BioTeq Granted Two Patents for Mine Water Treatment
BioteQ's proprietary nickel sulphide precipitation process, US patent No. 8,747,678 B2, relates to processes to selectively remove nickel from mine impacted waters. BioteQ currently uses the process at its water treatment facility in northern Quebec.
The proprietary sulphate removal process, US patent No. 8,551,340 B2, relates to processes to selectively remove sulphate from hard water waste streams. This process has been used in various testing and piloting projects to date.
BioteQ's application PCT/CA2014/05096 is for its Selen-IX technology which can selectively remove selenium from mine impacted waters and potentially other industrial waste streams. This international filing provides BioteQ with protection for the technology in 148 countries throughout the world and follows the filing of the US provisional patent application in October 2013.
Since then, Selen-IX technology has been used in two pilot scale operations, first with a Canadian metals and mining company in 2013 and currently with another Canadian mining company.
