Any non magnetic material which has been released by the rod mill is separated and sent to the tailings thickener. Magnetite iron ore particles are separated by the magnetite separator from the gangue minerals in the cobber magnetic separators. This material flows to the ball mill for further size reduction.
Alibaba offers 2,112 ore thickeners products. A wide variety of ore thickeners options are available to you, such as local service location, usage, and applicable industries.
Figure 2. Water balance of a high density thickener in an iron ore concentrator plant. The most common problems in thickener operations include the presence of suspended solids in the recovered water and the density or percentage of solids of the thickener discharge outside the set targets.
thickeners and at the two 18 m paste thickeners. The net raw water usage has been minimized, and water losses on the are at levels of between 0.43 to 0.69 m3/t deposited.

They are magnetite , hematite , goethite , siderite , and pyrite . Mining of iron ores requires drilling, blasting, crushing, screening, and blending of the ores. Crushing and screening are an integral part of ore producing facilities.
The standard construction of Dorr thickener mechanisms is of iron and steel. The tanks are usually made of steel or wood for medium sized machines, but in the larger sizes they are often constructed of concrete or earth or a combination of these materials.
The following examples illustrate the effect of the system consideration on selection of the paste thickener. Iron Ore Tailings. The integration process for the paste system at a South African iron ore plant identified the following high priority design parameters : A greenfield plant; tailings disposal site must be ...
