Sulfur dispersing agents for nickel sulfide leaching above the melting point of sulfur 来自 circle.ubc.ca 喜欢 0 阅读量: 26 作者: L Tong 摘要: The effects of sulfur dispersing agents (SDAs) in the oxygen pressure leaching of nickel concentrate at medium temperature were investigated. Liquid ...
PURPOSE: To obtain a good quality glass while restraining the formation of nickel sulfide by conducting the electric current to an anode at the upstrearm side in a pool ascending flow zone of molten glass and arranged at the bottom part thereof and keeping the oxidizing state in the bottom ...
The melting point for this neutral melt is 86/sup 0/C; the decomposition potential is approximately 2.0V; the ionic conductivity is measured in the range 97/sup 0/-401/sup 0/C and is 0.142s cm/sup -1/ at 100/sup 0/C, and the density is 2.07g cm/sup -3/. The conductivity ...
Rhodium metal is lustrous and silvery white. Rhodium has a higher melting point and lower density than platinum. It hasa high reflectance and is hard and durable. Upon heating it turns to the oxide when red and at higher temperatures turns back to the element. Where do I find rhodium? It ...
High melting point metallic, e.g., steel mold members are facilely and inexpensively produced by depositing, e.g., flame-spraying, droplets of a melt of a metal having a high melting point onto the fr
The eutectic point of the Ni-NiS system lies between Ni3S and Ni3S2 up to 10 GPa and its composition changes from Ni66 6S33 4 at 0.1 MPa to Ni70 7S29.3 at 10 GPa. The eutectic melting temperature of the Ni-NiS system decreases to 5.1 GPa and 720 K as the pressure increases ...
The microstructure of the MMP Cr3C2–NiCr coating interfacial layer was also investigated by cross-sectional TEM (FEI TECHNI G2 F30 operated at 200 keV with a point-to-point resolution of 0.23 nm). TEM analysis specimens were prepared by mechanical grinding, polishing, and dimpling. ...
Physical constants for more than 280 common inorganic compounds. Density is given for the actual state at 25°C and for liquid phase at melting point temperature.
Al2O3 is added in the slag to reduce the melting point of slag for better meltability, while MgO is added to avoid the crucible erosion. The SiO2 content in the DRI is relatively constant, about 9%, so other components are added proportionally according to the slag composition, which ...
This application gives the use of potentiometric sensor in the determination of the titer value without changing the method. The use of heater DH100 for complete removal of CO2 after the first equivalence point leads to very high precision results. Depending on instrument type, manual operation ...
