From 2021 to 2022, Qinghai Jingyuan Zangjin Salt Lake Co., Ltd., a wholly-owned subsidiary of Xi'an Gold-In Membrane Environmental Protection Technology Co., Ltd., completed the filing of the "Brine Refining Project" at the Department of Industry and Information Technology, Qinghai Province. The project invested 116.35 million yuan, built 3.3 million tons/year of refining brine devices, and built supporting softening workshops, laboratories, dispensing rooms and other public and auxiliary facilities. As of October 2022, the production line has been debugged and started stable production.

Technical Advantage of the Project 

1、The self-developed ion exchange adsorption process for refining salt lake brine is of great significance for the deep impurity removal of salt lake brine;

2、Regulate the adsorbent and operating conditions to make the adsorbent have a good selectivity for lithium ion, which is more conducive to the purification of Magnesium chloride solution. This process has stable adsorption elution performance, high efficiency, and good quality of lithium salt by-products;

3、Simple process, low environmental pollution, and the ability to maximize the utilization of brine resources.

Cooperating Project

1、Qarhan Salt Lake Technology Project: Pilot plant of 2 t/d Lithium carbonate (industrial grade) base station project;

2、Lanke Lithium Project: Industrial level research and development project for efficient recovery of lithium mother liquor.
