“…However, the beneficiation of hematite-goethite ores has significant implications as goethite can generate more fines during comminution and can carrier for impurities. The concentration of hematite-goethite ores includes wet technologies as spirals, hydrocyclones, and wet magnetic separation (Nunna et al 2020). Then, the demand for technologies with lower water demand has increased, and research has been carried out for the dry processing of hematite-goethite ores.…”

“…Then, the demand for technologies with lower water demand has increased, and research has been carried out for the dry processing of hematite-goethite ores. Thus, dry processing technologies such as dry desliming of iron tailings by air classification (Suthers et al 2019), dry density-based gravity separation using fluidized bed technology (Oshitani et al 2013), and thermal roasting followed by magnetic separation (Nunna et al 2020) has been studied.…”

Mining resources have played a leading role in the development of humanity, and the demand for these raw materials is expected to increase in the foreseeable future. In addition, new technologies also require the extraction of new critical materials. These trends pose various challenges as there is a limited supply of natural resources, and standard mining and mineral processing practices are associated with significant environmental impacts, such as waste generation, energy and water consumption, and CO 2 emissions. The circular economy (CE) has recently gained attention as a model to address such a complex scenario. This work analyzes the current efforts towards the application of CE in mineral processing. Although advances have been made, this review shows that the most significant material flows and environmental impacts occur near the production sites, which currently limits the closure of loops. Besides, mining industries are conservative regarding the adoption of new technologies or processing strategies, which is another hindrance to the implementation of the CE. Thus, and with few exceptions, while some sectors are already facing advanced stages of CE (namely, CE 3.0), the mineral processing field struggles to advance from the basic CE requirements (i.e, CE 1.0 to CE 2.0).

“…It is known that some developments of dry technologies and equipment have been applied in various industries [1,2], including in magnetic separation of iron ores [3][4][5]. In the beneficiation of mineral raw materials, this is primarily the absence of the need to use process water, filtration, thickening and drying of beneficiation products, which leads to savings in financial resources and energy costs [6,7]. The relevance of the direction under study is associated with the high consumption of process water in mineral beneficiation, which in the conditions of the Russian North is fraught with excessive costs and increased environmental impact and is confirmed by the experience of operating beneficiation plants in Yakutia.…”

The article presents the results of research on the development of processes and equipment for ore preparation and pneumatic dry beneficiation of mineral ores. The methods of crushing and grinding before enrichment of minerals have been considered, dry enrichment of geomaterials is investigated. Highly efficient prototypes of beneficiation equipment are developed and tested: crushers of multiple dynamic impact RD-MDV-900, DKD-300, centrifugal grinders CMVU-800 and VCI-12, pneumatic separator POS-2000. Fundamental designs are created, and a number of new ore preparation and pneumatic beneficiation instruments are being designed. The efficiency of approbation of an autonomous dry beneficiation complex with new safe environmental standards for the processing of gold-bearing ores, which makes it possible to fully release and extract free gold with a particle size from 10,000 to 100 µm, is shown. The introduction of the dry beneficiation method is very promising for the mining industry. It will allow to reduce capital costs for the construction of stationary beneficiation plants, completely or partially withdraw from the use of process water, the construction of a water supply system, a traditional tailing dam, etc.
