Mar 10, 2021 Two-thirds of the global nickel output can be attributed to the rotary kiln-electric furnace process. Due to the high contents of MgO and SiO 2 in laterite, a high temperature (1600 C) and corresponding energy (approximately 14 GJ/t-ferronickel) are required during the electric furnace smelting. This work verifies the feasibility of decreasing the smelting temperature by controlling the

Produksi NPI dan FeNi dihasilkan oleh smelter Blast Furnace (BF) dan Rotary Kiln Electric Furnace (RKEF). Sampai tahun 2020, sebagian besar pengolahan biji nikel di Indonesia berada pada jalur untuk memproduksi NPI dan FeNi, bukan pada jalur untuk baterai. Untuk jalur baterai ini diperlukan teknologi hydro metallurgy yang sangat canggih dan
