PROCESS FOR LEACHING FROM LATERITE USING IMPACT-GRINDING EFFECT

摘要

PURPOSE: A leaching method of laterite ore using an impact grinding effect is provided to leach Ni and Mg using a low concentration of acid by exposing Ni from the crystal of laterite ore by physically breaking the crystal of the laterite ore. CONSTITUTION: A leaching method of laterite ore using an impact grinding effect comprises next steps. After ore is broken into particles, which are able to be put into a grinder using a jaw crusher and a cone crusher, the particles are put into a mill and are ground for a given time. The ground particles are put into acid fluid, are stirred with it and then are leached.
