The cemented coal gangue backfill (CGB) in coal mining is normally made of gangue (particle size of 0–15 mm), fly ash, cement, and water. In this study, the effects of the weight content (ranging from 20% to 60%) of fine gangue (0–5 mm) on the microscopic characteristics, resistivity, and compressive strength of CGB were investigated at 3 d and …

From the rod mill the material proceeds to the cobber magnetic separators. Any non-magnetic material which has been released by the rod mill is separated and sent to the tailings thickener. Magnetite iron ore particles are separated by the magnetite separator from the gangue (waste material) minerals in the cobber magnetic separators.

Backfilling is widely used to control surface subsidence and stope stability to improve pillar recovery. Furthermore, it is also an effective way to process and dispose of mining waste such as coal gangue and tailings. In this study, the hydraulic-mechanical properties of cemented paste backfill materials (CPB) were investigated. Twenty-eight cemented coal …

The raw materials used to prepare WSAC include raw coal gangue (RCG), flue gas desulfurization gypsum (FGDG), steel slag (SS), waste stone powder (WSP), and aluminum scrap (AS). RCG, WSP and FGDG were supplied by the Xinwen Mining Group, the Zhongtai coal-fired power plant, and the Shilai Quarry in Xintai (Shandong, China), respectively.

The results showed that it is feasible to use red mud and coal gangue to replace up to 50% of the raw materials to produce cementitious material, which can be called as silica–alumina based cementitious material. The hydration products of RGC are mostly ettringite, calcium hydroxide and C–S–H gel.

These sulfide ores are separated from gangue (waste) material, then from each other, by froth flotation. Copper /Molybdenum Flotation Circuit Steps: Grinding. Grinding mills liberate the ore from the gangue material (non-ores: silica, organics), and reduce it to an optimal size for flotation. Water mixes in to form slurry.

In preparing geopolymer based on red mud (RM), preactivation processes that are generally energy-intensive are employed, including two indispensable steps, namely, calcination and fine grinding. A novel co-grinding preactivation method without calcination was proposed in this study. RM was pretreated by mix grinding with blended coal gangue (CG) (weight ratio of …

Coal gangue (CG) is a kind of solid waste discharged from the process of coal mining and washing without efficient utilization. Motivated by using the CG as supplementary cementitious materials (SCMs) for the partial substitution of cement, the CG was thermally activated via calcining under high temperature and the corresponding mechanism was discussed.

Aiming at the problem of only source material in paste filling and garbage-surrounded city, a system engineering including them was proposed. The construction waste crushing process of filling was optimized based on the gangue process. Compared with gangue, the physical property of three kinds of construction waste ranged widely. Also the paste of all could reach …

Gangue rejection is the process of separating and disposing the poorest, low-quality, low-value material in an ore feed prior to further downstream processing. Simply put, the focus is on the waste to reject, rather than the mineral to recover. Economic benefits are gained when the gangue volume is replaced with useful material of a higher grade.
