are 94.93%, 85.48% and 89.34%, respectively. The separation of high-grade sulfur concentrate is good due to the high pyrite content and dissociation degree of the sample. Based on the process mineralogy analysis, the desilting of the high-pressure hydrocyclone was mixed with the feed of original production as a new feed to produce high grade sulfur concentrate. The process can achieve larger benefit......
current of around 5×10-4 pA under VGK=0.6 V, PIN=5 mW/cm2, for a total area of 10 ?m×10 ?m in fully depleted SOI technology. Thus, the LPIN PD-GTE can be suitable for high-grade photoelectric... was adopted in the device as gate electrode to reduce the light absorption. Thin Si film was fully depleted under gate voltage to achieve low dark current and high photo-to-dark current ratio......
on the steel making process, whereby this causes cracks to form in the refractory lining of blast furnaces. In the past, about 1.43 Mt of low-grade and 4.53 Mt of high-phosphorous materials had been transported to low grade and high phosphorous stockpiles, respectively, for future beneficiation. As a result of the progressive depletion of high-grade ore and establishment of beneficiation plant......
and mapping relationship of Cu, Fe, S and SiO2 were investigated by analyzing Cu, S, Fe and SiO2 content variation trends of high-grade matte in copper oxygen bottom blowing bath smelting (BBS... of the content of Cu, Fe and S is constructed, and its forecast accuracy is higher than that of the single factor model, so, it can be applied to the precise control of multicomponent content of high grade matte......
show that the proposed interpolation algorithm can depict the stratiform structure of bauxite deposits and that the uncovered bauxite deposit has high proportions of high-grade and rich ore. The ranges... values of w(Al2O3) and w(Al2O3)/w(SiO2) are 62.82% and 26.96, respectively. These results mean that the uncovered bauxite deposit is of high grade, and the rich ore is relatively concentrated. 3......
depression are respectively affected by western-Yinggehai provenance and Red River provenance, and both of their source rocks are high-grade metamorphic.

are disadvantageous to obtaining a high-grade titanium product. To solve this problem, this study used embedding direct-reduction where pellets without coal were embedded under the coal to be reduced...] ZHAO L, WANG L, CHEN D, ZHAO H, LIU Y, QI T. Behaviors of vanadium and chromium in coal-based direct reduction of high-chromium vanadium-bearing titanomagnetite concentrates followed by magnetic......
, As, and Sb with the controlled potential chloridizing leaching process. The precious metal Au was enriched and high-grade gold mud was obtained, which was sent to sulfation roasting desulfurization......
are distributed within the purple-red calcareous shale. Qujiashan is a high-grade w(MnO)=8.92% to 18.76%) manganese deposit with low-phosphorus w(P2O5)=0.08% to 0.16%) content. It also has a low total REEs...)). Layered ore bodies host in the manganese-bearing rocks. The rocks consist of argillaceous volcanic rock, argillite, carbonate rock and siliceous rock. The deposit is a high grade manganese deposit......
