Extracting bismuth from other raw materials

Zhang Zonghua 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.

Aluminum Air Battery

The aluminum air battery application can widely use in the field like civil, industrial and military, mainly use for emergency energy for house/ hotel / hospital/ fire control/ public area emergency light, power bank for phone and computer, barn lantern, standby power of building, communication base station, emergency rescue,refuge park, mine, camping, field training, field power supply, charging, maintenance, lighting requirements. The aluminum-air battery uses high-purity aluminum (containing 99.99% aluminum) as the negative electrode, oxygen as the positive electrode, and potassium hydroxide (KOH) or sodium hydroxide (NaOH) aqueous solution as the electrolyte . Aluminum ingests oxygen in the air and produces a chemical reaction when the battery is discharged. Aluminum and oxygen are converted into aluminum oxide.
