The separation of pentlandite from chalcopyrite, pyrrhotite and gangue in nickel projects throughout the world, in Proceedings 12th AusIMM Mill Operators' Conference 2014, pp 153-162 (The Australasian Institute of Mining and Metallurgy: Melbourne).
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 28 d curing times, respectively.

If the gangue mineral in an iron ore is predominantly quartz, reverse flotation is usually used in the cleaning stage to improve the concentrate grade. Figure 9.13 presents a typical flow sheet for processing an oxidized iron ore containing about 30% Fe using a combination of SLon magnetite separators and reverse flotation. The ore is mainly composed of magnetite, hematite, martite, and quartz.
The maximum phosphate adsorption capacity of new discharged coal gangue is over 2.504 mg/g (as P), while the maximum phosphate adsorption capacity of spontaneous combustion coal gangue is over 7.076 mg/g (as P), which indicated that the spontaneous combustion coal gangue is more suitable for use as an adsorbent.

A SAG mill will reduce crushed mineralized material from F80 = 150,000 µm to T80 2000 µm and a ball mill will further reduce the mineral to P80 = 74 µm. A SAG mill measuring 5.8 m diameter and 4.2 m long (3.8 m effective grinding length), powered by a 2000 kW variable speed motor will perform primary grinding of the material in closed ...

Grinding process. The main objective for a grinding process coupled with a froth flotation is liberation of valuable minerals from their associated gangue. Specifically, the goal is to maximize the exposed mineral surface in order to make froth flotation efficient. In Figure 1 a typical mineral locked into a gangue and a sample breakdown can be ...

Coal gangue samples were initially crushed using Jaw crusher (PE60X100), then ground using a planetary mill (QM-3SP2) and sieved to 60–100 mesh (0.25–0.15 mm) to obtain As-received samples.As-received samples then ground using a planetary mill (QM-3SP2) continually for 2 to 20 h at a 35 Hz rotational speed to obtain ...
Mill scale is generated from steel rolling mills and reheating furnaces; it has almost nil gangue content, but is not individually considered for pelletizing due to its poor green bonding property. If both of these two wastes are blended in combined form with hematite ore, the high gangue of slime would be balanced by the gangue free mill scale.
