摘要:A process was proposed to convert and separate selenium and arsenic in copper anode slime (CAS) by low-temperature alkali fusion process. Central composite design was employed to optimize the effective parameters, in which NaOH/CAS mass ratio, fusion temperature and fusion time w...

摘要:Abstract(#br)Synthesis of zeolite A using low grade Bombowha kaolin from Ethiopia has been carried out by two methods: the conventional hydrothermal synthesis and alkali fusion followed by hydrothermal treatment. In the synthesis process, the metakaolinization was achieved by...

摘要:... Alkali fusion of iridium was successfully performed using a vertical beam irradiation method and a mixed target of Ir and Na 2 O 2 , which resulted in easy dissolution of the irradiated iridium target. A trace amount of Pt Ⅳ Cl 6 2- was isolated from bulk Ir Ⅳ Cl 6 2-...

摘要:...9H 2 O and CaCl 2 during the alkali fusion process using NaOH was investigated by Raman spectroscopy in situ, X-ray diffraction and Fourier transform infrared spectrometer (FTIR). The results show that the tetrahedral silica chains within CaSiO 3 are gradually disrupted and tr...

摘要:... To improve the leaching efficiency of waste rare earth phosphor, a novel process of reduced alkali fusion followed by acid leaching to recover REEs from waste phosphor powder is proposed. Under the conditions of mass ratio of reductive iron powder to waste rare earth phospho...

摘要:... A simple alkali fusion method has been developed to prepare sodium silicate directly from sand and finally pure precipitated silica by acid precipitation. The reaction weight ratio of alkali to sand reaction parameters are studied for optimizing the silica yield. About 80% p...

摘要:Abstract(#br)An efficient alkali fusion–leaching–separation process is developed to recover metals in crushed metal enrichment (CME) which originated from waste printed circuit boards (PCBs). Impacts of fusion parameters on metals conversions were systematically investigate...

摘要:... The main steps for recovery include alkali fusion, recrystallization, hydrogen reducing and washing. First, W Re wire was decomposed by KOH-K 2 CO 3 molten salt to produce potassium perrhenate, where the decomposition ratios of W and Re reached 99.36% and 99.80% using a mas...
