Research on mineral processing for high silica low grade ...

In order to develop and utilise cheap iron ores with low quality for cost reduction, a hematite ore from Xinjiang province was investigated to determine the iron increase and silicon reduction using ore dressing process experiments. Results showed that iron concentrate with 61%Fe and iron recovery of 66% were achieved through the process flowsheet of grinding, high intensity magnetic separation, regrinding of coarse concentrate, clean concentration by high

The processing of high silica bauxites — Review of ...

01/08/2009  The high silica bauxite is digested under conditions of low temperature (80–105 °C i.e. atmospheric digestion) and solid–liquid separated under conditions to maximise the amount of undigested reactive silica in the residue. The liquor from the atmospheric digestion is then used to digest further low silica bauxite in a conventional digestion. The second digestion therefore increases the alumina

Improvement of Low-Grade Silica Sand Deposits In Jeddah Area

Improvement of Low-Grade Silica Sand Deposits 119 Scrubbing the untreated feed sample (without flotation) upgrades silica content to 93.4% which is comparable with the flotation concentrate. Washing alone, without flotation, does increase the silica content to slightly less than flotation and scrubbing, but the iron content remains high. However, the fine

Metallurgical Grade Silicon. Silica is the dioxide form of silicon (SiO 2) and occurs naturally in the form of quartz. While beach sand is also largely quartz, the most common raw material for electronic grade is high purity quartz rock. Ideally the silica has low concentrations of iron, aluminum and other metals. The silica is reduced (oxygen removed) through a reaction with carbon in the ...

Production of High Grade Iron Ore Concentrates Using Flota

processing routes. The requirement for higher quality pellets demands that the silica content be lowered to levels ranging from 2.0% SiO 2 to below 1.0% SiO 2. Reverse flotation (silica is floated away from the iron concentrate) has proven to be an economical and effective me thod for reducing the concentrate silica content to very low levels. Laboratory and commercial test -work has demonstrated some

Epithermal Gold for Explorationists AIG Journal

The good metallurgy of coarse grained quartz-sulphide ores has lead to easy gold extraction by heap leaching of weathered very low grade material (e.g., San Cristobal, La Arena, Vueltas del Rio). However, in tropical settings of deep weathering supergene enrichment may result in the chemical and mechanical concentration of anomalous gold near surface or close to the base of oxidation, such that surface gold grades
