Industrial Processing of Perlite. The industrial processing of perlite involves mining the raw material from volcanic deposits, followed by crushing and grinding to achieve the desired particle size. After processing, perlite is subjected to intense heat at temperatures of around 900-1100°C (1652-2012°F) in a furnace.Web
