“…The grade was changed probably because of the selective comminution between valuable materials and gangue materials. Similar reports can be found in the literature (Hesse et al, 2017;Tong et al, 2013).…”

In this study, the beneficiation performance of chrome from the high carbon ferrochrome slag (HCFS) was evaluated. The mineralogical characteristics of HCFS was investigated first, and then HCFS was treated by magnetic separation, gravity separation, magnetic-gravity combined separation, and gravity separation after grinding respectively, to recover the Cr2O3. Finally, the Fuerstenau upgrading curves were used to evaluate the separation performance of different separation processes. The results indicated that the gravity separation process with a proper grinding condition gave the optimum beneficiation performance. A concentrate product with 30.18% Cr2O3 grade and 22.52% recovery was obtained from the HCFS.

“…Hal ini dikarenakan biaya ekstraksi yang lebih murah. Peningkatan permintaan secara global dan fluktuasi harga logam nikel di pasar komersial, serta berkurangnya cadangan bijih nikel sulfida, maka industri metalurgi mulai beralih untuk menggunakan bijih nikel laterit sebagai bahan bakunya (Tong et al, 2013).…”

The Leaching of Low-GradeNickel Laterite Ore Using Atmospheric Acid Leaching Method in Hydrochloric Acid. Nickel laterite extraction using the hydrometallurgical method is more efficient in energy consumption with less exhaust gas than the pyrometallurgical method. This method causes the extraction of lowgrade nickel laterite ore using hydrometallurgy could be more effective. One of the hydrometallurgical methods to extract nickel from its ore is atmospheric acid leaching. This research aims to determine the percentage of nickel recovery through the leaching process, determine the most influenced leaching factor, and determine the optimum leaching condition. The main factors that influence the leaching process are temperature, acid concentration, and leaching time. Atomic adsorption spectroscopy was chosen to analyze the leaching solution. This research showed that the lowest recovery of nickel leaching was 9,40% of Ni, and the highest was 75,76% of Ni. Analysis of variance (ANOVA) was used to determine the most influenced factor of leaching. The most influenced factor was temperature (A), followed by acid concentration (B), duration (C), interaction of acid concentration-temperature

“…The growth of stainless steel and electric vehicle battery production has led to a corresponding increase in the demand for nickel processing (Guo et al, 2018;Li et al, 2019). Low-grade laterite ore, which accounts for approximately 60% of the world's nickel ore reserves, has attracted much attention owing to the dwindling supply of sulphide nickel ore (Tong et al, 2013;Li et al, 2017). However, studies have shown that conventional pyrometallurgical and wet leaching processes are unsuitable for nickel recovery from low-grade nickel ores (Poumaderi et al, 2014;Quast et al, 2015;Sadowski and Pawlowska, 2017;Javanshir et al, 2018).…”

In this study, the effects of red mud (RM) dosage during the co-reduction roasting of lowgrade laterite ore and RM were investigated. The expanded test was conducted under the following optimized conditions: RM-1 dosage of 15 wt%, anthracite dosage of 13 wt%, a roasting temperature of 1300 o C, and roasting time of 3 h. Ferronickel powder was obtained with a nickel grade of 1.95 wt%, iron grade of 83.25 wt%, and nickel and total iron recoveries of 94.71 wt% and 95.98 wt%, respectively. The addition of RM improved the recovery of nickel and total iron in ferronickel powder. The reason was because of the increased intensity of the diffraction peaks of kamacite and iron, and the ferronickel particles grown due to the liquid phase were easier to achieve at a lower melting point. The industrialscale test results showed that ferronickel powder was obtained with average nickel and total iron grades of 1.76 wt% and 86.46 wt%, respectively, which indicated the successful industrial-scale test of coreduction roasting. Thermodynamic analysis theoretically illustrated the feasibility of the co-reduction of low-grade laterite ore and RM. Increased roasting temperature promoted the reduction of iron oxide and nickel oxide.
