. [19] WANG Z H, ZHENG S L, WANG S N, LIU B, WANG D W, DU H, ZHANG Y. Research and prospect on extraction of vanadium from vanadium slag by liquid oxidation technologies[J]. Transactions of Nonferrous......
little difference. The element Cu is often associated with organisms, and the enrichment of Cu can represent the prosperity of living matter in a lake [56]. In an oxidation state, the element U......
to the risk of oxidation of specimens, the heating process was performed in atmosphere of nitrogen with the flow rate of 150 L/h. Simultaneously, the cooling of the cylinder with boron trichloride started......
of the thickness of oxide layer on the sensing characteristics was not negligible. So they grew well-controlled layers of silicon dioxide on the metal surface to avoid oxidation, which maintained high......
or oxidation ditch process. Except the SS1 feedstock with anaerobic digestion, the other three SS feedstocks are directly dewatered mechanically by the belt or rotary press filter after being concentrated......

(2020) 27: 3544-3566 DOI: https://doi.org/10.1007/s11771-020-4509-5 Numerical simulation research on response characteristics of surrounding rock for deep super-large section chamber under dynamic and static combined loading condition FAN De-yuan(范德源)1, LIU Xue-sheng(刘学生)1, 2,......
oxidation of pyrite reduced the pH of groundwater to 2-4 around some tunnels in Norway. This sulfuric acid attacked the sprayed concrete of road tunnels, resulting in cracking and spalling of tunnel......
steel mold positioned in the directional solidification apparatus, which was previously coated with alumina, and subjected to forced argon gas flow to avoid both oxidation and loss of metal......

) shown in Fig. 22(a) represents the oxidation of the activation products. And the cathodic wave (C2) shown in Fig. 22(b) represents the reduction of the activation product. The detailed... collector in the flotation. As for sulfide minerals, ion-exchange and oxidation-reduction govern the interactions between metal ions and minerals. Research approaches like micro-flotation tests, contact......
