[{"type":"text","content":"Scandium International Receives Two Patent Grants Relating to Scandium Recovery and Scandium Master Alloy ManufacturingRENO, NV / ACCESSWIRE / May 20, 2021 / Scandium International Mining Corp. (TSX:SCY) (\"Scandium International\" or the \"Company\") received notice of two separate patent grants from the US Patent Office in late April 2021, pertaining to work done by the Company to reserve rights in the recovery of scandium from copper raffinate solutions via ion exchange techniques, and to reserve rights in the manufacture of aluminum-scandium master alloys via these defined techniques. Both of these patent grants are directly applicable to processes and projects the Company is currently engaged in, with the intent to produce scandium products for use in both aluminum alloys and other technical applications.HIGHLIGHTS - \"Extraction of Scandium Values from Copper Leach Solutions,\" Patent Number 10,988,828, granted April 27, 2021.Defines methods for recovering scandium from copper mine acidic solutions.Tailored specifically to oxide copper heap leach solvent extraction (SX) raffinates.Specifically employs ion-exchange technologies, pre or post copper recovery.HIGHLIGHTS - \"Scandium Master Alloy Production.\"Patent Number 10,988,830, granted April 27, 2021.Defines methods for manufacturing aluminum-scandium master alloy (2%).Identifies a two-flux system, containing a fluoride and an alkali metal chloride.Allows for a rare earth element oxide addition, if desired. Further allows for other critical metal additions to master alloys, where those are demanded as metal additions in the final aluminum alloy.George Putnam, CEO of Scandium International Mining Corp. commented:\"These patent grants add to our suite of patent protections, designed to give SCY a competitive advantage in critical metals recovery. The scandium ion exchange recovery patent grant meets a technical milestone for recovery of scandium from copper solutions. The unique master alloy production methods grant can be applied to enhance our scandium product offering for any of our potential scandium-source projects.\"DISCUSSION:The Company announced in May 2020 that it was immediately focusing on critical metals recovery (\"CMR\") from acid leachate solutions common to oxide copper recovery plants, initially in the USA. Two provisional patent applications were in plac...
