Scientific Considerations for the Assessment and Management of Mine
Assessing Mine Tailings Disposal Options. Mine tailings management and/or disposal options are important considerations for government regulators during the EIA approval process associated with new mining activities. Each site will have a different set of constraints, which will influence the decision on the tailings disposal options.
Solutions to Mine Tailings
Our modular mining solutions for mine tailings are in operation across many mine sites around the world, helping operators divert tens of thousands of tons of materials from tailings dams every month. This is reducing the need for large tailing dams and allowing mine operators to rehabilitate land for other uses. We do this through:
Mine tailings: reprocess, recover & recycle
Yes, that number would need to be offset against the capital cost of new equipment if required, higher processing costs etc. but, given that average ore grades are declining and operating costs are rising, there are now some cases where the …
Mine tailings: How to effectively manage the risk
While the tailings risk is unlikely to affect the actual mining effort; a collapsed tailings dam can destroy the mine's value as well as a company's reputation and licence to operate. Rather than look at tailings in isolation it actually makes more sense to include it as part of water management.
Solutions to Significantly Reduce Tailings Waste and Risks
Looking at tailings-pond construction and processes in isolation won't create systemic change. A holistic complete-mine view is required, one that includes a deep dive into energy and water footprint, platform technologies and process changes.
Tailings potential: recovering metals from mine waste streams
Experts believe mine tailings could provide a new source of metals and minerals critical to the energy transition, while also cleaning up the environment.
A review of circular economy strategies for mine tailings
Finnish tailings contain considerable amounts of metals. • Holistic circular economy approaches are needed to manage the waste streams. • Technologies to recover metals and to use mineral residues are available.
Mine Tailings: The Cornerstone of Safe Mining Operations
What are Mine Tailings? In mining, tailings refer to the residual waste material that remains after the desired minerals have been separated from the ore during the mining process. These typically consist of finely ground rock particles, water, and traces of chemicals used in the extraction and separation processes.
How to handle mine tailings safely and sustainably?
The paradigm is shifting, as technology is evolving towards the adoption of smart and hybrid solutions that maximize ore and water recovery while optimizing operational costs.
New Tailings Reprocessing Technology Has Environmental Benefits
Some mining companies are figuring out ways to turn tailings to profits with novel reprocessing technologies to extract valuable metals from the waste.

•The need for a unified approach to tailing dumps at different stages of their life cycle 2 •The need to synchronize the verification, assessment of the safety level and prescribing measures to improve the safety of tailing dumps 3 •The need for efficient use of limited resources to verify and improve the safety of tailings storage facilities
Tailings solutions: How to filter down the options
As the need for dry stack tailings has increased, so has the need for larger and larger dewatering equipment to accommodate the potentially huge volumes of tailings slurry. Some large mining operations process over 100,000 dry tonnes of flotation tailings per day. It is widely held that fewer / larger pieces of equipment reduce both operational ...
The Reprocessing and Revalorization of Critical Minerals in Mine 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 …
