ClearBakk recently attended the Water In Mining Global Summit in Vancouver. The summit focuses on water stewardship in the mining industry. We’ve outlined a few key takeaways below, and how ClearBakk can assist mining companies in this space.
- The regulatory space is rapidly changing due to global climate change. Regulators prefer tried and true methods over untested methods, but are willing to work with companies on pilot projects.
- Did you know that 80+ Percent of new mines are in water scarce areas? New mines are required to have extensive water efficiency and integrated planning from Day 1.
- The large mining companies commit to reducing fresh water usage (2015-2018 baseline) by 30-50% by 2030. Reducing freshwater usage can be accomplished by capturing and recycling water used by the processing plant, capturing seepage from tailings to get recycled, using other dust suppression methods, and desalinating sea water to name a few.
- Some mine sites have positive water balance, rather than negative water balance, which puts them in a unique situation. Stringent regulations (particularly salt and other contaminants) regarding discharge back to the environment is still proving tough for mining sites.
- Building trust is extremely important. Many mining companies are working with their local and Indigenous communities to rebuild trust. Some mining companies have extensive integration within Indigenous communities and involve members on decision-making as well as mining operations.
- While legacy mines are a financial and environmental liability, a few companies are exploring tailings re-mining to reprocess the tailings to recover valuable metals. Improvements in technology has made this financially viable. There are around 8,500 active, inactive and closed tailings storage facilities worldwide, with a collective footprint of 280 billion metric tonnes, and a value of $3.4 trillion in unmined metals. ClearBakk has extensive knowledge with dewatering and filtration, both of which are key to the re-mining of legacy tailings.
ClearBakk, along with the support of our parent company ALSYS can help you achieve your water reuse / tailings re-mining goals with a complete solution backed by our ceramic membranes. Whether it's designing a pilot plant or complete detailed design, we are available every step of your journey.
