The paper introduces status of tailings resource briefly, and discusses the necessities of comprehensive utilization of tailings in the current economic development …
The mine tailings that are made with the froth flotation method have smaller particles, which makes them more likely to let out contaminants [128]. The mineralogy of mine tailings is strongly dependent on the type of the raw ore, the mineral processing technology, and the degree of weathering during storage in tailings ponds [129].
Iron ore tailings (IOT), the predominant solid by-products of iron ore mining and refining, present significant environmental challenges due to their sheer volume. This paper endeavors to scrutinize the prospective deployment of IOT as an alternative to soft soil in the fabrication of controlled low strength materials (CLSM) for backfill applications.

The tailings pile in Moriah's Mineville hamlet towers over the community and contains the waste from the iron ore extraction process. The mines, now owned by Solvay-North America, a French ...
This Research Topic focuses on progress and achievements of research in sustainable mine tailings (MTs) management. MTs are byproducts generated from mechanical and chemical processes to extract valuable elements from ore deposits.
Shaanxi Province is located in the most important molybdenum ore district in the world, but a lot of molybdenum tailings have been released, polluting the environment and wasting resources seriously. Taking eleven tailing samples collected at the main molybdenum tailings ponds in Shaanxi Province as the research object, the physical, …
Our energy-efficient processes enable recovery of high value minerals from waste stockpiles or tailings, whilst our water management technology allows you to reduce or totally eliminate the need for tailings dams. At CDE we have made it our business to protect, preserve and reinvigorate the environment using the most sustainable methods.
Organic matter (OM) formation and stabilization are critical processes in the eco-engineered pedogenesis of Fe ore tailings, but the underlying mechanisms are unclear. The present 12 month microcosm study has adopted nanoscale secondary ion mass spectrometry (NanoSIMS) and synchrotron-based scanning transmission X-ray microscopy (STXM) …
Rare earths have appeared in the market with new energy and Information Technology and Communications (ITC) applications. While their demand grows exponentially, their production is experiencing a bottleneck given that their deposits are concentrated in very few locations, mainly in China. This scarcity and dependence have …

Metals X, which owns a 50% equity interest in Renison though its 50% stake in BMTJV, expects to make permitting applications for the construction of a "new high …
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 …
The line between valuable ore and waste is not clear, ... is a potential technology in the tailings treatment, especially when valuable metals are incorporated to sulphide minerals, such as cobaltiferous pyrite ... digital platforms can facilitate the valorisation of mine tailings by new and alternative waste-to-resource matches. Digital ...
The comprehensive utilization technology of iron ore tailings has played an important role in the green mine construction and social and economic sustainable …
