Improving flocculation and dewatering performance

In this paper the bench and fullscale flocculation behavior of iron ore tailings is investigated in order to improve the dewatering performance of tailings thickeners of an iron beneficiation plant In the batch settling tests, the effect of flocculant dosage (5–20 g/t solid), In this plant 700 t/h ore (containing 51% iron) is treated to produce 350–400 t/h concentrate with iron contents of 63% The tailing of the iron ore beneficiation plant (containing 17% iron) at a mass flow rate of 300–350 t/h in slurry form with 5–8% w/v solids% is usually dewatered in two parallel thickeners (D = 55 m, H = 66 m)Improving flocculation and dewatering performance In many mineral processing applications it is necessary to know the isoelectric points of the various minerals in the ore to properly perform flotation and other mineral separations However, current zeta potential analysis technology used to determine the isoelectric point of a particle suspension cannot deliver the isoelectric point of each individual mineral, just an average of the mineral Flocculation and dispersion studies of iron ore using

Flocculation Settling Characteristics of UltraFine Iron

Abstract Because of the uniqueness of geological mineralization, tailings obtained from Chenchao Iron Mine have low SiO 2 content of only 2780% Content of Al 2 O 3 and MgO is 1331% and CaSO 4 is 2209% The fineness modulus of the ores is large enough for convenient mineral separation, thus resulting in 1603% −5 μm particles and 2776% −10 μm particles in the tailings, respectively Selective flocculation technology, a recent development in mineral processing, is ideally suited for separation in subsieve size range The only commercial plant based on this technology is also for iron ore beneficiation Cliff's Tilden plant in Cleveland,Selective flocculation of iron oxidekaolin mixtures using This study aims to beneficiate low grade goethitic iron ore fines using a selective flocculation process Selective flocculation studies were conducted using different polymers such as starch amylopectin (AP), poly acrylic acid (PAA), and a graft copolymer (APgPAA) The obtained results were analyzed; they indicate the enhancement of the iron ore grade from 5849% to 6752% using APgPAA Comparison of selective flocculation of low grade
