Gangue/ lode mineral processing technology

2021-3-31 · Gangue/ lode mineral processing technology. Gangue also named as lode mineral, gangue minerals are generally non-metallic minerals, such as calcite, Quartz, kaolin, talc, water mica, chlorite, epidote stone, etc. Types of gangue minerals, content and the symbiotic relationship between the level of ore processing method selection and processing costs tend to have an important impact.

Compressive deformation and energy dissipation of

2016-9-1 · Crushed gangue, an inhomogeneous and discontinuous medium, is accompanied with the absorption and dissipation of energy under compression. In order to study the compressive deformation and energy dissipation of gangue in the loading process under conditions of different particle sizes, loading rates, and first-time stress loads, a SANS testing machine and steel cylinder were used to

Influence of block shape on macroscopic deformation

2021-2-12 · When crushed gangue samples are compressed to ε = 0.4 under the confining pressure of σ 3 = 1.0 MPa, the fragmentation degree (FD) of the samples is ordered: FD knife > FD disk > FD bar > FD cube, corresponding to the number of fractures of 6379, 6101, 5886 and 5639, respectively. The results show that the worse the regularity of block shape, the more likely it will be broken, the more unstable the skeleton force chain structure, and the worse the bearing capacity of the crushed gangue
