Claim 1:
2. A method of manufacturing a magnesium based hydrate composition, comprising:
selecting a magnesium containing silicate source;
subjecting the magnesium containing silicate source that is selected to acid wash, to produce an acid digested solution;
subjecting the acid digested solution to a base wash by adding a base solution to the acid digested solution to produce a magnesium salt solution and, during this step, removing silica, iron or other metals and minerals from the magnesium salt solution;
subjecting the magnesium salt solution to electrolysis to recover magnesium hydroxide;
mixing the magnesium hydroxide that is recovered with a solution containing NaOH and water to produce the magnesium based hydrate composition;
wherein said magnesium based hydrate composition comprises
60-90% by weight of magnesium hydroxide containing material;
1 to 10% by weight of said NaOH; and
greater than 5% of said water,
such that via said NaOH of said magnesium based hydrate composition, said magnesium based hydrate composition is configured to catalyze sequestration of carbon to said magnesium hydroxide containing material.
