The experimental results of the present study indicate that a cement-fly ash composite binder can be very effective in stabilizing iron ore mine tailings. 2. Test specimen with Mix ID TM/5/0/0, TM/5/5/0, TM/10/10/0 produced adequate compressive strength values >345 kPa, but failed in achieving the required hydraulic conductivity < 1.0x10-5 cm/sec.

Abstract The mining industry has seen several significant dam failures in recent years. Dam failures are associated with errors in design, implementation, operation, and monitoring (Azam, 2014, [2]). Dewatered stockpiling (dry stacking) is a safer alternative to tailings dams (Rico et al., 2008, [3]) for tailings disposal; however, this method has not yet been used in iron ore mines in Brazil ...

The proven design and performance of Alfa Laval solid bowl centrifuges are based on decades of research and development in challenging solid-liquid separation applications. In Australia, the technology is used for coal, copper, iron ore, gold, nickel and uranium tailings.

The filtration section of the old gold plants dropped a filter cake (10 - 15% moisture) into what was known as a "puddler" ahead of pumping to a storage tank for tailings disposal. These operations had the advantage of wash water going onto the belt thereby adding a bit more moisture. The water addition was via level control in the puddler.

The concentration of iron ore by flotation is a technique consolidated worldwide for mineral particles ranging from 10 to 250 μm [1]. In Brazil, all the main pellet-feed producers use re- verse flotation, being the tailing made up mostly of quartz and a concentrate constituted of iron oxides and iron hy- droxides.

Tailings and Mine Waste 2014 October 3, 2014. ABSTRACT. Globally, mine operators are becoming increasingly aware of water availability costs and constraints. This is leading to a trend of de-watering tailings disposal particularly where fresh water is required for processing. The Karara Mining Limited operation located in the Mid-west of ...

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 …

1. Introduction. Nowadays, the most challenging issue in the iron ore mining industry is tailings management and water recovery. Due to a number of problems such as water scarcity for processing, space limitation for tailings disposal and the environment problems, dewatering of tailings in the iron beneficiation plant is an important issue (Gomes et al., 2016).

Following the catastrophic failure of the tailings facility at the Corrego do Feijão iron ore mine in Brumadinho, Brazil, in January 2019, which left close to 300 people dead, Gold Fields' operations carried out additional safety inspections at its facilities. ... considering filtered and dry stacked tailings, as well as in-pit tailings ...

Iron ore tailings. A number of representative iron ore tailing samples were acquired from different locations of the dry tailing disposal areas (cf. Fig. 2).As illustrated in Fig. 3, the tailings were loosely dumped as piles; thus, their sampling did not necessitate any particular practice and merely involved filling bags with a hand shovel.A total number of 16 tailing samples, namely T1 to ...
