U.S. PRIMARY ALUMINUM PRODUCTION Report for October 2021 Issued: November 10, 2021 Based on Aluminum Association surveys, the estimated annual rate of U.S. primary aluminum production totaled 924.0 thousand metric tons (kmt) during October 2021, a rise of 1.8 percent over the
Introduction. Aluminum, the most abundant metallic element in the earth's crust, is a light metal with excellent heat and electrical conductivity (Keith et al. 2008).By mass, 8.8% (88 g/kg) of the earth's crust is aluminum, and it can be found in numerous amounts of rocks (Keith et al. 2008).By the natural weathering of rocks, aluminum is …
