How a Thickener Works Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flatbottomed tanks into which the pulp was fed until the tank was full.
Thus, for every four tons of ore at 35% iron, 1.8 tons of concentrate at 65% iron would be produced. The 2.2 remaining tons at 10% iron would be discharged to the tailings deposit. The concentrated ore is palletized in a heat hardening operation with the aid of a suitable binding material such as bentonite.

Iron Ore Tailings Recycling Machine Of Iron Ore Tailings IRON ORE TAILINGS BENEFICIATION. Iron ore tailings recovery is mainly used for iron ore in the tailings recovery process, not the loss of iron ore, so that resources Paste Thickening Iron Ore Tailings. tailings for water recovery and an alternative to conventional dams and ponds.
Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue, slickens, or terracone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining
A pilot scale paste thickener thickened iron ore tailings to underflow solids ranging from 55 to 80 wt%. (ANN) model (443) was used to predict the separation performance of the process in. Dry Tailings Plant Outotec. Outotec Dry Tailings Plant product consist of thickening, filtering and dry material handling processes.
Mexican iron ore mine – surface paste tailings system development: a case study L Botham and J Johnson 46 Paste 2018, Perth, Australia Figure 3 Benchscale rheology test result (HaakeTM ViscotesterTM 550) The recommended paste type thickener for this appliion is the WesTech HiDenistyTM and the general dimensions of 15 m diameter, an 8 m vertical sidewall and a 14° floor
In this case, two different scenarios of an openpit iron ore mine will be assessed. Stage 1 corresponds to the traditional tailings dumps and stage 2 with tailings thickening up to 70% before their final disposal. Even though one of the advantages of this technique is the
Iron ore tailings dry stacking in Pau Branco mine, Using the thickened sample from the previous test, laboratory leaf filtering tests [7] were performed. The equipment consists of two plates, with an area of 300mm2, double faced, chamber thickness of 35mm, and solids concentration
