Migration of mineral particles and mechanism of injection plugging during CO2 geological storage in low-permeability reservoirs

open access: yesMeitan xuebao, 2023
CO2 geological storage in low-permeability sandstone reservoirs is one of the effective means to realize CO2 capture, utilization and storage (CCUS). As CO2 continues to be injected into the absorbing layer, some weakly cemented sandstone particles will ...

Analysis iron distribution methods in fine sand- and silt-sized soil particles

open access: yesMethodsX, 2021
Iron is prone to change its form and speciation in phases. Thus, several methods have been developed to estimate iron partitioning in the mineral phases of soils. However, the accuracy of these methods to evaluate the iron contribution from minor phases,

Mineral particle disintegration model

open access: yesIOP Conference Series: Materials Science and Engineering, 2020
Abstract The study proposes mathematical model for reducing the size of mineral particles in crushing and grinding operations, which is a form of the reflected normal Gaussian – Laplace distribution. The study considers the distribution density modification of the mineral particles depending on the magnitude of the energy impact during ...

Calciprotein particles: mineral behaving badly?

open access: yesCurrent Opinion in Nephrology & Hypertension, 2020
Purpose of review Calciprotein particles (CPP) are formed in supersaturated solutions of calcium, phosphate and the mineral-binding protein fetuin-A. CPP have garnered considerable interest as potential mediators of mineral stress, but little consideration has been given to their origin, clearance and role in metabolism.
