Originally known as Humphreys spiral (after the inventor) a wide range of devices are now available. A spiral concentrator consists of a helical conduit of semi-circular cross-section. Feed pulp of between 15 and 45 percent solids in the size range 3 mm to 75 μm is introduced at the top of the spiral
quoted priceJun 18, 2015 · Typical spiral concentrators will use a slurry from about 20%-40% solids by weight, with a particle size somewhere between 1.5-.075 mm (17-340 mesh), though somewhat larger particle sizes are …
Get DetailsMultotec-designed spiral concentrators are used across the world in coal, gold, iron ore, mineral sands, platinum and chrome processing plants and other minerals.. As a turnkey supplier of gravity concentration equipment across the world, Multotec can deliver end-to-end spiral solutions, from process audits and test work, to complete spiral concentration plants optimised for your process
Get DetailsThe Spiral separator/ spiral chute is the earliest mining machine. It has been used to classify the granularity 0.3-0.02 millimeters fine grain like iron, tin, tungsten, tantalum-niobium, gold ore, coal mine, monazite, rutile, zircon, and other metals. The non-metallic minerals which have a big enough specific gravity difference
Get DetailsThe 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 processing plant
Get DetailsOct 15, 2014 · The measurements used for the analysis were the ore size distributions ranging from 14 to 200 mesh (1.20–0.075 mm), the chemical assays (Fe, SiO 2, Al 2 O 3, CaO, MgO, TiO 2, Na 2 O, K 2 O and Fe 3 O 4) of the ore and of the ore within the size intervals of the spiral feed and product streams
Get DetailsAccording to the results, when the feed to the spiral has a larger size distribution, the enrichment ratio of the feed is 1.32 and, with the smaller feed size, this value has increased to 1.99
Get DetailsJun 10, 2014 · This paper uses the mineral size recovery curves to investigate, using a 2 3 factorial design, the effect of the slurry solid concentration, slurry feed rate and wash water addition on a WW-6 spiral processing an iron ore. The first section describes the set-up used for the tests and the test results are analyzed in the second section
