Disclosed are processes and electrolytic cells that can be used to extract and thereby recover aluminum from aluminum-containing waste, including an aluminum dross that is suitable for disposal in a land-fill. The disclosed processes and cells use ionic liquids as an electrolyte.

Aluminum recovery process

Lightweight and reactive metals can be produced from ore, refined from alloy, and recycled from metal matrix composites using electrolysis in electrolytes including an ionic liquid containing a metal chloride at or near room temperature. Low electric energy consumption and pollutant emission, easy operation and low production costs are achieved.

Production, refining and recycling of lightweight and reactive metals in ionic liquids

A temperature sensor having a capillary tube or stem, sealed at both ends, with a thin bore defined therein is applied to the measurement of temperatures having a range of about &minus;100&deg; to &plus;400&deg; Centigrade. A bulb comprising a liquid reservoir, is provided at one end of the capillary tube, in liquid communication with the bore, and is generally filled with an ionic thermometric liquid. In the operation of the temperature sensor, temperature is measured by the height of the liquid in the bore.

Ionic liquid temperature sensor

A method of making metal/refractory composites includes bubbling a reactive gas through a melt to form a foam including refractory particles. In continuous mode, the foam is separated from the melt and the melt replenished. Composites of lightweight metals reinforced with discontinuous refractory ceramic particles can be efficiently and economically produced.
