Unlike tailings of specific high-weight metalliferous rocks, pulps with a low proportion of solids are used in the pumping of less dense tailings such as those from coal treatment (Department of Industry, Tourism and Resources, 2007). The consistency of the pulp depends on the type of tailings, their particle size distribution, their specific ...
A shaker table is also known as a gold shaking table, gold separation table, or concentrating table. It is a fine gold recovery equipment common in the gold shaker wash plant, alluvial gold mining plant to separate concentrates, medium concentrates, and tailings according to material density and grain size.

The tailings solids are typically discharged as a slurry with process waters into storage impoundments like tailings dams, resulting in a waste repository containing both solid particles and liquid pore fluids, which can have high residual concentrations of processing chemicals [4]. The liquids present in tailings, known as tailings water, have ...
The limestone tailings sand was obtained from the limestone mine of China Resources Cement (Hepu) Co., Ltd. The different particle size distribution leads to different filling degrees between aggregates, which has a great influence on the performance of filling materials [34], [35].The fineness modulus was used to characterize the particle …
In some cases, tailings have been used directly as agricultural supplements. Given the global sand shortage (UNEP, 2019), the simple separation of inert sand from a tailings supply can make economic sense. The major research focus for tailings reuse has generally been on substitutions for or in conventional construction materials.
Quarry tailings as solid waste with large output bring a heavy environmental and economic burden. The main objective of this study is to investigate the feasibility of …
A solution lies in high-accuracy, full-bore electromagnetic flow meters with durable liners or protective coatings. With a ±0.2% accuracy, these meters are reliable for consistent, repeatable measurements, even in high-pressure, high-velocity slurry environments. Integrating data output options
Approximately 65–80 billion tons of waste are generated annually after mining operations. Tailings account for ∼ 10–15 billion tons of this total; the remainder is waste rock [1]. The cumulative tailings depositions between 1915 and 2019 are given in Fig. 1 [2]. Download: Download high-res image (177KB) Download: Download full-size …
2. Spiral chutes application in copper Processing. Applying spiral chutes in copper processing plants has revolutionized how raw materials are separated and processed. Using gravity and centrifugal force, the spiral chute effectively separates the copper ore from the gangue minerals, resulting in an efficient and cost-effective …
The optimum Fe grade and Fe recovery of the high-intensity magnetic separation concentrates were 29.46% and 90.88%, which were obtained at the magnetic field intensity of 5000 Oe. Moreover, the Fe grade of the high-intensity magnetic separation tailings was 2.12%, and the yield of the tailings was as high as 58.26%.
