the aluminum industry in the united states in 2014 produced 1.72 million metric tons of primary aluminum, worth 3.97 billion dollars, at nine aluminum smelters. in addition, the us produced 1.70 million tons of secondary aluminum from old post-consumer scrap, and 1.93 million tons of aluminum from new manufacturing scrap.
bismuth antimonides, bismuth-antimonys, or bismuth-antimony alloys, bi 1−x sb x are binary alloys of bismuth and antimony in various ratios.. some, in particular bi 0.9 sb 0.1, were the first experimentally-observed three-dimensional topological insulators, materials that have conducting surface states but have an insulating interior.. various bisb alloys also superconduct at low .
dross refers to the lead oxides, copper, antimony and other elements that float to the top of the lead. dross is usually skimmed off and sent to a dross furnace to recover the non-lead components which are sold to other metal manufacturers. the parkes process is used to separate silver or gold from lead. finally, the molten lead is refined.
the bunker hill mine and smelting complex 'bunker hill smelter' , was a large smelter located in kellogg, idaho, in the coeur d'alene basin.when built, it was the largest smelting facility in the world. it is located in what became known as the silver valley of the coeur d'alene basin, an area for a century that was a center of extensive silver and other metal mining and processing.
a cast bullet is made by allowing molten metal to solidify in a mold.most cast bullets are made of lead alloyed with tin and antimony; but zinc alloys have been used when lead is scarce, and may be used again in response to concerns about lead toxicity. most commercial bullet manufacturers use swaging in preference to casting, but bullet casting remains popular with handloaders.
