphthenic acid to separate trace non-rare earth impurities such as calcium, iron , silicon and magnesium . After that, 99.999% of high-purity cerium oxide can be obtained.Corrosion-Resistance Alloy
Corrosion-resistance alloy,mainly refers to ordinary stainless steel resists atmosphere and sea water corrosion such as 300 series stainless steel including 304,316L, 317L etc.; comparatively strong corrosion resistance material including austenitic stainless steel 904L, 254SMOand Dual phase steel 2205,2507 etc.; corrosion resistant alloy containing Cu 20 alloy; In comparison to non-metal corrosion resistant materials, corrosion-resistance alloy main refers to iron alloy (resistance to corrosion); nickel alloy (Ni-Cr alloy, Ni-Cr-Mo alloy, Ni-Cu alloy and other active metal.
