Minerals are mostly subjected to ore
processing or ore enrichment processes to make them usable and salable raw
materials. Firstly, ore is minimized by crushing-grinding process, and after
the use of water and chemical additives according to the characteristics of the
mineral, beneficial mineral is taken, while unwanted minerals are stored in
waste (tailings) pools. In a study, approximately 26 million tons of mineral
waste are generated annually from the mineral processing facilities in Turkey.
Construction of waste pools, stability of waste sludge and ensuring the safety
of dams is a burdensome situation that miners face. In ore processes, an
average of 3 tons of water is used to enrich 1 ton of ore, and most of the
waste water cannot be removed with traditional methods and causes various
economic and environmental problems. In this paper, the dewatering of an iron
ore process waste by electro-osmosis method was investigated in a laboratory
environment. Parameters such as amount of water removed, density, void ratio,
water content and power spent in dewatering experiments were determined and the
relationships between them were discussed in the graphics. Among these
parameters, the water content of the waste material, which was 84,8% at the
beginning, was reduced to 18,4% by the electro-osmosis method.
