Sulphur removal of iron ore tailings by flotation Journal

 · Beneficiation of iron ore tailings is a significant issue in the world steel industries from the point of view of both pollution control and secondary resources. This investigation addressed the processing of tailings with high sulphur content from an iron ore concentrator to produce pellet feed fines and to prevent acid mine drainage.

3 Tailings Disposal MethodsXinhai

 · Tailings are the material in the concentrator that have a low content of useful components and cannot be used at present. And the tailings disposal is one of the important links in mineral processing. At present the tailings disposal methods are generally divided into tailing reprocessing tailing dehydration and tailing filling goaf.

Production of a Phosphate Concentrate from the Tailings

Apatite is the main source of phosphorous for the making of chemical fertilizers. While apatite is usually recovered from phosphate orebodies as the primary product of a mining exploitation this paper documents the approach taken to produce a phosphate concentrate as a secondary product from the tailings of a niobium ore concentrator. The conventional desliming/flotation scheme used to

A century of red water mine waste legacy contamination

 · Iron mining in the Mesabi Range began in 1893 and for the next 17 years only high-grade iron ores were mined in the region and no tailings were produced. In 1910 the first shipment of low-grade washable ore arrived at U.S. Steel s Trout Lake concentrator and the first tonnage of tailings were soon dumped into Trout Lake (see Fig. 2).

The water loss in the concentrator (the moisture in the product) accounts for only 0.5 . In iron ore concentrator plants which have higher product mass yield than copper plants the water consumption increases to 15 at the concentrator and decreases to 85 at the tailings dam. In both plants the water consumption in the tailings dam is high.
