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

Crushing of rock particles is a phenomenon commonly encountered in geotechnical engineering practice. It is however difficult to study the crushing of rock particles using classical theory because the physical structure of the particles is complex and irregular. This paper aims at evaluating fractal and morphological characteristics of single rock particle. A large number of particle crushing

The maximum particle size of the aggregate used in this test was 10 mm, as recommended by the ASTM and some other studies on the particle size effect [64,71]. The waste rock should be crushed and sieved into 0–0.5 mm, 0.5–1.0 mm, 1.0–1.5 mm, 1.5–2.5 mm, 2.5–5.0 mm, 5.0–8.0 mm, and 8.0–10.0 mm particles.

In civil engineering, particle size > 4.75 mm are coarse aggregates, it can also called “ stone “; The aggregates with particle sizes > 0.15mm and < 4.75 mm are fine aggregates, also known as “ sand “.

To improve the understanding of rock fragmentation, normal repeated impact tests were implemented with marble spheres of different diameters under different impact velocity conditions. The fragmentation process of marble spheres was analysed. In addition, the influences of the particle size, impact velocity and number of impacts on the breakage

The particle size of the SJK granite was between 0.45 and 4.00 mm and is mainly concentrated at 3.00 mm. The particle sizes of these three kinds of rock were distributed in three orders of magnitude, so the influence of the surrounding rock particle size on the spalling slice morphology can be well observed.

Particle size distribution curves of marble to marble/hornfels waste rock reveal these materials are both coarse grained (davg = 23 ± 10 mm) and favor preferential flow regimes. Conversely, intrusive material (found in Pile 5) is significantly finer grained (davg = 1.9 ± 2.7 mm) and favours slower, matrix flow regimes.

Particle size is an important textural parameter of clastic rocks because it supplies information on the conditions of transportation, sorting, and deposition of the sediment and provides some clues to the history of events that occurred at the depositional site prior to final induration.
