VANCOUVER, British Columbia, August 04, 2021 (GLOBE NEWSWIRE) – HUDSON RESOURCES INC. (“Hudson“or the”Company“) (TSX Venture Exchange” HUD “; OTC” HUDRF “) is pleased to announce the results of independent testing of the anorthosite at the White Mountain mine in Greenland. Testing, conducted in Norway, confirms that The anorthosite from the White Mountain mine gives very high leach recoveries with short leach times for the dissolution of aluminum and calcium This is the key first step in the production of an “Alumina” product. waste-free smelter-grade green ”work for the aluminum industry. This work confirms previous Hudson work completed at SGS Lakefield and ongoing test work undertaken at KPM in Kingston, Ontario (see NR2021-03) Hudson’s goal is to demonstrate an economical process to produce a “Green Alumina” product from anorthosite Hudson owns a 31.1% interest in the White Mountain anorthosite mine and the rights to acquire 100%.
The tests were carried out by the Institute for Energy Technology (IFE) in Norway as part of its AlSiCal project and were funded by the European Union (EU) Horizon 2020 research and innovation program as part of Grant 820911. For more information on IFE, please see https://ife.no/en/ and for more information on AlSiCal, please refer to: https: //www.alsical .eu /.
Hudson provided several anorthosite samples for testing, including a minus 250 micron product and coarse rock samples (+100 mm), ground and sieved down to 77-760 microns for testing. The IFE has determined that the identified samples submitted by Hudson were “of high quality” for the AlSiCal project. The main results are as follows:
- Aluminum and calcium are leached simultaneously
- Leaching between 87 and 97% by weight (percentage by weight) during the first two hours
- Leaching from 93 to 100% by weight in four hours
- The variability in the range is attributed to different particle sizes and / or the natural heterogeneity of the anorthosites
The results were confirmed by ICP-MS analysis and XRF analysis.
Tests on both samples showed what the IFE considered “rapid washout ” characteristics and a “high total dissolution yield (being at 100% the theoretical maximum dissolution yield calculated on the basis of the available analyzes) ”.
The objective of the AlSiCal project is to guarantee for the EU a sustainable process of production of alumina, silica and precipitated calcium carbonate by researching, developing and reducing the risks of revolutionary technologies targeting ZERO bauxite residues and ZERO emissions of CO2 during their co-production. Two leach tests were performed by the IFE, which included the following steps:
- Mixture of anorthosite with 20% by weight of hydrochloric acid (HCl) at 140 degrees C
- Cooling of the final reaction mixture
- Separation of liquid and solid fractions by centrifugation and decantation
- Washing of solid fractions and drying
Jim Cambon, President, said: “EU-funded testing conducted by IFE and AlSiCal independently confirms an efficient and straightforward leaching process of aluminum and calcium from White Mountain anorthosite. This represents a key step in the production of a waste-free “Green Alumina” product and offers a direct replacement for bauxite which creates nearly four tonnes of waste for every tonne of aluminum produced. Now is the time for the production of truly green aluminum in which anorthosite is a key solution.
In addition to its interest in mining the White Mountain anorthosite, Hudson owns 100% of the Sarfartoq rare earth elements (“REE”) project and the high-grade Nukittooq niobium-tantalum project located on the permit. exploration of Sarfartoq. The Sarfartoq REE project has an indicated and inferred resource 43-101 describing 35,000 tonnes of neodymium oxide and praseodymium oxide, the two key components of permanent magnets that are behind the green revolution. There is significant potential for expanding this REE resource, while the Nukittooq project has some of the highest niobium assays in the industry (see NR2020-15).
