Image Extraction of Tailings Pond Guided by Artificial
The large number of tailings ponds in my country, coupled with various man-made and natural factors in recent years, leads to the frequent occurrence of tailings pond accidents, causing serious harm. Mastering the number and distribution of tailings ponds is of great significance to prevent tailings pond accidents and carry out emergency To increase resource efficiency, mining residues–especially tailings–have come into the focus of research, companies, and politics.

Data-driven modelling of the flocculation process on mineral processing
CPB is an engineered composite material produced with MPT, hydraulic binders and mixing water (Fig. 1).Before CPB preparation, the tailings slurry from the milling or processing operation needs to be dewatered as it contains dispersed particles that hinder the consolidation and strength gain of CPB (Bussière, 2007).Dewatering process is The clarification of tailings slurry using polymer flocculants has been widely used in the mining industry to promote the cleaner production of mineral resources.In this paper, a data-driven prediction model was proposed using gradient boosting machine (GBM) for the non-linear relationship modelling and firefly algorithm (FA) for GBM hyper Data-driven modelling of the flocculation process on mineral processing

An alternative to the disposal of tailings is to put the waste to good use. For example, manganese tailings may be used in agro-forestry and as coatings, resin cast products, glass, ceramics, glazes as well as building and construction materials (Verlaan and Wiltshire 2000). In future, base metal tailings and low grade metal ores may be Mining is an important industry, accounting for 6.9% of global GDP.

Tailings: Dangerous Wastes or Precious Treasures?
Tailings often contain trace elements such as Zn, Mn, Cu, Mo, V, B, Fe, and P, which are essential for maintaining plant growth and development. The tailings discharged by some dressing plants in Japan are alkaline. In the rice planting experiment, these tailings neutralize acidic soil and can improve the quality of acidic soil.To increase resource efficiency, mining residues–especially tailings–have come into the focus of research, companies, and politics. Tailings still contain varying amounts of unextracted elements of value and minerals that were not of economic interest during production.

Process Water Management and Seepage Control in Tailings
In the past thirty years many mining projects in Chile and Peru have used: (i) polymeric geomembranes and (ii) design-and-build cutoff trenches, plastic concrete slurry walls, and grout curtain systems to control seepage at tailings storage facilities (TSFs). Geosynthetics are a viable alternative at a TSF dam for clay cores or impermeable It was found that tailings could be almost monomineral and contain up to 90 wt% of monazite. Tailings from the Singkep Island,and in particular that from the Kebun Nyjur area, contain up to 5807 ppm REE and are therefore of high economic potential.
