Beneficiation of Beni-Khaled Limestone Ore for Beneficial Industrial Uses

Effective Beneficiation of Low Grade Iron Ore Through Jigging Operation

The effectiveness of jigging operation for the beneficiation of low-grade iron ore deposits of Orissa, India has been investigated. Iron ore sample obtained from Barbil region of Orissa containing very high amount of silica and alumina was crushed using the laboratory jaw crusher and roll crusher to prepare different particle sizes. The sink and float tests were carried out to evaluate the poss...

Effectiveness of Gravity Separation Methods for the Beneficiation of Baban Tsauni (Nigeria) Lead-Gold Ore

The response of Baban Tsauni (Nigeria) lead-gold ore to gravity separation methods was investigated in this research work. Value addition to run-off mines is always necessary in order to reduce downstream metal extraction costs. Gravity separation methods (the focus of this work) are the cheapest beneficiation methods. This study applied three gravity separation methods: jigging, multi-gravity ...

Microbial Treatment of Lateritic Ni-ore for Iron Beneficiation and Their Characterization

Th is study aims at studying effect of anaerobic dissimilatory iron (III) reducing bacterial consortium on different phases of iron present in lateritic n ickel ore. Such conversion in lateritic nickel ore are helpful in better recovery of sorbed metal values like Ni and Co by subsequent bioleaching or acid leaching. Here properties of thermally and microbially reduced lateritic nickel ore are ...

Beneficiation of a High Dolomitic Phosphate Ore: a Bench Scale Optimization Study

A three stage flotation scheme was employed to beneficiate a low grade. high dolomitic phosphate ore from Florida. The reagent scheme used. developed on the basis of our previous fundamental studies. consisted of oleic acid added as collector. mineral oil and ethoxylated sulfonate as co-collectors and 1. hydroxy ethylidene 1.1diphosphonic acid (Dequest 2010) as francolite depressant. The three ...
