Anglo Gold Ashanti Achieves Improved Product Flow And Control
Anglo Gold Ashanti is headquartered in Johannesburg, South Africa. It has twenty operations in ten countries on four continents, all focusing on gold mining. The Moab Khotsong mine in South Africa contributes 16.4% of gold ore to AGA South African operations. Anglo Gold Ashanti storage silos are 10 m (32.8 ft.) wide and 22 m (72.2 ft.) high, and can contain up to 10,000 tons of material.
Good inventory control is essential because the gold ore has a high raw material cost. AGA South had difficulties with the volume control of a silo used for gold ore. The silo has Grizzly Bars at the bottom that must have a minimum level of material coverage to protect it from falling rocks and gravel entering the silo. They also needed to be able to ensure there was an adequate supply of gold ore for production.
