title = "Quantitative leaching of nickel from jarosite using sulphuric acid",
abstract = "This paper deals with the extraction of nickel from jarosite precipitates. Nickel loss to these precipitates is mainly by entrainment and coprecipitation. Nickel is hazardous to the environment. In this study, an attempt has been made to extract nickel entrained in jarosite precipitates produced at Implats Base Metal Refineries. The leaching efficiency of nickel was 59% at 30°C. The acid concentration of 0.5 - 1M, pulp density of 10%, leaching time of 21/2 hours was found to be optimum. High concentrations of acid and high temperatures could break the jarosite structure and release more Fe into the solution which will adversely affect the following precipitation process. The reaction is diffusion independent.",
