The production of iron ore at Sishen Mine began in June 1953, the ore being crushed and screened in a dry state. In 1961 a crushing and wet-screening plant was erected, and in 1963 the first heavy-medium beneficia-tion plant was commissioned. The production of iron ore for the Sishen-Saldanha Export Project began in 1976 after considerable expan-
The open pit mining load and haul system has been a mainstay of the mining industry for many years.
