“…This flow sheet can potentially enhance the overall performance of the circuit since the thickener receives a lower solids concentration. Consequently, a higher solids concentration is expected from the thickener s underflow [138]. In this situation, there is an elevation in the fine fraction of the thickener feed, potentially posing a thickening challenge.…”

“…Hydrocyclones rely on centrifugal force to either concentrate or classify solids within the feed suspension [137]. However, due to their inherent characteristics like size, shape, and density-based classification, it is unavoidable that one stream will carry a lower percentage of solids with finer particles while the other stream will contain coarser particles with a higher solid content [138]. Numerous hydrocyclone sizes are available, with cylinder diameters ranging from 1 to 30 cm and cone angles between 25 • and 50 • [127].…”

“…Hydrocyclones can achieve optimal dewatering performance by configuring them with the right geometry and inlet pressure, as researchers have found that a conicalshaped extension improves overall productivity [127,141]. The potential application of hydrocyclones for dewatering copper concentrate tailings in cement paste backfill showed that using smaller apex diameters and larger vortex finder diameters resulted in a higher solid content in the underflow [138]. Additionally, reducing the cone ratio led to a decrease in the solid content of the underflow.…”

“…Additionally, reducing the cone ratio led to a decrease in the solid content of the underflow. By selecting the appropriate geometry and solid content, a potential increase of up to 71% was achieved [138].…”

The mining industry is confronted with substantial challenges in achieving environmental sustainability, particularly regarding water usage, waste management, and dam safety. The increasing global demand for minerals has led to increased mining activities, resulting in significant environmental consequences. By 2025, an estimated 19 billion tons of solid tailings are projected to accumulate worldwide, exacerbating concerns over their management. Tailings storage facilities represent the largest water sinks within mining operations. The mismanagement of water content in tailings can compromise their stability, leading to potential dam failures and environmental catastrophes. In response to these pressing challenges, the mining industry is increasingly turning to innovative solutions such as tailings dewatering and water reuse/recycling strategies to promote sustainable development. This review paper aims to (I) redefine the role of mine tailings and explore their physical, chemical, and mineralogical characteristics; (II) discuss environmental concerns associated with conventional disposal methods; (III) explore recent advancements in dewatering techniques, assessing their potential for water recovery, technical and economic constraints, and sustainability considerations; (IV) and present challenges encountered in water treatment and recycling within the mining industry, highlighting areas for future research and potential obstacles in maximizing the value of mine tailings while minimizing their environmental impact.

“…It is one of the commonly used classification equipment for tailings backfill. It has the advantages of simple structure, low equipment cost and small occupation area [25,26]. In recent years, with the continuous maturity and development of the application of hydrocyclone in tailing backfill field, a hydrocyclone group, which is formed by several or dozens of hydrocyclones, began to appear and be applied in the backfill system of mines (see Figure 7a).…”

With the development of science and technology, backfill technology has made continuous progress, and the traditional backfill method is no longer suitable for various complicated practical engineering situations. Therefore, researchers in the field of backfill mining have gradually shifted their research focus to the study of high-concentration backfill, and Chinese researchers are no exception. In order to solve the problems caused by the traditional backfill method, China began to vigorously develop high-concentration backfill in recent years, and achieved a lot of results. In this paper, some important achievements made by Chinese researchers on high-concentration backfill in recent years are reviewed; it also presents a summary report of the latest research results from several key laboratories across China. Therefore, this paper reviews the development progress of high-concentration backfill China has made, of which the main contents include: (1) research progress of the high-concentration backfill theory in China; and (2) research progress of high-concentration backfill equipment in China. Finally, we claim that this paper serves just as a guide to start a conversation, and we hope many more experts and scholars will be interested and engage in the research of this field.
