New Energy Services Lithium extraction from salt lakes

Technical introduction

The company is committed to the research and development of lithium extraction technology
from multiple types of salt lakes and lithium-containing brine, and is in the leading position in the
industry in lithium adsorption materials, membrane separation technology, lithium extraction
process development and engineering of different types of salt lakes, and is one of the very few
Lithium Extraction from Salt Lakes domestic service providers that have mastered the core materials, process technology,
commissioning, installation and operation of lithium extraction with "adsorption + membrane"
Photovoltaic Materials separation and coupling. At present, the company can provide a variety of economically beneficial
product routes for various types of lithium-containing solutions, such as lithium chloride (low
potassium) refined products, LiOH products, Li2CO3 products, etc.
