Abstract
In recent years, alternative treatment processes of nickel low-grade ores have been studied for nickel mining. The present work intends to study the precipitation of metals such as nickel, aluminum, cobalt, iron, zinc and copper from liquor obtained in the atmospheric leaching of a limonite nickel waste. Initially, synthetic solutions were prepared to simulate the sulfuric leach liquor. The iron in the first solution was found in the form of ferrous ions (Fe+2), while in the second solution was found as ferric ions (Fe+3). Precipitation tests were carried at 25ºC and pH was varied with KOH additions. Metal concentration in aqueous and solid samples were analyzed by energy-dispersive X-ray (EDX) and a scanning by electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDS), respectively. Around 100% of iron, 60% of cobalt and 10% of copper were precipitated at pH 3,0 from the solution with ferric ions, while in the solution with ferrous ions, the highest metal precipitation were achieved at pH 5,5.
