Dense medium separation is well established in the diamond, coal and iron ore industries but is gaining popularity as a pre-concentration step in other industries. The maintenance issues are addressed that will affect the efficiency of the operation. KEYWORDS Dense medium, cyclone, ferrosilicon 2.
Dense medium separation (DMS) is a robust process that can be conducted at particle sizes as coarse as 300 mm and as fine as 500 µm with high separation efficiency, depending on liberation characteristics of the value minerals. The DMS process involves three steps: feed preparation, dense medium separation, and ferrous-based media recovery.
iron ore concentrate (underflow) was effectively separated from the tailings (overflow), ... Should there be more magnetite of specific gravity 4.6, the efficiency of separation decreases. This will eventually lead to a greater percentage of the Fe3O4 going to the tailings

process of mineral separation. Though ore is mined with the highest efficiency of the technology, the excavated ore gets partly contaminated by the surrounding host rock (overburden) and the geological material closely associated with the ore during mining. Both the materials are undesirable and hence form the gangue.
The former mainly selects magnetite ore, and the latter is mainly used for sorting hematite, mixed iron ore and weak magnetic ore. 6.2 Magnetic separation – cation reverse flotation process The grade of iron concentrate increased from 65.55% to 38.89%, the silica content decreased from 8.31% to 3.90%, and the iron recovery rate was over 98.5%.
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.
Beneficiation of Iron Ores. 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 ...
