LEACHING METHOD OF LATERITE ORE USING AN IMPACT GRINDING EFFECT, CAPABLE OF LEACHING NI AND MG USING GRINDING ENERGY AND A LOW CONCENTRATION OF ACID

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.;COPYRIGHT KIPO 2011
