AI Technical Summary
Existing nickel-iron extraction processes suffer from low iron utilization, high energy consumption, and severe environmental pollution, making it difficult to achieve high-value utilization of nickel-iron.
A method combining micro-sulfurization smelting and oxidative acid leaching was adopted. Micro-sulfurization smelting was carried out by mixing nickel-iron, sulfiding agent and slag-forming agent, followed by crushing, oxidative acid leaching, and finally roasting to separate nickel and iron, so as to prepare high-purity nickel sulfate and iron phosphate.
This technology enables efficient separation of nickel and iron, reduces the difficulty of nickel-iron processing, decreases energy consumption, makes production more environmentally friendly, provides a high-value utilization pathway, and supports the development of the new energy industry.
