Ionic Rare Earth Mineral Extraction Equipment

Construction unit: A rare earth company in Fujian

Production time: 2021

Main machine selection: CWL650-M Centrifugal Extractor

Mixed flux: 50m³/h

Project Overview

The ionic rare earth ore extraction system uses CWL-650M centrifugal extractor. The centrifugal extraction technology equipment combines the advanced equipment of the CWL-M series centrifugal extractor with a unique process to solve environmental problems and radioactive elements, while achieving higher extraction efficiency.

Background of the project

Previously, Zhengzhou TIEI Extraction cooperated with Beijing Nonferrous Metals Research Institute to establish a rare earth concentration production line at Chinalco Guangxi Rare Earth Mine.

Process Introduction

This production line adopts extraction technology, and the main machine is Zhengzhou TIEI Extraction CWL650-M Centrifugal Extractor. The whole production process does not produce ammonia nitrogen wastewater and radioactive waste residue. It not only solves the technical problems such as low resource recycling rate in the process of leaching, enrichment, separation and purification of ionic rare earth minerals, and serious waste pollution. And it also greatly reduces equipment operating costs and labor output costs, effectively promoting the further development of rare earth green development technology.

CWL650-M Centrifugal Extractor

  1. The drum of the CWL series centrifugal extractor adopts a top-suspension structure. There are no bottom bearings and mechanical seals in the processing area, and there is no risk of leakage. This solves the problems of frequent failures and short service life of centrifugal extractors.
  2. Lower power consumption. Under the same processing capacity, its power consumption is 1/10-1/3 of the traditional annular structure centrifugal extractor.
  3. Thevariety of mixing structures are available, suitable for systems that are easy to emulsify. Accept customization of different extraction systems.
  4. Large processing capacity and small floor space. The world’s first industrial application of large-throughput centrifugal extraction machine.
