The role of chemical reagents to reduce moisture in iron ore fines is explored in the present work which includes ionic and non-ionic surfactants. The washing of iron ore in mineral processing plants result in moisture of about 11–14% in the fines and about 4% in the sized ore.
Platts Iron Ore Index, or IODEX (IODBZ00), is a benchmark assessment of the spot price of physical iron ore. The assessment is based on a standard specification of iron ore fines with 62% iron, 2.25% alumina, 4% silica and 0.09% phosphorus, among other gangue elements.
Forty grams of LIMS iron ore concentrate particles were added into 200 mL CTAB solutions of 120 mg/L (equivalent to 100 g/t) prepared with deionized water and stirred for 5 min, then, it was poured into filter chamber and filtered. Five pressure levels were performed ranging from 2 …
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
<9% cake moisture for iron ore concentrate is possible without addition of reagents, but depends on several factors: type of filtration equipment (vacuum or pressure filter), PSD of feed slurry, % feed solids, and type of iron ore, among other factors.
