Jiuwu High-tech Membrane Extraction Technology


Hisako Hi-Tech has obtained a number of patents in the lithium brine extraction industry, namely: "A Method and Device for Extracting Lithium Chloride Salt" (Patent No. 2013107314306), "An Extraction Device for Lithium Chloride Salt" (Patent No. 201320868761X), "A device for extracting battery-grade lithium from brine" (Patent No .: 201406044390), "A process and device for extracting battery-grade lithium from brine" (Patent No .: 2014105552130), "An adsorption method Method for Extracting Lithium in Salt Lake Brine "(Patent No .: 2014103532749)," A Device for Extracting Lithium from Salt Lake Brine with High Magnesium-Lithium Ratio "(Patent No .: 2017210342682), and also obtained the invention patent of the Qinghai Salt Lake Institute of the Chinese Academy of Sciences" Na The exclusive license of "Method for Separating Magnesium and Enriching Lithium from Salt Lake Brine by Filtration Method" (Patent No. 03108088.X), which is the basic patent for membrane method for lithium extraction.


Optional process route for salt lake / brine extraction of lithium


1. The "violent" lithium-raising route

This process is suitable for brines of various magnesium-lithium ratio systems. The technology is economical for high magnesium-lithium ratio brine systems;

Features:

  • High recovery rate;

  • Good selectivity and wide practicability; all kinds of magnesium-lithium ratios can basically be adsorbed;

  • Environmental protection, no three wastes; less impact on salt field balance;

  • The advantages of high magnesium and lithium over salt lake are very obvious;

  • The waste liquid after adsorption can be returned to the salt field to continue to extract potassium, sodium, etc.

  • Short construction period, can directly extract lithium in salt lake brine


2, membrane pharaoh halogen extraction of lithium

This process is suitable for a variety of old halogen systems with relatively low magnesium-lithium ratio (less than 50: 1), relatively high lithium concentration (at least 2g / L), and other monovalent ions and lithium ions that have relatively low first-comparison ratios. .

Features:

  • High water requirements;

  • High lithium concentration requirements;

  • Mg-Li ratio is lower;

  • High monovalent ion ratio required;

  • High quality lithium carbonate products;

  • The construction period is long, and it is necessary to build salt fields to raise potassium and sodium in the early stage;

  • Environmental protection, no three wastes.
