The only viable option currently is to dispose these slimes in tailing ponds for water recovery and future use. Due to increasing demand for steel and rapid consumption of high ...
Jan 01, 2020 The hematite iron ore fines contain reasonable amount of clay minerals, which gives negative affect in wet process for preparation of pellet feed material. It has swelling properties, which causes increasing the viscosity of slurry, and it disturbs the rheology of the slurry.
Aug 31, 2020 Spectroscopic analysis revealed that iron ore samples obtained from the Barbil region of Odisha contain a high amount of silica and alumina in the form of clay minerals e.g., kaolinite contributed as a loss on ignition LOI in the iron-making process. Iron ore fines of below 10 mm size were subjected to a laboratory-scale screw scrubber, and ...
This disclosure relates to a water-less extraction process to collect clay, silica and iron ore from tailings taken from tailings dams and deposits by drying, dry sifting, density separation, mechanical friction separation, air classification separation, milling and magnetic separation. This is achieved by using pieces of equipment arranged in sequential order, as follows a horizontal rotary ...
The present invention is related to a high aspect ratio column thickener and a process thereof useful for dewatering of iron ore tailings. The column thickener has been developed with multiple feed inlet points and an auxiliary inlet point for water to clear the jam of high concentration slurry, if required. The column also consists of a conical portion at the bottom.

Dec 05, 2017 Bentonite Slurry in civil engineering. Bentonite slurry is a combination of sodium bentonite and slurry. A slurry is a thin sloppy mud or cement or, in extended use, any fluid mixture of a pulverized solid with water, often used as a convenient way of handling solids in bulk. This combination is frequently utilized to form a solid protective barrier in the ground.
The bottom of the pit is covered in clay so that no soil gets into the furnace with the iron ore. In the pit we make a big fire and put the pieces of iron ore into it, then let the fire burn for about ten hours. During this process the water content of the iron ore is released, and
Once the feed materials and the flocculant solution were prepared, the hematite iron ore and kaolinite was mixed in a mixture in desired ratio to prepare the synthetic feed to the selective flocculation process. The synthetic iron ore feed was taken in a graduated cylinder and tap water was added to make desired solid concentration of slurry.
