"A quick series of trims featuring zinc mines in Katowice, Poland (Silesian region). The mine featured is the Giesche Zinc Mine and Refinery. VS in the mine, cars full of zinc being loaded and guided by workers, using levers to control the cars as they travel along the rails in the mine. CUs of the cars and zinc ore. Images are slightly underexposed due to the fact that filming was done in low light in an underground mine."@eng . . "Zinc mine and refinery in Katowice, Poland 1936"@eng . . .
