The iron ore mineral slurry was sourced from a mine in Pilbara region of Western Australia. The particle size distribution of this slurry measured by a Mastersizer Microplus is as follow: D 10 = 0.28 μm, D 50 = 4.01 μm, D 90 = 76.39 μm, volume means size D[4,3] = 23.82 μm and surface area mean size D[3,2] = 0.82 μm.
The optimization of apparent viscosity for rheological characteristics of iron ore-water slurry have been studied by considering the effects of operating parameters in the range such as solid ... Effects of slurry rheology on industrial grinding performance. Int. J. Miner. Process, 65 (3/4) (2002), pp. 125-140. View PDF View article View in ...
Slurry in a sand magazine. Photo: Pontus Westrin, SGU. Enrichment process and tailings. Valuable metals or elements are enriched and separated from the mined ore via ore processing, which also generate a type of waste in the form of tailings. Tailings are often deposited in tailings storage facilities aiming to protect the environment.
The present study demonstrates a comprehensive characterisation of an Indian iron ore sample to investigate the effect of blending coarse particles with fine particulate slurry on the rheology, slurryability, and stability of iron ore suspension. Various bench-scale tests are carried out to determine iron ore samples' physico-chemical, …
Kolkata Ball Mill Grinding Media Calculation - Lowering Respirable Dust at an Iron Ore Concentrator Plant … About Us.

The Hira Process is the Ore ground to the required fineness through wet grinding process mainly by Ball Mills and the slurry is dewatered by pressure filtration to produce the Iron Ore Concentrate. The Iron Ore Concentrate produced is mixed with additives viz., Lime, Dolomite, Coke and Bentonite in suitable proportions to meet the required ...
A rigorous literature review has been carried out on rheological behavior of hard and soft particle slurries. The rheological characteristics of unimodal and bimodal suspension are presented. From experimentation, it was observed that mineral viscosity increases with solid concentration, while decreases with temperature. Addition of 30% …
It was seen that microwave-treated ore have better rheological properties as compared to untreated ore. This type of slurry is shear thinning and easy to transport as it exhibited pseudo-plastic behavior. The result showed that microwave-treated iron ore have a density lower than that of untreated ore after grinding.
Slurry rheology affects both the breakage behaviour and the mass transport mechanism in a grinding mill, and hence, influences the milling energy efficiency. The present authors are aware of over 40 references dealing with rheological effects on particle breakage, mass transport, mill power draw, and the use of grinding aids.
