Tailings are one of the largest solid wastes in stock at present. In order to improve the comprehensive utilization rate of tailings, especially to solve the problems of finegrained tailings treatment, the concrete composite admixture was prepared by using iron tailings powder and slag powder. In order to study the influence of iron tailings powder on

Iron ore tailings are industrial solid wastes generated from mineral processing. The disposal of iron ore tailings leads to environmental threat and serious security because of their tiny particle size and large storage. In this paper, suspension magnetization roasting and magnetic separation technology were utilized to recover iron
Among the mining industry tailings and byproducts described in the literature acting as polymer additives are: (1) bauxite mining byproducts (Al 2 O 3, red mud) 2, 3, (2) iron 4, (3) tailings
Mine tailings management is a longterm process that starts well before any tailings are produced (Figure 2). It can be difficult to estimate the ‘typical’ cost of building, operating and closing a tailings storage facility as it depends on many factors, but examples suggest upfront capital costs can be around 15 per
Iron ore, one of the most abundant metals on Earth, is the primary raw material used to make steel. Operations. licences and other requirements. Tailings management has been included in the Group risk register since
for high tailings facilities in the deep valleys of the Andes in South America. 2.1 NET PRESENT VALUE ACCOUNTING APPLIED TO TAILINGS MANAGEMENT There is a commonly held perception that transporting tailings as a slurry to a facility is the most economic approach. However, to a large extent this tailings dewatering, density and
Iron tailings can be used as adsorbents to effectively remove graphene oxide (GO) in aqueous solutions. Experimental data show that pH, iron tailing quality, GO concentration and temperature have significant effects on the removal of GO, the adsorption of the tail involves a single layer adsorbed Langmuir model with exothermic reaction, and

5. Tailings management within the circular economy in mining. In this chapter, the possibilities to manage the mine tailings with reduce, reprocessing, upcycle, downcycle and disposal strategies are discussed. In the subchapter 5.2, an inventory of the metal content of mine tailings in Finland is presented. 5.1.
In this study, the kinetics and mechanism of the leaching of iron from copper tailings using sulfuric acid were studied. Under optimal conditions (40 °C, sulfuric acid concentration of 0.53 mol L −1,stirring speed of 400 rpm, solid/liquid ratio of 1 : 10 and leaching time of 120 min), 66.45% of Fe, along with 65.32% of Zn and 59.95% of Cu

This paper reports a study on the reconstruction of broken SiOSi bonds in iron ore tailings (IOTs) in concrete. Limestone and IOTs were used to investigate the influence of different types of coarse aggregates on the compressive strengths of concrete samples. The differences in interfacial transition zones (ITZs) between aggregate and
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 aluminasilicate raw material for the production of Portland cement clinker. For this purpose, two kinds of
