The effects of (a) particle size ranging from 63 to 250 μm (b) stirring speed ranging from 180 to 540 min1 (c) acid concentration ranging from to M (d) temperature ranging from 30 to 90 ° on the leaching of iron and manganese are reported. The leaching rates were significantly dependent on the particle size of the ore, stirring speed, temperature, concentration and the nature of the acids used.
As an alloy, it decreases the brittleness of steel and imparts strength. The amount of manganese used per ton of steel is rather small, ranging from 6 to 9 kilograms. About 30 percent of that is used during refinement of iron ore, and the remaining 70 percent is used as an alloy in the final steel product.
