Rockdale was the site of a large Alcoa aluminium smelting facility, which could produce 1.67 million pounds of aluminum per day.[7] The Alcoa plant profoundly changed the city, as noted in a Saturday Evening Post article by Rockdale native George Sessions Perry. Within a few years of its arrival in 1952, Rockdale almost doubled in population, changing in character from a predominantly agricultural economy to one heavily driven by manufacturing jobs. Smelting operations were halted at the Alcoa plant in 2008.[8] The Alcoa plant closed in February 2014 when production at the atomizer ceased.[9]
Rockdale was also the site of the Sandow Power Plant,[10] which closed in 2018.[11] [12]
Two cryptocurrency miners, Bitdeer, a division of Bitmain, and Riot Blockchain, formerly known as Bioptix, occupy former Alcoa facilities less than half a mile apart in Rockdale, using electricity transmission lines built to connect smelters to the power plant.[12] [13]
