Direct Lithium Extraction (DLE)

Sunresin is the major DLE lithium sorbent producer in China which mainly used for extraction lithium from salar brine and geothermal brine etc with high efficiency.

Besides DLE sorbents,Sunresin is the solution provider which supply the whole EPC solution from brine to finished product(Lithium carbonate or lithium chloride )

Sunresin could build and deliver the plant including design, equipments, sorbents, installation guidance, pilot running and training etc.
Generally saying, we supplied the whole lithium plant which ready to use.

Till 31th March, 2022, sunresin took 9 commercial DLE projects. (3 installed+1 installing+5 new projects)
For all the nine contracts received, it could contribute a total capacity of 73,000 tons of lithium carbonate and lithium hydroxide

For other lithium sources( spodumene, clay and lapidolite etc), sunresin was mainly involving in impurities removing jobs like Ca, Boron removal etc.

Below is the overview of sunresin salar brine lithium projects till 31th March, 2022

New projects received in 2022
Evebattery	10000tpa EPC plant	Contract newly received in 4th Jan,2022
Tibet National Energy	10000tpa EPC plant	Contract newly received on 14th Jan, 2022
Qinghai Chaidamu Xinghua Lithium	5000tpa DLE sorbent and resin equipment	Contract received in Jan, 2022
Tibet summit(Argentina site)	25000tpa DLE sorbent and resin equipment	Contract received on 21th Feb, 2022
Sanda (Evebattery project)	5000tpa EPC plant	Contract newly received in 4th Jan,2022

Finished project
Zangge Lithium	10000tpa lithium carbonate	Performance accepted, all payment has been done
Qinghai Jintai Lithium	3000tpa EPC plant	Performance accepted, all payment has been done
Minmetals	2000tpa lithium carbonate	Performance accepted, all payment has been done

Project under going
Qinghai Jintai Lithium	4000tpa EPC plant	Repeated expansion project, under preparing in sunresin plant
Minmetals	4000tpa lithium carbonate	Delivered to site already and now under installation
Qinghai Salt lake BYD Resources(Joint venture)	600tpa lithium carbonate（pilot plant）	Delivered to site already and now under installation

Item	Scope	Remarks
1)	Process balance and integration from the whole plant	including adsorption phase, Membrane phase, lithium precipitation etc, many small details matters
2)	Proven process which after years of optimization	means no project risks and super fast delivery
3)	Li sorbent with very low loss	Normally sunresin Li sorbent was not taken as consumable product due to the very low loss
4)	No PH adjustment for feeding brine and using purified water for regeneration	Eco friendly and easily adapt to any environment sensitive sites
5)	Massive production capacity for sorbent with quick lead time and competitive costing	Sunresin used same sorbent plants for different customers, so average cost is lower due to high workload
6)	SMB system which could greatly reduce sorbent quantity	Reduce the cost quite a lot, also much smaller system compared with fixed bed
7)	Ca removal system	Proven process with around 20 references
8)	Boron removal system with SMB design	Proven process with around 6 references
9)	Li/Na separation resin unit(unique in market), which could increase overall yield of plant for extra 10%	Proven process with around 2 references

We summary sunresin strength for Li with details as below:
Generally sunresin has been trying to optimizing the performance from overall project for many years:

For Ca, Mg and boron removal(impurity polishing), sunresin also dominated the market in China.
