Mine Planning and Grade Control - Goldsworthy
Organization: The Australasian Institute of Mining and Metallurgy
Jan 1, 1973
Goldsworthy Mining Limited is currently mining iron ore at an annual rate of 7 million tons from several small orebodies, each of which exhibit wide variations in iron, phosphorus, silica and alumina contents. Each orebody is mined at its average ore reserve grade and therefore mine planning and grade control techniques have had to be tailored to achieve a constant production blend.
