The metal content in tailings (0.3 wt-%) is reached around Scenario 3, which could be very relevant in the near future as current tailings still contain a significant amount of Ni that could soon become economically viable to recover if the average ore grade in the mines decreases to that extent.
1. Introduction. The acid-leaching tailings of laterite nickel ore are a hazardous waste generated by the laterite nickel ore industry [1], [2], [3].As global demand for nickel continues to rise and nickel sulfide resources decrease, the extraction of nickel resources from laterite nickel ores the main development trend of the global nickel …
Fig. 2 illustrates the iron ore beneficiation process, particularly magnetic separation, resulting in the generation of inevitable tailings. Due to the characteristics of iron ores and the conditions during beneficiation, it is inevitable that approximately 2.5–3 tons of IOTs are generated for every 1 ton of iron ore concentrate produced [7].In 2019, …

The composition of low-grade laterite ore from Yuanjiang, Yunnan, China was tested by chemical analysis. Under 7% of CaF 2 for the adjuvant agent and 8% of anthracite for the reducing agent, the main metal nickel and iron in laterite ore (100 g) can be efficiently recovered after high temperature (1250 °C) reduction. The process is …

In 2019, when the Brumadinho tailings dam breached at the Córrego do Feijão iron ore mine in Brazil, wiping out an entire village and killing 270 people, the world determinedly turned its attention to mine tailings facilities.. Tailings are an unfortunate, but inevitable, part of the mining process and Brumadinho was not the first – and likely won't …
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 …
Pressure acid leaching has been applied to the Caron process to reduce high-energy consuming phases in direct ore leaching. Direct leaching eliminates the need for drying and reduction steps, which then leads to energy savings (Buyukakinci, 2008).The acceptable nickel content in this method is 1–5% (Dalvi et al., 2004).Also, the crushed ore is …
Many different mineral commodities are important to modern society. However, when mineralogists think about mining, they are generally thinking of ore minerals that are the sources of important metals, or of minerals that have specific, highly valued properties (e.g., asbestos, micas, potash, and gems of all sorts).That is what we will focus on in most of …
