System for preparing new energy ni—co—mn raw material from laterite nickel ore

Abstract

The present disclosure discloses a system for preparing new energy Ni—Co—Mn raw material from laterite nickel Ore. The system includes a raw auxiliary material supply module, a leaching reaction module, a neutralization and purification module, a neutralization and purification module, a Ni—Co—Mn mixed hydroxide synthesis module, a valuable metal recovery module, a crystal manufacturing module, a ternary precursor manufacturing module, and a ternary positive material manufacturing module. The present disclosure overcomes the defects of prior art and process, and is a green technology and process for simultaneous extraction of nickel, cobalt and manganese from low-grade laterite nickel ore, which not only realizes simultaneous and efficient extraction of nickel, cobalt and manganese, but also adopts energy-saving and emission reduction green technology and clean production technology to effectively recycle and safely dispose of waste water, waste residue and waste gas.
