Mining Technology in the Nineteenth Century | ONE

After crushing or grinding, miners often used vibrating or shaking machines called concentrators (e.g., jigs, buddles, vanners, Embrey tables, and tables) to separate heavier metal-bearing ores from gangue. Flotation, which used "frothing" machines to mix air bubbles with oil and finely ground ore, emerged by the early twentieth century to do the same thing. Miners then shipped the ...
