Abstract
The invention comprises a method of making rockwool or mineral wool fiber insulation. The method comprises melting a natural calcium-iron-aluminosilicate mineral from one or more of hyaloclastite, lava, scoria, volcanic glass, volcanic ash, or any other mineral of a basaltic or intermediate chemical composition and spinning the molten product into fibers. The fibers are optionally combined with CO2, a carbonation aid or a carbon dioxide sorbent microporous material.
Claims20
A method comprising:
- heating hyaloclastite to its melting point to form a fluid melt;
- and
- extruding the fluid melt to form a plurality of fibers comprising one or more of un-carbonated Ca, Mg, Na, K or Fe.
A method comprising:
- heating hyaloclastite to its melting point to form a fluid melt, wherein the hyaloclastite comprises one or more of uncarbonated CaO, MgO, Na2O, K20 or FeO;
- extruding the fluid melt to form a plurality of fibers;
- and
- combining the plurality of fibers with a carbonation aid, wherein the carbonation aid facilitates the conversion of one or more of CaO, MgO, Na2O, K20 or FeO to a carbonate or a CO3 containing mineral in the presence of CO2, wherein one or more of the carbonation aid or the hyaloclastite has carbon dioxide bound thereto at a concentration greater than its atmospheric concentration.
