Chromite Sand Testing - Minerals Tech

melting silicates that are entrained in the chromite sand during processing and can contribute to certain types of casting defects. • This test has traditionally been conducted with a Jackson turbidity tube which is a glass cylinder with a candle placed under it. A sample of chromite was shaken in a beaker with water and the turbid liquid is

BENEFICIATION OF CHRONIITES

These ores contain high silica content than required thereby lowering the Cr„O content of the ore. As the chromite mineral is having higher specific gravity than any of the associated silicate or other gangue minerals present in the ore, they are separated by gravity methods like jigging, tabling etc. depending upon their liberation size.

Flotation of Chromite Ore

Flotation of Chromite Gravity Concentrate. The amine flotation method was applied to chromite gravity concentrates prepared from Benbow-2 ore by a combined Humphrey's spiral and table separation technique. The purpose of re-treating the gravity concentrate was to prepare a low-silica feed material for refractory testing.

DETERMINATION OF FEO IN CHROMITE ORE – MSK

The chromite ore is normally having a composition of FeCr2O4 which may be written as FeO.Cr2O3. In some ore Fe is partially replaced by Mg as (Fe, Mg) Cr2O4. The ore may have Fe in other form besides being present in the spinel. An accurate determination of FeO content is extremely important in chromite ores and refractories made with them.

The chromite ore used in this study was from the LG-6 layer of the Bushveld Complex. The ore was washed and tabled to separate any gangue material. The chemical composition of the chromite after washing and tabling is shown in Table 1. The particle size ranges of the chromite used in experiments were 75–90 μm, 106–125 μm, and 150–212 μm.

Chromite: from the mineral to the commodity

The most commonly used beneficiation methods for chromite ores are the gravity methods, such as the shaking table, jig, spiral and Reichert cone methods. The present work deals with the geologic studies that, coming after prospection, lead to the evaluation of the chromite ore quality and to planning and/or improvement of beneficiation plants.
