New heavy mineral spiral for recovery of ultrafine chromite. Spiral concentrators are gravity separation units which are cost and energy efficient. They are widely used to treat various minerals such as coal, iron ore and chromite ore. Separation is based on the difference in the specific gravity of the compounds in the mineral ore

Keywords: Ultra-fine chromite tailings, Magnetic separation, Characterization, Chromite 1. Introduction Chromite recoveries is a major concern particularly in processing of finely disseminated ores due to its inherent complexities. The gravity separation process is the main beneficiation process used to recover chromite mineral. However
gradient magnetic separation. Turkish chromite concentrators consist of gravity separation (shaking tables and spirals) for coarse chromite fractions and a combination of gravity separation and flotation for fines. In India, at both the Sukinda and Boula-Nausahi sectors, chrome ore is
For good separation, the density difference between the heavy minerals and the light minerals in the feedstock should be at least 1 g/cm 3; and because the separation is dependent upon size and density, spiral separators are most effective at purifying ore if its particles are of uniform size and shape. A spiral separator may process a couple
In this study, beneficiation of the spiral chromite tailings taken from South Africa, which contains 22.5% Cr2O3, were investigated by using combination of gravity units. ... Gravity separation
The spiral separators are designed for classifying the granularity 0.3-0.02 millimeters fine grain like iron, hematite, ilmenite, chromite, brasses, tin, tungsten, tantalum-niobium, gold ore, coal mine, monazite, rutile, zircon, and other Non-ferrous metal, rare metal, and non-metallic minerals with different specific gravity in the mineral
The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium-to-iron ratio
Jul 20, 2017 The average grade of the metallurgical chromite ore was 43.4 pct Cr2O3, with 52 pct of the ore having a chromium-to-iron ratio of 3:1 or over, 17.6 pct having a ratio between 2:1 and 3:1, and 30.4 pct having a ratio less than 2:1. Chemical-grade chromite ore generally ranged from 40 to 46 pct Cr2O3 with a chromium-to-iron ratio of 1.5:1 to 2:1

Mar 26, 2016 The Humphreys Spiral has been successfully applied to recovery of chromite from chrome sands, rutile, ilmenite, and zircon from sand deposits, tantalum minerals and lepidolite from their ores, gravity concentration of base metal ores and in the cleaning of fine coal. How it works: Pulp is introduced at the top of the spiral and flows downward
Oct 27, 2020 Separation process of chromite by spiral, like other minerals, is influenced by the feed characteristics, including particles size and density, as well as the operating parameters of feed flow rate, pulp density, and position of the splitters . Successful separation using spirals depends on the correct selection of these parameters . The position of the splitters, which are located at the end of the spiral channel in order to separate
15.5.3 Spiral Concentrator The spiral concentrator first appeared as a production unit in 1943 in the form of the Humphrey Spiral, for the separation of chrome-bearing sands in Oregon. By the 1950’s, spirals were the standard primary wet gravity separation unit in the Australian mineral sands industry
