Discrete Event Simulation of an Iron Ore Milling Process

The focus of this project is on simulating the interactions between interior components of a plant a discrete using event approach.An ordinary iron ore processing plant, with several comminution and separation stages, is considered for simulation. The system here involves a continuous process, but it is supposed to be modeled as discrete events.

Beneficiation of Iron Ores - IspatGuru

Iron ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 (70 % iron, hematite) or Fe3O4 (72 % iron. magnetite). Ores are normally associated with unwanted gangue material. Grade of iron ore is usually determined by the total Fe content in the ore.
