“…A number of recent studies indicate that IOTs can be utilized as industrial raw materials to produce green and sustainable industrial products. − However, the extremely high content of MgO and high content of SO 3 in Yeshan IOTs could bring a huge challenge for using Yeshan IOTs as alternative raw meals to produce cement. It has been confirmed that abundant MgO and SO 3 in raw meals have negative effects on the formation of cement clinker. , Additionally, a large quantity of dolomite and serpentine, and relatively abundant clay minerals exist in Yeshan IOTs, which has adverse effects on the performance of concrete if the Yeshan IOTs replace natural fine aggregates in concrete.…”

In this work, twenty-one core samples of tailings wastes were collected from Yeshan iron tailings pond in Jiangsu Province, China. The mineralogical−chemical properties of Yeshan iron ore tailings (IOTs) were investigated to explore potential utilization. Mineralogical investigations and mineral liberation analysis indicated that the iron tailings have complex texture and incomplete mineral liberation, suggesting further grinding can improve higher recovery. Yeshan IOTs accumulated much higher MgO originating from dolomite, therefore, it could be infeasible to utilize a large quantity of Yeshan IOTs as alternative raw meals for cement clinker or replace aggregates in concrete. 2D vertical distribution profiles created with the ordinary kriging method presented heterogeneous distributions of major elements, and the variation trends were inconsistent. The results obtained in this work provide insight for exploiting and reducing Yeshan IOTs.

“…The constant increase in iron-containing waste reserves and the reduction in natural ore reserves indicates the need to process tailings and other mineral wastes. Currently, there are several different ways to utilize tailings, including iron recovery [4][5][6][7], production of building materials [8][9][10] and glass ceramics [11], yellow-red pigment manufacture [12,13], and magnetic nanoparticle production [14][15][16].…”

In this paper, the properties, mineral magnetic modification, and beneficiation of tailings from the central mining and processing plant in Kryvyi Rih, Ukraine, have been studied. Samples were investigated by X-ray diffraction, X-ray fluorescence, microscopy, and magnetization measurements. The beneficiation was conducted using magnetizing roasting with carbon monoxide followed by dry low-intensity magnetic separation. The effects of chemical, mineral, and granulometric composition on the processing of fine tailings of different sizes sampled at different points of the tailings pond were investigated. Additionally, we proposed a new approach for magnetic separation of fine magnetically modified tailings based on the combination of permanent and alternating magnetic fields. Magnetizing roasting resulted in an enhancement in mass magnetization to 11–62 Am2/kg in comparison with initial values of 0.3–1.5 Am2/kg. After magnetic separation, the magnetic concentrates consisted almost completely of magnetite (with the magnetization of 75–88 Am2/kg) and non-magnetic residues contained major quartz. The content of iron in magnetic concentrates reached 68.5–70.2 wt.% and iron recovery 77–96 wt.%, depending on size fraction. We could conclude that the tailings are represented by fine-grained liberated material that can be effectively upgraded using magnetizing roasting and magnetic separation into two valuable products, such as iron concentrate and quartz powder.
