“…Another common extraction and recovery process is flotation. Flotation is the most popular mineral processing method and therefore the greatest consumer of water in mineral processing plants (Li et al, 2019). These waters tend to be heavily contaminated with (nonorganic) suspended solids, organic flotation reagents, and heavy metal ions (Li et al, 2019).…”

Resource Recovery From Water

Industrial production of goods and services is at the heart of our modern economy and society, and accounts for approximately 20% of global water consumption (FAO, 2020). This number increases significantly in developed and industrialized nations, as highlighted in Figure 2.1, with industry in Europe and Canada accounting for 54 and 80% of total water use, respectively (FAO, 2020; Statistics Canada, 2014). This water is key to the production of a variety of goods, such as processed food, clothing, chemicals, materials, and energy. Through its use in industry, a portion of this water will inevitably come into direct contact with a wide variety of raw resources, contaminants, or intermediate products, leading to its contamination. This contaminated water is defined as industrial wastewater, and it does not include contributions from agricultural and municipal wastewater discharge. Economic, environmental and safety regulations have driven industrial sectors to systematically manage and treat their wastewater, which can carry undesirable by-products, chemical residues, organics, pesticides, heavy metals, nutrients and minerals, to meet certain standards for process water, rendering it safe to be recycled and/or reused in processes, or returned to the environment. This treatment, which can take the form of mechanical, biological, physical, chemical, and thermal processes, often applied in series, represents a significant cost to industry. For example, in Canada, industrial wastewater treatment and discharge costs represent between 28% and 63% of total industrial water costs, averaging out at about 37% for all industries (Statistics Canada, 2014). Furthermore, in addition to continuous and ongoing growth in high-income countries, rapid industrialization and population growth in developing nations are expected to boost water demand by the manufacturing sector by 400% by 2050 (Marchal et al., 2011). These treatment processes, which amount to annual costs of tens of billions of dollars at a global scale, can, however, present an alluring opportunity to recover resources, reducing the economic burden associated with industrial wastewater treatment.

“…El gran consumo de agua por la minería es uno de los temas más sensibles de la actualidad. Autores como Li et al (2019) comentan que a medida que los problemas por falta de agua se agudizan, el reciclaje de agua en la flotación se convierte en una de las principales opciones para reducir la extracción subterránea de agua, no es la única opción, pueden existen otras, en todo caso les compete a las empresas mineras elegir la opción menos perjudicial para el ambiente. Este panorama obliga a las empresas mineras a adoptar sistemas de tratamiento de agua para mitigar el consumo de agua dulce, así como explorar nuevas tecnologías para la flotación que empleen menos cantidad de este recurso.…”

“…A pesar de que la minería considera al agua como uno de los insumos productivos más importantes y más escasos, en ocasiones, no contempla el derecho humano a este re curso en sus políticas de sustentabilidad (Kemp et al, 2010). Li et al (2019) revisan las fuentes de agua utilizadas por la minería, las tecnologías disponibles para reciclar el agua del proceso de flotación, y las alternativas al agua dulce, y concluyen en aras de conservar este recurso, la minería debería utilizar el análisis del ciclo de vida para el diseño de sus plantas. Otros autores investigan sobre los efectos de la calidad del agua sobre los procesos de flotación, y sus posibles soluciones (Boujounoui et al, 2015;Liu et al, 2013;Muzinda & Schreithofer, 2018).…”

Objective. This article develops a bibliometric study to find out what are the lines of research that analyze mining activity in the 21st century and to find out how many documents on mining have been published, what research areas they cover, as well as who the authors, magazines, organizations, and countries that have published the most. Design/Methodology/Approach. The study analyzes and maps the topics covered by 1,791 documents published in the Scopus database from 2000 to 2019, based on the keywords defined by the authors in their publications, which were later recognized as lines of research. For this, the VOSviewer version 1.6.15 program was used. Results/Discussion. The study identified 44 research lines in seven research groups, of which five are directly related to the effects that mining produces on the environment. In particular, two lines of research stand out: Environmental impact and Economic, ecological and social effects, which account for 25% of the occurrences determined in the study. Conclusions. There is an upward trend in the publication of mining documents in the Scopus database. Notably, research focuses mainly on studying the impacts caused by this activity on the environment and society and its possible solutions. Originality. This study establishes a frame of reference for studying mining activity in the 21st century.

“…Water scarcity and extreme weather in Chile, for example, have made alternative water sources such as desalination increasingly attractive, and regulators have been considering making this mandatory for mining companies since 2011. 38 Mines that upgrade ore using froth flotation are particularly water-intensive, with flotation requiring 3−7 t of water for every 1 t of ore. 39 Improving water reuse in mineral processing has positive material impacts for mines in watersensitive regions.…”

Dewatered and Stacked Mine Tailings: A Review

et al. 2022

Tailings storage is a prescient issue in mining, representing a visible and destructive liability. Dewatering tailings to a paste-like consistency is a popular option to reduce tailings volumes and increase dam safety, but dewatering further to a bulk cake consistency has mostly been reserved for small operations in locations where seismicity or terrain prohibited the construction of dams. The recent high-profile failures of tailings dams such at Fundão and Brumadinho facilities along with the push toward socially conscious investing have generated renewed and urgent interest in tailings dewatering, including stacked (“filtered” or “dry-stack”) tailings. While geochemistry and civil engineering topics relating to tailings in general are both extensively studied, very little academic literature is available specifically on stacked tailings, with discussion mostly confined to conference articles or extrapolation about the behavior of dewatered tailings. Furthermore, the nomenclature around and definition of this method of tailings storage is inconsistent, which can make researching the topic unnecessarily tedious and confusing and, in the worst case, can open the door to intentional misrepresentation of a tailings storage facility’s safety as this is a technology still being scaled up. In this article, the term stacked tailings (ST) is introduced to describe what has been otherwise called filtered tailings or dry-stack(ed) tailings to remedy the inaccuracies with the two existing names and gather the existing literature in one place. Topics covered include the existing definitions of dewatered and stacked tailings; opportunities and barriers to adoption; and construction and general operation for such tailings storage facilities. These are supplemented by an overview of literature in geotechnical and geochemical topics relevant to tailings dewatering (ex. clays) and tailings storage facilities. Emerging dewatering technologies and innovations which might be useful in the scaling up of the technology are also discussed. The aim is to provide a thorough background on the topic for a general audience, outline gaps in the literature, and encourage further exploration of stacked tailings and tailings cake by furnishing a comprehensive list of sources. Stacked tailings are discussed in a rigorous way to make the topic a more approachable way to encourage standardization and adoption, scale up, and the development of associated technologies.
