Abstract. The production of nickel and cobalt from primary sources involves beneficiation, and hydrometallurgical and pyrometallurgical processing. Nickel is recovered from lateritic oxides either as ferronickel from saprolite ores or as an intermediate mixed sulfide or hydroxides from limonite ores. Sulfide ores are converted into matte.

Nickel ore refers to the naturally occurring rocks or minerals that contain significant amounts of nickel. Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white metal with a relatively high melting point and excellent corrosion resistance. Nickel is commonly found in the Earth's crust, but it is typically …

In 2019, nickel deficit in the market shrank to 42 kt (from 149 kt in 2018), driven primarily by an increased production of nickel pig iron in Indonesia and China (by 32%, or 228 kt) on the back of cheap supplies of high nickel content laterite ores. There were only marginal increases in the production of refined nickel (1%, or 11 kt) and its ...

Nickel is widely used in industrial processes and plays a crucial role in many applications. However, most of the nickel resource mainly exists as nickel oxide in laterite nickel ore with complex composition, resulting in difficulty in upgrading the nickel content using physical separation methods. In this study, high-grade ferronickel concentrates …

In this work, the selective reduction of lateritic nickel ore was carried out using sodium sulfate, sodium carbonate, and sodium chloride as additives. The 5 wt% of anthracite coal, which contains 60.35% of fixed carbon and 1.9% of sulfur, was used as a reductant. All raw materials were mixed homogenously prior to the pelletization process …

Ferronickel is made from nickeliferous laterite by means of pyrometallurgical processes. It usually contains iron and nickel, with a percentage ratio between 20:80-35:65. Ferronickel can be used in the production of stainless steel, low alloy steel, and other related alloys that contain approximately 65% nickel.

Ferronickel, currently obtained from oxidized nickel ores in various aggregates, contains from 5 to 20% of Ni. According to experiments, rich ferronickel ( …

Carbon can be oxidized from ferronickel, which lowers the content of carbon down to 0.02% without significant oxidation of nickel. Oxygen is injected into ladles or into small oxygen …

Kotzé [16] proposed the process of producing ferronickel from nickel oxide ores and dust particles by DC arc furnace technology. Guo [17] carried out ferronickel smelting experiment to investigate the selective reduction and melting-separation processes, and to analyze the influence parameters of metallization rate.

Laterite ore is one of the important sources of nickel (Ni). However, it is difficult to liberate Ni from ore structure during reduction roasting. This paper provided an effective way for a robust recovery of Ni from laterite ore by H2 reduction using sodium thiosulfate (Na2S2O3) as a promoter. . It was found that a Ni content of 9.97% and a Ni recovery of 99.24% …
