In commercial concentration processes some ore mineral is necessarily lost in the tailing or reject, the percentage so lost ranging between wide limits, depending on the character of the ore and the refinements of the ore-dressing methods employed.
The cement industry has for some time been seeking alternative raw material for the Portland cement clinker production. The aim of this research was to investigate the possibility of utilizing iron ore tailings (IOT) to replace clay as alumina-silicate raw material for the production of Portland cement clinker. For this purpose, two kinds of clinkers were prepared: one was prepared by IOT; the ...

Hematite(week magnetic ore) is refractory minerals. Before, the flotation and roasting-magnetic separating process are mainly used. For the past few years, due to the application of strong magnetic separator, undersize sieve etc new equipment and gravity separation equipment, reverse flotation process, hematite (week magnetic ore) dressing have got remarkable effect.

The tailings dams were built by Samarco to accommodate the waste resulting from the extraction of iron ore taken from extensive Germano mine, located in the Mariana district of Santa Rita Durão. The Fundão dam was constructed in the hills near the village and subdistrict of Bento Rodrigues, located 14 kilometers (8.7 mi) north of Mariana city.

Iron ore tailings (IOTs) are a form of solid waste produced during the beneficiation process of iron ore concentrate. In this paper, iron recovery from IOTs was studied at different points during a process involving pre-concentration followed by direct reduction and magnetic separation. Then, slag-tailing concrete composite admixtures were prepared from high-silica residues.
Abstract: Iron ore tailings as a kind of waste products after ore dressing is one of the major industrial solid wastes. Iron ore tailings not only cover huge land and pollute environment, but also give rise to security risks. The comprehensive utilization of iron ore tailings need to be studied systematically.

For example, a tailings stream in an iron ore application could be thickened to 45–50% solids Newtonian slurry in conventional or high-rate thickeners. Conversely, the same tailings stream could be thickened to 65–70% solids non-Newtonian suspension using a paste thickener. Water Recovery
The objective of this study is to evaluate the modified performance of concrete with mixing of iron ore tailings in order to solve the shortage of natural sand and make full use of industrial waste. Firstly, the raw materials of mixing were analyzed, and the test ratio was determined. Secondly, the workability and mechanical property of concrete specimens with different amounts of iron ore ...
At present, iron ore resources are decreasing day by day, which is characterized by more lean ore than rich ore, more associated ore and complex ore composition.
