Slurry pipeline transportation in Indian iron ore mining industry is not only necessary but also desirable as beneficiation of low grade iron ore is done to convert the fines into slurry and finally pellets which leads to mineral conservation of iron ore resource which is limited and non renewable. The pellets are preferred as feed

Nov 13, 20100183;32;In the year, 2002 Iron Ore Fines was sought for by Buyers abroad to replace Lumps and the GOI had approved. This was a major change in iron ore cargo specs from the earlier Lumps to Ore Fines in Exports. Ore Lumps of larger size does not usually become a slurry if
Table of ContentsDesign Considerations for Selecting a Grinding SystemOpen vs. Closed Circuit Dry GrindingEffect on Pellet QualityOperating Considerations Screening during the production of high grade lump ore for blast furnace burden, particularly from recently developed ore deposits in Australia, South America, and Africa, has resulted in large tonnages of fine iron ore.
Vallourec's beneficiation plant produces concentrated iron ore lumps and fines in Pau Branco mine . Tailings are composed of both fines (gt;45 m) and ultra fines (lt;45 m). Ultra fines are generated from the de sliming cycloning of the magnetic concentration process, and fines are the rejects of this process.

the liquid solid suspension called slurry by using a filter element which separates the unwanted fluid material from the solids from the feed. The paper attempts to establish the way towards analysis of Hyper Baric Filter (HBF) performance at 10m particle size treating iron ore fines (24% to 29%).
Iron Ore Fines The sample of iron ore fine used in this work was supplied by the wash ing plant of the Noamundi area, Bihar, India. The particle size and chemi cal analysis of the supplied sample are given in Table 1. As shown, the passing size for 60% of the particles was about 45 Fm and Ds0 (i.e., 50% passing) was 30 pm.
The study reveals that the blending of fines with coarse iron ore at a controlled particle size distribution supplemented by small dosages of low cost additives may be employed for preparation and transportation of high concentration iron ore slurry with improved pipe economics.

pelletization of iron ore fines and the influence of particle size on the green pellet properties. 2. 2. Materials and Methodology 2.1. Sampling and Characterization Approximately 50 kg of iron ore fines was collected and after sampling was carried out, particle size analysis was done. Iron ore sample belongs to the Gua mines, located
pH in Iron Slurry Industry Steel Product pH . Introduction During mining and processing, generation of fines and slime typically ~ 35 % and 1025% of runof mines is a great concern to environment and loss of iron value. Iron ore fines and slime contain ~ 58 % Fe, high amount of
eficiation of fine iron ore fines was studied in Kelsey Jig. A constant pulp density (25% solids) of the feed slurry was maintained in the study. The feed rate was also kept constant at 60 kg/hr (dry solids basis). Magnetite of size 0.853 + 0.6 mm was used as ragging material to avoid the pegging of internal screen having an opening of 425 m.
m = density of slurry (lb/ft 3, kg/m 3) c w = concentration of solids by weight in the slurry (%) s = density of the solids (lb/ft 3, kg/m 3) l = density of liquid without solids (lb/ft 3, kg/m 3) Slurry concentration by weight can be measured by evaporating a known weight of slurry and measure the weight of dried solids.

to a minus 6' x 6' size. Ore smaller than 1/4quot; is pumped in slurry solution to the wet cobber magnetic separator, which begins the process of separating the iron from the non iron material. The magnetic iron ore is then laundered in two slurry surge tanks while the non magnetics (silica/sand) go to the
Improved dewatering of iron ore fines by the use of surfactants amount of water to make 50% pulp density and mixed thoroughly with a glass rod for about 5 min and then the whole slurry was put on a hand sieve of 0.5 mm aperture size and screened for 1 min (this is the maximum time the fines get over a dewatering screen at any mineral

In the latter, the extraction of minerals from ore requires comminution, i.e., grinding the ore into fine particles to facilitate extraction of the target element(s). Because of this comminution, tailings consist of a slurry of fine particles, ranging from the size of a grain of sand to a few micrometres.
The effect of various dispersion parameters; such as slurry pH, solid concentration, stirring speed and time, and water quality has been extensively studied for stabilization the ultra fine iron ore slurry prior to selective flocculation. The PZC of Dilband iron ore system was found by using the Zetaphormeter III (CAD E400) at pH value of 4.25.
India is the fourth largest producer of iron ores in the world and occupies sixth position in worlds iron ore reserves. About 167 million tons of iron ores constituting lumps, fines and concentrates produced in the were year 2011 2012, showing decrease of about 19% as compared to that in the year 20102011 .
