The key objectives of the evaluation are as follows: Assessment of different eco-efficient comminution process circuits to treat magnetite iron ore. Determination of the process operating costs and the capital costs for each process route. Comparison of the benefits of the different process routes from an economics point of view.
The iron ore pellet feed concentrate exits the beneficiation process as a pulp or high moisture content concentrate. A further size reduction therefore needs to be carried out wet to avoid drying costs, or dry if a low moisture content and local energy costs do allow for an economic drying process route.
The waste water from iron ore slurry is separated through filtration system and treated in the thickener. In the thickener, all de-dusting/scrubber return water is passed and the underflow is reused in the process. The pellet plant has a goal to achieve zero discharge norms with a comprehensive water and waste water management.
The dry circuit consists of crushing and screening and the homogenization yard—everything prior to entering the grinding circuit. The wet circuit includes everything from the four 10-m-diameter ball mills to the pellet plant. A 100-m-diameter thickener decants tailings, while a smaller 40-m thickener dewaters product.
Understanding Pellets and Pellet Plant Operations. Pelletizing is an agglomeration process which converts very fine grained iron ore into balls of a certain diameter range (normally 8mm to 20 mm, also known as pellets. These pellets are suitable for blast furnace and direct reduction processes.

Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.
