Cotec Purchases Commercial Scale Salter Cyclone Multi-Gravity-Separator Unit to be Located at Corem Québec, Canada
CoTec Holdings (OTCQB:CTHCF, TSXV:CTH) purchased a commercial-scale Salter Cyclone Multi-Gravity-Separator (MGS) to be installed at Corem testing laboratory in Québec, Canada, announced October 28, 2025.
The MGS targets recovery and upgrading of fine and ultra-fine mineral particles, enabling high-grade concentrates from low-grade tailings and middlings. CoTec says the unit will support the Lac Jeannine Feasibility Study with BBA for additional iron recovery and accelerate scale-up from lab to commercial data for engineering and valuation. The company notes prior February 2025 exclusivity and collaboration with Salter to apply MGS for iron and manganese recovery.

VANCOUVER, BRITISH COLUMBIA / ACCESS Newswire / October 28, 2025 / CoTec Holdings Corp. (TSXV:CTH)(OTCQB:CTHCF) ("CoTec" or the "Company") is pleased to announce the purchase of its first commercial scale multi-gravity-separator ("MGS") from Salter Cyclone Limited ("Salter").
The MGS provides a highly effective "recovery and upgrading of mineral values" contained in fine and ultra-fine particles. It is unique in enabling the production of high-grade concentrates at high recovery from low-grade tailings and middling streams which differentiates it from other gravity recovery technology which focuses on either recovery or grade. The MGS has historically proven itself on minerals such as tin, tungsten and chrome, however CoTec is aiming to use the technology to unlock value from tailings streams in other sectors such as iron and copper.
The MGS will be based at Corem's testing laboratory in Québec Canada. Having the commercial scale unit based at Corem will allow CoTec to assess tailings retreatment opportunities in a compressed timeframe with test results coming from an internationally respected mineral processing organisation. The MGS machine will support the recently announced Lac Jeannine Feasibility Study with BBA, for the recovery of additional iron ore from our Iron Tailings reclamation Project in Québec, Canada Project i .
Julian Treger, CEO of CoTec commented : "The purchase of the MGS is another exciting step forward in achieving CoTec's corporate strategy of applying technology to recover minerals from material classified as waste. Test work to date on Lac Jeannine's -75µm iron tailings material has proven that high grade concentrates at economically viable recoveries are achievable, and the Feasibility Study will build on this work and expand into other minerals such as copper, lead and zinc. A commercial scale MGS based at Corem provides CoTec with the ability to move rapidly from lab scale testing to commercial scale data gathering for engineering design and economic valuation. This ability to assess opportunities in a compressed timeframe allows for efficient capital deployment and the ability to bring operations online far quicker than current industry standards. We continue to work closely with Salter as this exciting technology develops".
MGS Technology
In February 2025, CoTec announced the signing of a binding long-term exclusivity and collaboration agreement with Salter for the application of its Multi-Gravity Separators (MGS) technology for the recovery of iron ore and manganese from both primary mining and tailings material ii . Salter's MGS technology was originally developed in the 1980s by Richard Mozley and has been in operation for many years applied to the recovery of valuable metal minerals (tin, chromium, copper, zinc etc.). Its application to bulk commodities such as iron and manganese has been limited. As part of the collaboration CoTec and Salter will actively collaborate on an asset-by-asset basis to apply the technology to identified assets.
