The static digestion experiment showed that the concentration of heavy metals under acidic and alkalic conditions were both higher than those at neutral,except that the concentration of Cu under alkalic was higher than that under acidic and others in the order of acidic>alkalic>neutral.

Both the load and the displacement of the ram as well as their relationship during extrusion which directly follows liquid infiltration were experimentally measured and analyzed.

A numerical simulation technique based on the stable alternating direction implicit (SADI) method and the upper bound element technique(UBET) is presented and applied to simulations of extrusion directly following liquid infiltration which involves infiltration,solidification, and large plastic deformation in one process.

Mechanical Properties of Alumina Short Fiber Reinforced Aluminium Matrix Composites Fabricated by Extrusion Directly Following infiltration;

Infiltration process of fiber reinforced magnesium aluminium matrix composites made by liquid infiltration was mainly studied in the paper.

Dynamic leaching experiment was conducted to evaluate the desorption rule and effect of Na+, Al3+, Fe2+, Zn2+, Ca2+ and Mg2+ absorbed deposed diatomite while SO42- was evaluated by static soaking experiment.

In this paper, the Copper sulfide-mine tailings in Guangxi province was taken as experimental sample, the static soaking experiments and dynamic leaching experiments were carried out to investigate.

To evaluate and predict the environmental hazard from molybdenum mine tailings,the law of ion release of molybdenum mine tailings was investigated by continuous static soaking experiments for 105 days and periodically monitoring the pH values and ionic concentrations of copper and lead in the soaking solutions.
