SUOYI Rare Earth Manufacturing Plant Introduction

SUOYI Rare Earth Manufacturing Plant Introduction
The Rare Earth Manufacturing Plant focuses on the extraction, separation and processing of rare earth elements. Scandium (Sc), yttrium (Y), lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb) and lutetium (Lu) Rare earth elements include 16 chemical elements, which are divided into two categories: light rare earth and heavy rare earth. These elements are crucial in modern technology and are widely used in electronics, energy, medical, military and other fields.

Main processes:
1. Ore mining: extracting rare earth elements from rare earth ores.
2. Ore processing: converting ore into powder suitable for chemical processing through steps such as crushing and grinding.
3. Extraction and separation: separating rare earth elements using solvent extraction, ion exchange and other technologies.
4. Refining and purification: further purify rare earth elements to meet industrial standards.
5. Product manufacturing: process purified rare earth elements into oxides, metals, alloys and other products.
