Belüftung der Stollen während des Vortriebester than its performance when forming other flow patterns. The total dust removal efficiency can be more than 99%, the classification efficiency of PM2.5, the particles above 5 μm, and the particles above 10 μm are more than 98.35%, 99%, and almost 100%, respectively, when the liquid–gas volume ratio is more than 0.004.

Application of Carbon-Based Oxygen Evolution Reaction Electrocatalyst in Zinc Electrowinning Systemctrolyte is 389 mV (@ 10 mA cm.). Meanwhile, the prefabricated catalyst is directly used as an anode in the zinc electrowinning system (50 g L. Zn. + 150 g L. H.SO.) to measure the cell voltage. Compare with the traditional pure lead anode, the cell voltage decreased in a short time during the zinc electrowinning process.

Characteristic Studies of Critical Rare Earths Scandium and Yttrium from Circulating Fluidized Bed Cents. The variables including reagent concentration, leaching time, and temperature in the range of 1.5–4 mol/L, 5–120 min, and 25–80 °C were optimized. The leaching efficiency of scandium and yttrium were at 48 and 45% under the optimized conditions.
