Anson Resources Limited (ASX: ASN), a mineral explorer and mineral resource project developer, provided an update on its Li Pilot Plant process design and engineering, on 9th May 2019. The planned pilot plant is at the company’s Paradox Brine Project near Utah in the United States of America.
As per the company, it completed the hatch engineering, which marked the completion of engineering design of the brine pre-treatment. The lithium carbonation processes of the pilot plant along with Lilac Solutions is nearing completion of the designing and construction of the lithium extraction process of the planned industrial-scale in-field pilot plant.
Following the completion of testing performed by Hazen Research, the company completed an assessment, which includes the extraction of other chemical products into the pilot plant flow sheet. The update flow sheet of the company looks like:
Upon completion of the test work, the company short-listed suppliers of the pre-treatment sections.
Ion Exchange Extraction:
Lilac Solutions (Lilac) is expected to complete the design and construction of the lithium extraction system using ion exchange in the second quarter (Q2). However, the design and construction will not contain any upstream nanofiltration, evaporation ponds, or any other concentrating processes. Anson mentioned that the minimal energy and water input of the pilot-scale, ion exchange lithium extraction system, will be accommodated using a waste-water RO (Reverse Osmosis) mini-plant and simple gas-powered generators.
As per the company, Lilac is also working on a design of an ion-exchange extraction system, which it will demonstrate on site to de-risk the ion-exchange technology process block of the company’s flowsheet. Anson mentioned that Lilac previously recovered more than 80% of lithium from the brine in Paradox Basin, with a low concentration of contaminants.
Anson commenced the detailed design and engineering stage and appointed Tom Currin of Southwest Technologies to design, build and provide consulting services for the carbonation process of the pilot lithium plant, which is designed to convert lithium rich eluate into a battery quality carbonate product.
As per the company, it intends to produce a 20kg sample of micronized, dried lithium carbonate product off-site. The sample products will be following a high standard and strict battery quality specification, which is provided to the company by a potential off-taker, who plans to use it further for cathode material construction. As per the company’s estimation, the quality standards on other lithium carbonate products are quite loose as compared to the standard demanded by the potential off-taker. And, if the company meets this standard, its’ lithium carbonate will be appropriate for use by other high prospective consumers as well.
Continuing on the 6th May 2019 announcement made by Anson Resources Limited, today the company mentioned that post the discussion with the ASX, it retracts the statement made concerning the pilot plant trail production exceeding 100 tonnes a year.
The company mentioned that the statement about the production volume does not comply with the ASX requirement, as the company, not compiled the information required to disclose the trial production following the JORC Code 2012.
Anson currently opened a Security Purchase Plan for eligible shareholders and is in discussion with parties, which expressed interest, to fund the lithium pilot plant.
The share of the company was trading at A$0.059 (as on 9th May 2019, AEST: 03:20 PM), up by 1.724% as compared to its previous close.
