Barbotage is one of the most universal methods used for refining process of aluminium and its alloys. In this process tiny gas bubbles are generated and during their rising up to the surface the hydrogen is removed. In the same time some inclusions such as sodium, calcium and non-metallic particles, like oxides or borides can be also eliminated from the liquid metal due to flotation 1 . There a...

Aluminium is the world’s second most-used metal after steel and the aluminium production industry is the largest, in volume of metal produced, in non-ferrous metal industry. In this study, results of the material flows (country and global scales) related to the production and use of aluminium and energy consumption in 1980 to 2012 were separately analysed. Also, overview of the current status o...

Use of biomass as alternatives to petrochemicals has attracted a broad range of scientific and industrial interests. We propose here a novel environmentally-friendly recycle system for precious metal ions such as gold and platinum ions using protein-rich biomass. My keynote lecture is composed of three pieces; (1) selective adsorption of precious metal ions onto proteins, (2) the mechanism stud...
