Brown corundum dust is a solid waste produced during the preparation of brown with bauxite as raw material. The has relatively high gallium content; therefore, it great value to recover from this kind dust. In paper, range analysis and characterization methods, including XRD, XRF, SEM-EDS, EPMA, were used determine occurrence gallium. It was found that mainly present in potassium-rich phase, wr...

Cocoa seeds were roasted at 120oC for 10 and 20 minutes were ground to a fine paste to obtain cocoa liquor. Cocoa fudge samples were prepared using the prepared liquor cocoa butter, sugar and lecithin. The two samples were analyzed for their physicochemical and sensory properties. The results of the study reveal that the roasting duration has a significant influence on both the properties. An i...

This work investigates the comprehensive recycling of graphite and cathode active materials (LiNi0.6Mn0.2Co0.2O2, abbreviated as NMC) from spent lithium-ion batteries via pretreatment flotation. Specific analytical methods (SPME-GC-MS Py-GC-MS) were utilized to identify trace relevant influencing factors. Two different methods, which are Fenton oxidation roasting, investigated with respect thei...

Carbothermic reduction-roasting tests of NCM (nickel, cobalt, and manganese) cathode active materials with carbon sources such as activated graphite followed by sulfuric acid leaching were performed to investigate the effects roasting temperature, molar mixing ratio sources, type materials. When virgin NCM622 roasted carbon, peaks Ni Co metals observed in XRD data. The efficiencies Li, Ni, Co, ...

Background and objectives: Sesame (Sesamum indicum L.) seeds have been a well-known oil crop in the world for many centuries. Lignans are functionally important compartments of sesame. Sesamin and sesamol are the main sesame lignans, which have recently shown various activities with health benefits, like anti-oxidative, anti-proliferative, anti-atherosclerotic, anti-in...
