BQE Water to provide plant operations services for Minto Mine water treatment plant

BQE Water has entered into an Operating Services Agreement with Minto Metals Corp to provide plant operations services for an existing water treatment plant at Minto Mine, some 240 km northwest of Whitehorse, Yukon, through to 2024.

Under the agreement, BQE Water will be responsible for clean water production at the Canadian mine where the final effluent must meet stringent requirements not only for metals but ammonia, nitrite and nitrate to protect the aquatic life in the receiving environment. Included in the operations services provided by BQE Water will be on-site technical supervision, coordination with Minto’s environmental and metallurgical team to maximise the volume of water discharged into the environment, operator training, and on-site and off-site engineering support.

BQE Water’s compensation will be composed of a base monthly fee and a supplemental fee for the volume of water treated that meets discharge specifications. It is estimated the plant will treat and discharge 400,000 cu.m of mine water for the remainder of the year and approximately 750,000-1,000,000 cu.m of mine water in each subsequent year of the current contract.

“We are highly appreciative of the responsiveness and technical proficiency provided by BQE Water to address the concerns we had with our water treatment plant,” Loralee Johnstone, the VP of Environment and Social Governance for the mine, said. “The transition to their operations has been systematic and transparent, with the resulting operational work surpassing our expectations.”

David Kratochvil, BQE Water’s President & CEO added: “We value the opportunity to help Minto achieve its environmental and social governance goals. We also look forward to collaborating with the Selkirk First Nation to achieve sustainable and transparent water management at the mine.”

As part of its role at Minto, BQE Water has engaged in discussions with the mine and the Selkirk First Nation about creating an active role for the local community to participate in clean water production at the site to ensure the continued protection of land and water for countless generations in the future.

The Minto mine has been in operation since 2007 with underground mining commencing in 2014. The current mine operations are based on underground mining, a process plant to produce high-grade copper, gold and silver concentrate and all supporting infrastructure associated with a remote location in Yukon.

Clean TeQ Water to test BIONEX water treatment solution in Inner Mongolia

Clean TeQ Water says it has been awarded a contract to design, procure, deliver and install a BIONEX water treatment plant at a coal mine in Inner Mongolia, China.

Clean TeQ Managing Director, Sam Riggall, said: “We have persisted for a long time to make inroads into the very large Chinese water treatment market. As we move towards the proposed demerger of our water business later this year, it is pleasing to see that we have achieved some initial success in that important market as we continue to make good progress on our goal of growing revenues.”

The BIONEX solution is a combination of the company’s Continuous Ionic Filtration and BIOCLENS (bacteria encapsulated in a protective PVA lens) technologies, which, the company says, has been demonstrated to be highly effective for removal of nitrate from wastewater.

“This market is growing rapidly due to increasingly strict regulation and increasing safety concerns over the disposal of waste waters with even very low levels of nitrate,” CleanTeq said. “Nitrate removal from water effluent is a significant challenge throughout China.”

The plant has been designed to treat and remove nitrate from 12,000 cu.m /d of coal mine in-pit ground water to below 1 parts per million in order to comply with local regulations governing the disposal of mine water.

The contract, which is valued at approximately A$2 million ($1.55 million), has been awarded to the company’s wholly owned Beijing-based subsidiary by Beijing Beihua Zhongqing Environment Engineering Technology Co Ltd. (BHZQ). BHZQ is a subsidiary of Beijing Enterprise Water Group (BEWG).

BEWG is a diversified water company focused on operating water assets throughout China. It is also one of the largest water treatment companies in Asia, CleanTeQ said, adding that BHZQ had expressed an interest in ongoing cooperation once this first BIONEX plant is successfully commissioned.

Once completed, this application will be the company’s first ever large-scale application of BIONEX in China.
