optimal consume of naoh in starches gelatinization for

The major source of starch used for iron ore is corn starch, which needs to be gelatinized with sodium hydroxide (NaOH) prior to use. This stage has a direct impact on industrials costs, once the lowest consumption of NaOH in gelatinization provides better control of the pH in the froth flotation and reduces the amount of electrolytes present in the pulp

synthetic flocculants for iron ore beneficiation

Synthetic Flocculants For Iron Ore Beneficiation. Selective Flocculation Of Iron Oxide From Its Synthetic . Polyaarylic acid paa and starch represent two of the most widely used commercial flocculants in the mineral processing industry.Both are known to behave as selective flocculants in the beneficiation of iron ore slimes.This paper compares these two types of flocculants in achieving

development of a highly efficient selective flocculant

It has been found that the developed material has promising selectivity toward the hematite particles and also demonstrates faster settling of hematite particles. The developed material is found to be superior in all aspects than that of conventional selective flocculant used for iron ore beneficiation (i.e., starch)

beneficiation of iron ore - mineral processing & metallurgy

Mar 19, 2017 · Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice. This also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. All such plants are large tonnage operations treating up to 50,000 tons per day and ultimately requiring grinding as fine as minus 500-mesh for liberation of the iron …
