Adsorption of polyacrylamide flocculants onto the iron ore tailings is established Effects of pH and flocculant doses on zeta potential of the tailings were studied Adsorption data was validated with Langmuir and Freundlich isotherm models Flocculation and settling studies were carried out to optimize dewatering conditions The investigation outcomes are directly
A sample of a siliceous Cu Ni PGM ore was received from a South African PGM ore mine site The ore was crushed to a size of −1 mm before being blended riffled and split using a rotary splitter into 1 kg samples The 1 kg ore samples were stored in airtight bags in a sealed drum at room temperature
A current trend amongst producers is the increase in dewatering of iron ore fines mm due to an increase in wet beneficiation processes used to upgrade lower quality ore deposits increased water content in orebodies located below the water table and increasing focus on transportable moisture limits tml vacuum filtration is commonly used for dewatering of iron ore fines and as
Inorganic flocculants These include aluminum based compounds such as aluminum sulfate alum and polyaluminum chloride PAC as well as iron based compounds such as ferric chloride and ferric sulfate Inorganic flocculants are widely used in water treatment due to their effectiveness and relatively low cost
This article discusses the effect of physical and chemical modifications of starches on the anionic and cationic flotation of silica from oxidized iron ores and magnetite taconite concentrates and the results of the interaction of starch pH and calcium ions on the flocculation clarification and filtration of iron ore slimes and magnetite taconite tailings Starches particularly when
