I m currently working in a project in which I have to convert the iron oxides present in iron ore slime into ferric nitrate Iron ore slime is which has the particle size of below $\pu{015 mm}$ is being discarded as waste during the mining and processing stages iron ore and it will be stored at the tailing damthe future But due to huge cost of land and safety of the dam it is worth designing an appropriate tailing pond size to a minimum level The purpose of iron ore beneficiation and the cause of surface water pollution and ground water contamination are described Physico chemical characteristics of the tailings of an iron ore beneficiation

Iron ore washing equipment Commonly used equipment in iron ore washing plants includes hydraulic washing screens cylindrical washing machines trough washing machines Linear vibrating screen and spiral classifier The chute can also be used for washing The hydraulic washing screen is a washing method which uses a water gun to rinse on a fixed strip screen and is used for washing difficult tailings Iron ore tailings containing around 48 60 Fe are generated from the iron ore washing plants and are disposed into tailing ponds without any further utility These tailings in the form of slimes are not suitable in iron and steel making due to the presence of higher amount of gangue constituents

Tailing ponds are areas of refused mining tailings where the waterborne refuse material is pumped into a pond to allow the sedimentation meaning separation of solids from the water The pond is generally impounded with a dam and known as tailings impoundments or tailings damsAug 03 32 Mine tailings disposal and its impact on water usage is an important concern for any mining company The challenge today whether extracting aluminum zinc gold or iron ore is how to dispose of tailings material such that it is contained and stable while maximizing water reuse and minimizing surface footprint
