Separation of Scandium and Calcium by Liquid-Liquid Extraction using Tri-N-Butyl Phosphate as Solvent
<p>Equilibrium data have been obtained for the systems Ca(N03)2- HNO3- TBP- H20 and Sc(N03)3- Ca(N03)2- HNO3- TBP- H20 over a wide range of concentration of the metal nitrates in the aqueous solution. Equilibrium acid concentration was used as a parameter for the equilibrium curves.</p><p>For the …

Studies on the Chemistry of Human Hemoglobin
… the confirmation of adult human hemoglobin in solution. It is now well established that one form of the hemoglobin molecule is composed of four polypeptide chains, two α chains, and two β chains, held together by non-covalent bonds. The linear sequence of amino acids in both the α chains and …

An investigation of cyanide-based heap leaching for extracting precious metals from Platreef ore
… a suitable oxidant that can be used in cyanide solutions, from among air, oxygen and ferricyanide, to facilitate the dissolution. Various tests using sperrylite mineral samples micronized to 5 μm in batch stirred tank reactors (BSTR) at 50°C were conducted. It was found that a combination of …

Investigating the role of dithiophosphate in the flotation of base metal sulfides
… used to investigate the effect that SEDTP had on equilibrium surface tension. This was compared to the surface tension of a polypropylene glycol (PPG) frother, which was selected as a benchmark due to it being a surface active agent at the air-water interface and its general use in the industry as …
