Nov 29, 2011 The sample of iron ore that was tested responded well to vacuum filtration provided that anionic flocculants were used as a filter aid. In the presence of these polymers, cake formation times were very short (mainly below 10 seconds) and the moisture levels of 18 mm thick filter cakes were reduced to 10–11 wt after dewatering times of only.
Vacuum was applied to the filtrate flask by means of a vacuum pump, and its level measured by a vacuum gage and regulated to 60 KPa by using a control valve. Each test was performed by reconstituting the iron ore concentrate slurry with water to give.
The EIMCO-K.C.P. Horizontal Vacuum Belt Filter has most of the operating capability of a bottom pickup vacuum filter additionally, it has the operating flexibility to meet particular processing requirements some unique and exclusive capabilities – Simplicity of operation, and fluctuations, the ability to handle feed with low and high solids concentrations, and highly effective cake.
DELKOR Horizontal Vacuum Belt Filters. The horizontal belt filter is an efficient and reliable liquid solid separation machine suitable for dewatering a wide range of commodities such as iron ore, mineral sands, lead zinc concentrates, fine coal flotation concentrates, phosphoric acid filtration and others.

BACKGROUND. This invention relates to dewatering iron ore concentrates for use in iron and steel making. U.S. Pat. No. 3,292,780 teaches an iron benefication process in which a dispersion of finely ground iron ore of a primarily nonmagnetic type is subjected to preferential flocculation of iron oxides to remove slimed silica prior to treatment of the deslimed residue by conventional flotation.

Commercially available flocculants . The efficiency of the synthesized graft polymer has been tested in relation to the flocculation of iron ore slimes followed by filtration. Variables which affect the kinetics such as pH value of suspension, solid concentration of pulp, dose of flocculant [10-11] have been studied in the present work.

Iron ore and iron ore pellets are important sources of iron for manufacturing steel.
Jun 09, 2013 Dewatering of iron ore slurry by a ceramic vacuum disc filter – Aidic. d50 = μm and d90 = μm). The dry iron ore was mixed with tap water to produce the slurries with the desired solid concentrations for the filtration tests. detailed.
As the demand for iron ore rises, so does the need for higher capacities. Maybe it’s processing huge volumes of low-grade ore with minimal residual moisture. Or doubling your throughput with a high-capacity filter press. In either case, we have an innovative solution to make it both possible and profitable. Filter press Horizontal vacuum belt.

Jan 02, 2012 The upgrading of iron ore is a high-tonnage industry where cost efficiency plays an important role. Reducing costs of the filtration section can be done by the introduction of technology which results in decreased specific energy consumption. The use of the ceramic filter medium can offer this advantage. In addition, the filter medium can withstand chemical regeneration beyond that which.
A single operation of pig iron production requires about 150 tons of water and 3.5 tons of air to produce one ton of iron. Likewise, every tonne of steel produced gives about 20 tonnes of liquid wastes, 5 tonnes of waste gases and 1 ton of solid wastes.
We claim 1. A process for improving the dewatering of an aqueous slurry of an ore concentrate solids which will subsequently undergo filtration to provide a filter cake of the ore solids having a low moisture content and better handling and processing characteristics, which process comprises adding to said slurry prior to filtration an effective amount for the purpose of a dewatering aid.
Jul 24, 2017 Vacuum filtration is commonly used for dewatering of iron ore fines, and as with all filtration processes performance decreases with particle size. Significant improvements are possible with the use of filter aids, usually anionic surfactants and flocculants.
Jan 01, 2016 The washing of the iron ore fines results in a moisture of about 11–14 in the fines and about 4 in the sized ore. The moisture content goes up to 16–18 in the fines during the monsoon season. Indian iron ore contains hematite and goethite as the major iron bearing minerals. Alumino-silicates are the gangue minerals , , , ,.
