Aluminum's dangerous dependency on China's smelter sector

The only times aluminum supply surprises is when a smelter loses power for long enough a time that the molten metal solidifies in the potlines requiring a lengthy restart process.

Alcoa, Rio Tinto and Apple work with Canada to erase

The smelting process accounts for about 17 percent of greenhouse gas emissions from the aluminum industry and 1 percent of total global CO2 emissions. Historically, the smelting process removes oxygen from aluminum oxide, also known as alumina, by mixing the raw material with cryolite, which includes molten salts, and applying a strong

Environmental Guidelines for Aluminum Manufacturing

Soderberg technology for aluminum smelting is a significant pollution prevention measure. In the smelter computer controls and point feeding of aluminum oxide to the centerline of the cell help reduce emissions including organic fluorides (e.g. CF4 reductions to <0.1 kg/t aluminum). Energy consumption is typically 14 megawatts

Primary Aluminum Reduction Industry - National Emission

Primary aluminum reduction plants electrolytically reduce refined bauxite to form aluminum. Once formed, the aluminum may be processed via casting (pouring molten aluminum into a mold), rolling, extrusion, etc. to meet the shape, strength and durability requirements of its final use.

Impacts of Smelting - Base Metal Smelting

Smelting is known to be a major cause of pollution in the environment. When smelting occurs, along with the metal produced, a solid waste product, called stag, is also produced. This slag is emitted into the air and can be a cause of the pollution although not a major one. The majority of the pollution is caused by air emissions.
