The development of cyanide milling at the end of the nineteenth century required grinding into smaller and more uniform sized particles using Chilean mills, ball mills, and tube mills. After crushing or grinding, miners often used vibrating or shaking machines called concentrators (e.g., jigs, buddles, vanners, Embrey tables, and tables
