Mag One’s proprietary technology is to be used to process the 22% Mg serpentinite tailings in Quebec for a variety of commercially viable uses and products.
The initial emphasis will be on producing high-value, high-purity MgO and Mg(OH)2, in excess of 99%. For it is this ultrapure MgO that is the precursor and fundamental element for the production of Mg metal.
There are a range of uses for both products and Mag One has overcome the traditional difficulty of economically achieving 99% purity. Ultrapure grade MgO is used to produce Mg metal and specialty needs such as smoke suppressants, fire-fighting agents and for refractory applications. Lower grades used in agricultural, chemical and environmental applications such as in the manufacturing of Mg-based wallboards (*see Mag One’s Project I.), fertilizers, de-icing agents, milk of magnesia, etc.
Mg(OH)2 is used in both plastic, rubber and roofing products as a flame retardant. In environmental protection it is used as an agent in acid wastewater treatment, as a heavy metal removal agent, for antacids and laxatives as well as gymnastics chalk.
Mag One’s initial processing plant (located near the Company’s tailings site) is expected to have a capacity of 10,000 tonnes/annum of MgO and 10,000 tonnes/annum Mg(OH)2 with a CAPEX of $6 Million.
Target date for start of production, February 2017.
