E3 metals is closer to extracting lithium from oilfield brine

E3 metal company proprietary lithium extraction technology of preliminary metallurgical test produced up to 1206 mg per litre of lithium concentrate, which concentration factor is 16 times. This company is in Calgary.

The process also successfully to key metal impurity decreased by 99%, at the same time show lithium recovery rate is as high as 81%.

Test done by the university of alberta, and by the CIMIC group of mineral processing company Sedgman Canada Limited independent review.

E3MetalsAlbertaLithium project for the development of a big step forward, E3Metals ChrisDoornbos chief executive said in a statement.

"To develop a simple and effective brine concentration process, significantly reduce the impurity, we set out to verify the company large alberta oil lithium resources in the economic and technical feasibility. With the continuous optimization of adsorbent, our goal is to achieve higher recovery rate and higher concentration multiple. We are actively developing the next step of work, in order to promote alberta oil lithium extraction technology of the project, "he said.

Project area in western Exshaw E3 metal company six on rich lithium whose formation water (brine) enrichment technology of small scale metallurgical test. In less than three hours to complete the whole process of enrichment. The company is expected in the next four weeks to submit relevant NI43-101 technical report.

According to the results, said E3Metals will strive to optimize and expand its enrichment technology, to further improve lithium concentration and recovery performance. Enrichment technology will become the company in the production of lithium two main extraction step the first step.

The company in collaboration with the university of alberta, is now in the submitted a provisional patent to protect intellectual property rights related to its enrichment technology.

So far, E3Metals have identified in the area of the three resources 6.7 million tons of lithium carbonate equivalent (LCE) integrated resources, including alberta holdings to 34% of the permit.

With the high porosity and permeability, whose formation has been shown to transport a large number of hot brine (70 to 100 degrees Celsius). The company said, with a wide range of oil and gas well infrastructure - including processing, production base and piping - and mature regulatory system, alberta lithium for oil development have a lot of appeal.

Six test produced lithium recovery, lithium concentration and reduce critical (impurities) ion concentration of a series of results. The highest lithium recovery increased from 66% to 81%, while the concentration of lithium ranging from 13 to 16 times. Key to significantly reduce the impurity, with an average of more than 99%.

E3Metals said that although the project is still in the concept level, but the concentration may be further processed into lithium carbonate and/or lithium hydroxide. Its further development of ion exchange technology will continue to be in A UU optimum adsorbent synthesis and extraction tests. The company said the goal is through the process to achieve higher recovery rate and the increase of lithium enrichment factor, while maintaining a high level of impurities.
