Processing of oxidized nickel ores using sintering, roasting
2022年5月15日 Based on the data obtained within this work, we can conclude that the leaching of nickel from native ore with a solution of sulfuric acid does not lead to its higher recovery. To intensify the process of converting nickel into solution, it is necessary to apply intermediate operations, including low-temperature sulfation, drying, and roasting.
