Effect of limestone and dolomite tailings' particle size

The aim of the study is the investigation of potentially toxic elements adsorption on limestone, dolomite and marble particles of different size. As parameters, rock particle size, solution concentration, contact time and presence of other elements in the solution have been investigated. Four fractions with different particle size (-4mm + 1mm, -1mm + 315μm, -315μm + 90μm, <90μm) have

Discrete Element Modeling of Crack Initiation Stress of

Investigating the crack initiation stress of rocks is vital for understanding the gradual damage process of rocks and the evolution law of internal cracks. In this paper, the particle flow code method is used to conduct biaxial compression tests on a marble model with an elliptical crack under different confining pressures. According to the evolution status of microcracks in the rock during

Energy Dissipation and Particle Size Distribution of

To investigate energy dissipation and particle size distribution of rock under dynamic loads, a series of dynamic compression tests of granite specimens were conducted using a conventional split-Hopkinson pressure bar (SHPB) device with a high-speed camera. The experimental results show that the dissipated energy increases linearly with an increasing incident energy, following two different

Marble is a metamorphic rock formed by the high temperature and high pressure of the original rock in the earth's crust. A forced turbine grading system is used to extend the finished particle size range from the original 80-325 mesh range to the 80-600 mesh range. The grading interval is large and the precision is high.

Particle Size Result Interpretation: Number vs. Volume

Interpreting results of a particle size measurement requires an understanding of which technique was used and the basis of the calculations. Each technique generates a different result since each measures different physical properties of the sample. Once the physical property is measured, a calculation of some type generates a representation of a particle size distribution.

A bonded-particle model for rock - ScienceDirect

A numerical model for rock is proposed in which the rock is represented by a dense packing of non-uniform-sized circular or spherical particles that are bonded together at their contact points and whose mechanical behavior is simulated by the distinct-element method using the two- and three-dimensional discontinuum programs PFC2D and PFC3D.

Characterization of particles and particle systems

Particle size, in the sense commonly used, is a linear length measure, measured in SI unit [m]. In this sense it can be uniquely defined only for spheres, where it is the diameter (or radius). For all other shapes, particle size must be clearly defined via the measuring procedure.

Geology - rocks and minerals

Marble Marble is a metamorphic rock formed when limestone is exposed to high temperatures and pressures. Marble forms under such conditions because the calcite forming the limestone recrystallises forming a denser rock consisting of roughly equigranular calcite crystals. The variety of colours exhibited by marble are a consequence of minor amounts of impurities being incorporated with the
