Demystifying tailings

Complete destruction of chrysotile fibres

Alliance Magnesium’s technology eliminates all residual traces of chrysotile fibres as soon as they enter the production process. No fibre concentration is present in the plant as of the leaching stage. Beyond that point, the fibre is completely destroyed. To support this finding, tests were performed in an independent laboratory by a chemist using samples of Alliance Magnesium serpentine, the results of which were then analyzed by an accredited external laboratory.

No trace of asbestos in the finished product

Canadian federal law strictly prohibits the manufacture, sale, marketing and export of asbestos. Alliance Magnesium has a zero-tolerance policy: its process completely destroys the fibres, creating an entirely asbestos-free product.

Free fibre content of the deposits

The serpentine has less than 2% free fibre content, based on analyses of samples taken from the tailings pile for the NI 43-101 and Geocon studies. These soils contain chrysotile, a type of asbestos that releases very low concentrations of fibres (Institut de Recherche Robert-Sauvé en santé et en sécurité du travail IRSST, Study and Research Report). The issue to be evaluated is free fibres with dispersion potential. The mass fibre, bound to the rock, must not be inhaled.

No compromise on health and safety

The company has always been concerned about the safe use of raw materials for the public and workers. Modelling analyses show no potential for dispersion beyond detectable standards. Nevertheless, Alliance Magnesium planned for the implementation of an asbestos site work management program as well as mitigation measures where necessary.

The Bape believes that thea recovery of asbestos-financed tailings through the extraction of metals and raw materials subscribes to the following principles of sustainable development: environmentalprotection/healthand quality of life/economic/efficiency/protection/andresponsible consumption. The recovery of tailings could be a tangible application to a circular economy that encourages a rethinking of production and consumption models.

Preparation of the raw material

Dehydration and drying

No trace of asbestos in the finished product.



It’s important to note that Alliance Magnesium does not work with asbestos. It uses the waste generated from industrial fibre extraction. The raw material used to produce magnesium has therefore already been extracted, processed, crushed, milled, etc., since the fibre was removed for sale.
