industrial minerals or rock are finely graded by passing them through a feed unit 14 into a cycle 19, 22, 38, 39,41 comprising a cryogenic liquid, for example liquid carbon dioxide, and passing this cryogenic flow with the mineral particles contained to a fine grader 17 through a zone ther...
The reuse of mining waste-rocks as construction material constitutes an innovative management approach consistent with the principles of sustainable development. Nevertheless, the implementation of this approach is still limited by most guidelines due principally to insufficient knowledge of these materials ...
aBrecciation is a prominent fault process in low-porosity settings such as within crystalline rocks, and carbonates (Sibson, 1977; Sibson, 1986). Breccia is fault rock composed of angular, coarse-grained fragments that formed via high-density fracturing (brecciation), which are embedded in a ...
Method and apparatus for fine distribution of particles of coarse crushed coal, ores, industrial minerals and rocksCoarse-crushed particles of coal, ore, industrial minerals or rock are finely graded by passing them through a feed unit 14 into a cycle 19, 22, 38, 39,41 comprising a cryogenic...
The fineness modulus of the fine aggregate grading zone II from the local river was 3.16. In addition to the solid waste coarse aggregates, introduced in Section 2.1, the natural coarse aggregate was continuously graded limestone gravel from 5 to 20 mm. The test water was from tap water. ...
The rock composition of thick-layer, coarse-grained clastic reservoirs is complex. There are large variations in granularity and poor selectivity. Reservoirs of thick-layer, coarse-grained clastic rocks are extremely heterogeneous. Current conventional parameters for quantitative characterization of reservoir...
