Hi findinggems, Some information from the Nemaska Lithium website, that may be an answer to your question.
It appears that the company holds several patents, over the membrane electrolysis process, that they intend to use.
It does appear, that Galaxy may be intending to use a mixture of traditional evaporative pond, and alternative tech processes, in a bid to fast track production at SDV.
Some interesting reading on NMX ElectroChemical Plant.
Nemaska Lithium Inc. is a developing chemical company whose activities will be vertically integrated, from spodumene mining to the commercialization of high-purity lithium hydroxide and lithium carbonate.
These lithium salts are mainly destined for the fast-growing lithium-ion battery market, which is driven by the increasing demand for electric vehicles and energy storage worldwide. With its products and processes, the Corporation intends to facilitate access to green energy, for the benefit of humanity.
The Corporation will be operating the Whabouchi mine in Québec, Canada, one of the richest lithium spodumene deposits in the world, both in volume and grade.
The spodumene concentrate produced at the Whabouchi mine will be processed at the Shawinigan plant using a unique membrane electrolysis process for which the Corporation holds several patents.
Nemaska Lithium has released a Feasibility Study on the Whabouchi lithium mining project which encompasses a combined open pit lithium mine and underground lithium mine and concentrator located in the Eeyou Istchee James Bay Region of Quebec, Canada, near the Cree community of Nemaska. The goal is to become a leading supplier of lithium hydroxide and lithium carbonate to the emerging lithium battery market.
The electrochemical plant will be located in Shawinigan, QC. Nemaska Lithium announced in September 2015 the signing of an agreement in principle with the City of Shawinigan for the acquisition of part of the land and part of existing manufacturing facilities (Produits forestiers Résolu's former Laurentide plant) in Shawinigan.
This site will host both phase 1 and the commercial phase plants and has been selected for its excellent infrastructure. It is seviced by existing railways, natural gas, an important pool of skilled workers and a nearby port.
The electrochemical plant will be state of the art and will use Nemaska Lithium's proprietary process to convert the spodumene concentrate into the purest lithium hydroxide on the market. Proximity to the Hydro-Quebec network, as the plant will use close to 50 MW once in full operation, and access to the natural gas network were also deciding factors.
Nemaska Lithium - 2018 Feasibility Study
Both the Phase 1 plant and the commercial chemical plant will be built in Shawinigan, Quebec.
