Based on Darcy–Forchheimer model was implemented to illustrate the flow during the porous medium. The entropy minimization of the total system is calculated. Suitable variables are implemented to change the obtained mathematical models into an ODE models. Series solutions are derived by adopting ...
Experiments were performed using a Johannes design piston-cylinder apparatus (Johannes et al.1971; Johannes1973) and a CaF2assembly (pressure medium) with a cylindrical graphite oven at 800 and 900 °C and 1000 MPa. Four gently flattened Pt capsules, separated by biotite sheets, were positioned ...
Conclusions Due to the huge amount of ultra-low-grade iron beneficiation, fast detection and accurate extraction of tailings are of great significance to the regional environment's protection and safety management. Using field spectral data and satellite remote sensing image data, this study realized ...
a large amount of tailings was produced and many tailings ponds were established in the mining area. This poses a great threat to regional safety and the environment because of dam breaks and metal pollution. The spatial distribution is the basic information for monitoring the status of tailings ...
