|Processing the rock|
Ore processing: the gold-bearing rock is transported by rail or conveyor belt to the plant for processing. At the plant, the ore is crushed and then milled to a fine powder. Gold is then extracted from waste using chemicals.
Pictured here: rotary mills in the No.1 West Wits metallurgical plant which crushes the ore into smaller particles.
