ABSTRACT. Comprehensive utilization of tailings resources not only solves environmental problems but also creates huge economic benefits. In this paper, fine weakly magnetic particles were extracted from iron ore beneficiation tailings and silica (SiO 2) was separated and purified using a superconducting high gradient magnetic separator.Based on …

Tailings can also contain high residual percentages of valuable ore minerals, indicating the potential for additional resource recovery. ... The REE recovery process typically involves multiple stages; these stages encompass beneficiation, which yields concentrate through flotation, gravity, or magnetic techniques [87].

In terms of tailings development and utilization methods, the primary content contains tailings re-beneficiation, production of tailings building materials or other materials, …

Mining is an important industry, accounting for 6.9% of global GDP. However, global development promotes accelerated demand, resulting in the accumulation of hazardous waste in land, sea, and air environments. It reached 7 billion tonnes of mine tailings generated yearly worldwide, and 19 billion solid tailings will be accumulated by 2025. Adding to this, the …

On November 7, 2023, the US Geological Survey issued a press release announcing that it would invest US$2 million of Bipartisan funding with 14 states to study the …

Dense-medium cyclones have been used for beneficiation of fine particles of coal. In this study, the usability of cyclones in the beneficiation of tailings of a coal preparation plant was investigated. For this purpose, separation tests were conducted using spiral concentrator and heavy medium cyclones with the specific weight of medium 1.3–1.8 (g/cm3) on different …

A typical gravity concentration circuit recovers about 50–60% cassiterite (Lepetic, 1987) but significant values in the fine size are lost in the gravity tailings.Application of flotation and development of selective collectors have made it possible to recover fine cassiterite from the gravity tailings, which has resulted in improvement of overall plant recovery values to over 80%.
