Review on metal extraction technologies suitable for critical metal
The extraction of critical metals in a circular mining system begins with mineral processing (Fig. 2).Mineral processing involves liberating and concentrating economical metals and minerals from a mined resource using comminution (particle size reduction), classification (particle size screening), and separation technologies (e.g., 5. Tailings management within the circular economy in mining. In this chapter, the possibilities to manage the mine tailings with reduce, reprocessing, upcycle, downcycle and disposal strategies are discussed. In the subchapter 5.2, an inventory of the metal content of mine tailings in Finland is presented. 5.1.A review of circular economy strategies for mine tailings

Minerals Free Full-Text AI4R2R (AI for Rock to Revenue): A
In the last few years, jargon, such as machine learning (ML) and artificial intelligence (AI), have been ubiquitous in both popular science media as well as the academic literature. Many industries have tried the current suite of ML and AI algorithms with various degrees of success. Mineral processing, as an industry, is looking at AI for two Real-time analysis and digital process control (Principle 11) induce more efficient processes (Principle 4), while combination of circular hydrometallurgy with zero-waste mining (Principle 12) is a form of process intensification (Principle 4) as it allows to largely omit mineral-processing operations, linking mining directly to hydrometallurgy.The Twelve Principles of Circular Hydrometallurgy Journal of

Circular economy in mining and metals AFRY
AFRY is committed to sustainable mining, minerals processing and metals production. Sustainable mining promotes resource efficiency, minimising waste, and embracing recycling and circular solutions. As engineers and consultants, AFRY can take an active part in accelerating the pace of change towards sustainable mining and metals.The circular economy can provide some answers to the challenge of mineral material availability. Many factors stand in the way of a 100% circular economy, including loss of materials, long residence times in the economic system, the economic expansion of emerging countries, government policies and new uses.Mineral resources and the circular economy BRGM

In mining, not everything is a circular economy: Case studies from
The simplistic model of the current concept of the circular economy seems to have serious application challenges when applied to the industrial use of mineral resources.Given the importance and characteristics of the waste that inevitably accompanies the production of metals and minerals, it is necessary to separate those that are For instance, the detrimental effects from tailings, open-pit mine wastewater, mineral processing wastewater, and wastewater from various laundry activities, particularly in hazardous mining sites, also Various Options for Mining and Metallurgical Waste in

The minerals industry in the era of digital transition: An energy
This review is divided into seven sections (Fig. 1) with the goal of providing a summary of energy-efficient and environmentally conscious extraction and processing of minerals in the age of digital transformation.The introduction provides background information and explains existing problems. In the energy consumption and innovative Comminution is particularly critical in the energy balance of mineral processing (more than 50% of the energy needed to produce a metal is spent at this stage with an efficiency of barely 5%). In addition to energy efficiency, the challenge of ensuring material efficiency and the reduction of final waste is now emerging.From mineral processing to waste management and recycling:

Ep. 16 A Week of Circularity: All Minerals Considered
An example of co-investment is Tesla, who stated in 2021 that it would deploy $1 billion AUD a year on battery raw materials from Australia. One of the attractions in Australia, besides its mineral deposits, is its expertise in mining. Ford and Toyota are also co-investing in critical mineral processing in the region.This paper presents a review of chemical composition data of the main stages of copper production from sulfide minerals, such as (1) copper minerals, (2) flotation tailings, (3) flotation concentrates, (4) slags and (5) flue dust from the smelting/converting stage, (6) copper anodes, (7) anode slimes, (8) contaminated electrolytes from the Minerals Free Full-Text Chemical Composition Data of the Main
