The burgeoning accumulation of vanadium-titanium magnetite tailings (VTMT) presents a dual challenge of environmental hazard and loss of valuable metal resources. This review arrives at a crucial juncture in global efforts towards a circular economy, focusing on innovative and effective metal recovery technologies. We explore …
Tailings from mining operations are usually stored in large tailings dams as a slurry that contains the waste materials from the beneficiation process. This slurry includes mineral material, metals and any reagents used in the beneficiation process.
The re-processing of mine tailings to obtain critical raw materials (CRMs) could reduce the mining of new deposits as well as ensure the profitable us…
Dewatered tailings technology filters and extracts water from ore processing waste to produce a paste or bulk cake-like consistency. How much water can be removed depends on the type of tailings, but in a classic dewatered set-up, experts say volumes are expected to be reduced by around 30–40%. This water can then be reused in the …
Given the high impact of traditional mining, the recovery of rare earth elements (REEs) from hazardous waste materials could become an option for the future in accordance with the principles of the circular economy. In this work, the technical feasibility of REEs recovery from metal mine tailings has been explored using electrokinetic …
This method has low equipment investment and production costs, but a single gravity process may sometimes fail to meet the requirements of the comprehensive recycling and recovery of gold tailings.
Mine tailings, the byproduct of mining and mineral processing, are increasingly mass produced as a result of increased demand for metals and minerals as well as the advancement in technology that allows for the exploitation of lower-grade ores. Lower grades can increase the volume of tailings that may contain new gangue minerals that …
This chapter provides an overview of mine tailings and mine tailings facilities. It illustrates why and how mine tailings are produced, and the complexity involved in the long-term storage and management of this waste product. The call for a global standard for mine tailings management is a response to recent catastrophic facility failures. Mining …
Recycling of tailings in raw-material-intensive applications presents an interesting alternative to costly tailings management with associated restoration efforts. Chemically bonded ceramics may offer a route to upgrading mine tailings into raw materials for ceramics.
At present, the comprehensive utilization of tailings is a topic of global concern. After several years of research, Almalek Mining Company has finally successfully realized the recycling of tailings from the Yingjika tungsten mine …
Abstract. This study investigated the engineering properties and leaching behavior of controlled low-strength materials (CLSM) containing arsenic-rich mine tailings and evaluates the feasibility of the tailings as source material for CLSM.
The present study proposes three distinct processes to recycle rare earth elements (REE) from two low-grade secondary resources: REE-containing mine tailings and ferrous scrap from shredded waste of electrical and electronic equipment (WEEE). The first developed process extracts both REE and phosphorus from the apatite mineral …

The product is used to recover tailings in the iron ore dressing process, not make mineral powder run away, and make full use of resources effectively. The equipment has the characteristics of high recovery efficiency, small volume, easy layout, large processing capacity and remarkable economic benefits.
Mitigating tailings risk with filtering and co-disposal. Fueling the energy transition will require mining more critical metals; however, as production of raw materials grows, so do the waste streams at each mine site. In Canada, 80% of the tailings are managed conventionally. It is estimated that nickel, lithium and cobalt production needs …
This method has low equipment investment and production costs, but a single gravity process may sometimes fail to meet the requirements of the comprehensive recycling and recovery of gold …
The increasing amount of solid waste, e.g., waste tyres from car industry and tailings from mine operations, causes substantial environmental and soci…
When it comes to managing tailings, producers have a variety of equipment options to help them reduce the volume of slurry material reporting to the settling pond or tailings storage facility (TSF). One of these options is a Thickener, a liquid-solid separation device that can be used alone or as part of a larger tailings …
Tailings Storage Facilities (TSFs) Message from the CEO. Over recent years, the mining industry has experienced several tailings dam failures resulting in catastrophic loss of life and environmental damage. At Glencore, we recognise the possibility of a tailings storage facility (TSF) failure as a material risk with the potential to result in ...
