Study of Low Grade Nickel Laterite Processing Using Palm ...

investigated four catalysts for the dry reforming of methane: three Ni-containing natural ores LN, SN, and NN ores and one Ni-supported Ni-supported NN to solve the problems about unused high-temperature waste heat and CO2 emission in the steel industry. The CO2 conversion ratio was highest for the LN 1.18 wt % Ni, followed by Ni-supported NN 1.0 wt % Ni, SN 0.30

    In order to improve the of , upgrading of was conducted using wet intensity magnetic separator. The was through selective reduction followed by sulphuric acid leaching to recover nickel while remained in residual solid. The Vibrating Sample Magnetometer measured the

  • Chinas lateritic nickel ore market to see 60,000 mt glut

     · A surge in prices of also prompted domestic steelmakers to procure - nickel , with Fe content of around 49%, as an alternative for . SMM calculation based on customs data showed that some 27%, or 610,000 wmt, of - nickel imports in June were consumed in the steel industry


    Accordingly, with the method of the present invention, low grade iron-rich nickel ore, which has heretofore been regarded as uneconomical for refining, can be used for the manufacture of high grade ferronickel. For instance, laterite can be used as

  • Hydraulic Conductivity of Compacted Laterite Treated with

     · The objective of this study was to investigate the effect of tailings IOT on hydraulic conductivity of compacted . The IOT conforms to ASTM C 618-15 Type F designations. In the present study, soil was admixed with 0–20% IOT and compacted at moulding water content ranging from 10 to 25% using four types of compactive efforts
