Abstract
Ferronickel slag is a hazardous industrial waste containing a relatively high amount of chromium , which poses a great potential threat to the environment. It is of great significance to recover chromium from the slag for both economic and environmental benefits. In this study, recovery of chromium from ferronickel slag via alkaline roasting followed by water leaching was investigated, with an emphasis on the effect of roasting atmosphere on the phase transformation of ferronickel slag during the alkaline roasting process.
