The test work consisted of the oxidation of the brine using chlorine gas to convert the dissolved bromide ions into bromine liquid, which was successful.
Stage II pilot plant test work will now commence at De Dietrich premises in Germany later this month.
The pilot plant for this test work has already been constructed and minor modifications will be made to it after the review of this test work.
Pilot plant to use Kubierschky Process
The pilot plant will use the well-known and understood Kubierschky Process for the extraction and recovery of bromine from Anson’s Paradox brine.
The results of the pilot plant test work are expected in December and will include capex and opex estimates.
This data will be incorporated into the preliminary economic assessment (PEA) or pre-feasibility study (PFS) that Anson plans to commence before the end of the year.
A sample will also be produced for potential customers
A bromine product sample will also be produced as part of the test work.
Anson intends to offer this sample to potential investors and offtake partners for their consideration.
Bromine is one of the multiple products Anson intends to extract from the brine located within the Paradox Project as per its multiple mineral and revenue-stream strategy.
Bromine one of six products to be produced
A recently updated flowsheet was designed to produce six products: bromine, lithium hydroxide, lithium carbonate, chlorine, hydrogen gas and hydrochloric acid.
The latter three products will be used in the production process thereby reducing costs which would otherwise be incurred.
The chlorine, for example, will be fed into the bromine extraction process negating the need to purchase chlorine as part of the bromine production process.
