The magnetic flocculation behaviour of two kinds of iron oxide mineral (hematite1 and hematite2) was studied by using a newexperimental device, in which a stirred container was set in an applied magnetic field. Magnetic flocculation of both minerals occurred in very low applied magnetic fields. Hematite1is astrongly paramagneticmineral, theflocculationrecoveryimproved
iron ore material was investigated by determining the effects of changing the operating parameters of pulp solids, magnetic field intensity and the pulsation frequency. This was followed by a 33 full factorial design which consisted of twenty seven (27) test matrix, with
The paper focuses on a kaolin ore which containing harmful composition of Fe2O3, TiO2 and SO3 and uses united process of gravitystrong magnetic separation and gravityselective flocculationstrong magnetic technology to remove the harmful composition. Finally, the united process of gravityselective flocculationstrong magnetic separation process is better.
FIGURE 3 Hydrophobic flocculation of bituminous coal fines being fresh (q=º) and oxidized at 170 oC (q=25º) as a functions of suspension pH FIGURE 4 Effect of sodium oleate addition on the beneficiation of Donganshan hematite ore (81% minus 10 mm in size) using hydrophobic flocculation magnetic .
Flotation Cells For Iron Ore Benefication 201982 · Does anybody have experience of working with WEMCO flotation cells to remove sulfur in iron ore reverse flotation circuits? Could it be a good choice for flotation of coarse and dense iron ore particles without any settlement?
Development and Utilization of the MicroFine Weakly Magnetic Iron Ore Efficiently Utilizing a Low Grade and Complex Copper Ore by Flotation
Abstract. The flocculation and filtration characteristics of typical Indian iron ore fines have been studied using starch as flocculant in the presence of an inorganic electrolyte, namely calcium chloride. The effect of various parameters such as pH, starch and calcium chloride concentrations and pulp density on the settling and filtration rates,...
Iron ore sintering consists of heating a layer of fines until partial melting occurs and individual ore particles fuse together. For this purpose, a travelinggrate machine is used, and the burning of fine coke (known as coke breeze ) within the ore generates the necessary heat.

Acrylic acid polymers of specified composition and solution viscosity are selective flocculants for iron values derived from hematitic ores in the presence of nonferrous minerals. USA Process for selective flocculation of hematitic iron ores in the presence of nonferrous minerals Google Patents
The sample contained pct iron and represented approximately 2 billion tons of crude material. Selective flocculation and flotation were evaluated in a pilot plant with a feed rate of 900 lb/hr. Concentrates averaging 61. 7 pct iron and pct silica were obtained, with an accompanying iron recovery of pct.
A large number of coagulants and flocculants are commercially available. A few examples of coagulants include iron chloride, iron chloride sulphate, polyaluminium chloride, polyamides and polytannines. Flocculants can be cationic, anionic and nonionic. Acid and base may need to be added to reach the required pH range for the product.
2. 49 Sintering of iron ore fines from some deposits in Bihar Orissa sector on batch and pilot plant scale. Val. Mineral Hematite Gangue Quartz Shale Satisfactory sinter obtained by using 7% coke breeze, 5% moisture and 30% iron fines. Product A Fe Al 2O 3 SiO 2 Product B 3. 370 Beneficiation of a sample of Iron ore
tem is not the magnetic flocculation of very fine particles but the recovery of these flocs against the inertial forces developed within the separators. High intensity and high gradient magnetic separators are now increasingly in use to separate feebly magnetic minerals from fines and slimes. Use of ceramic
