2. Aluminium amalgam - Wikipedia

   en.wikipedia.org/wiki/Aluminium_amalgam

   The presence of water in the solution is reportedly necessary; the electron rich amalgam will oxidize aluminium and generate hydrogen gas from water, creating aluminium hydroxide (Al(OH) 3) and free mercury. The electrons from the aluminium reduce mercuric Hg 2+ ion [clarification needed] to metallic mercury. The metallic mercury can then form ...

3. Hall–Héroult process - Wikipedia

   en.wikipedia.org/wiki/Hall–Héroult_process

   Pure cryolite has a melting point of 1009 ± 1 °C (1848°F). With a small percentage of alumina dissolved in it, its melting point drops to about 1000 °C (1832°F). Besides having a relatively low melting point, cryolite is used as an electrolyte because, among other things, it also dissolves alumina well, conducts electricity, dissociates electrolytically at higher voltage than alumina, and ...

4. Aluminothermic reaction - Wikipedia

   en.wikipedia.org/wiki/Aluminothermic_reaction

   The oxide was heated with aluminium in a crucible in a furnace. The runaway reaction made it possible to produce only small quantities of material. Hans Goldschmidt improved the aluminothermic process between 1893 and 1898, by igniting the mixture of fine metal oxide and aluminium powder by a starter reaction without heating the mixture externally.

5. Aluminium smelting - Wikipedia

   en.wikipedia.org/wiki/Aluminium_smelting

   The anodes are manufactured by mixing aggregates with coal tar pitch to form a paste with a doughy consistency. This material is most often vibro-compacted but in some plants pressed. The green anode is then sintered at 1100–1200 °C for 300–400 hours, without graphitization , to increase its strength through decomposition and carbonization ...

6. Amalgam (chemistry) - Wikipedia

   en.wikipedia.org/wiki/Amalgam_(chemistry)

   Zinc amalgam finds use in organic synthesis (e.g., for the Clemmensen reduction). [3] It is the reducing agent in the Jones reductor, used in analytical chemistry.Formerly the zinc plates of dry batteries were amalgamated with a small amount of mercury to prevent deterioration in storage.

7. Mixing (process engineering) - Wikipedia

   en.wikipedia.org/wiki/Mixing_(process_engineering)

   Mixing of liquids occurs frequently in process engineering. The nature of liquids to blend determines the equipment used. Single-phase blending tends to involve low-shear, high-flow mixers to cause liquid engulfment, while multi-phase mixing generally requires the use of high-shear, low-flow mixers to create droplets of one liquid in laminar, turbulent or transitional flow regimes, depending ...

9. Bayer process - Wikipedia

   en.wikipedia.org/wiki/Bayer_process

   The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer.Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al 2 O 3), the rest being a mixture of silica, various iron oxides, and titanium dioxide.
