nepheline ore yields 1 tonne of alumina, 9–11 tonnes of cement, 0.6–0.8 tonnes of soda ash, and 0.2–0.3 tonnes of potash. According to the grade of the bauxite ore, 2–3 tonnes of ore yield one tonne of alumina and about one tonne of red mud (dry weight). When designing an alumina plant, factors

The weathered ore is intensely scrubbed to break down the soft fractions and then screened as shown. All the —1½" ore is wet screened to produce +10 mesh and —10 mesh sizes. The — 1½", +10 mesh fraction goes to a heavy media separator from which the sink product, after media screening and washing, goes to concentrate storage.

crushed and screened for a final time, then the fines are recycled, and the product is sent to be charged to the blast furnaces. Generally, 2.3 Mg (2.5 tons) of raw materials, including water and fuel, are required to produce 0.9 Mg (1 ton) of product sinter. 12.5.1.2 Iron Production -

The pyrometallurgical process flow sheet comprises drying and calcining of the laterite ore and blending with the separately dried and calcined NIP. Drying is carried out at around 130–150 °C in separate rotary driers sized for the different amounts and based on the thermal characteristics of the two feed materials.

The Mineral Processing Flowsheets shown on the following pages are based on actual data obtained from successful operating plants. Metallurgical data are shown in these flowsheets which incorporate Crushers, Grinding Mills, Flotation Machines, Unit Flotation Cells, and Selective Mineral Jigs as well as other standard milling equipment. The Flotation Machine, the Selective Mineral Jig and ...
