of the Wadi Halfa low-grade iron ore. As a result of the fine dissemination of the iron minerals and the most abundant gangue mineral, quartz, the optimum degree of grinding is around 150 micrometers. The rougher tests of both the gravity separation and magnetic separation produced concentrates of about 44% Fe. Each of these two concentrates was cleaned in a second stage of processing
