Abstract
The invention comprises a method of making lime, dolomitic lime, hydraulic cement such as portland cement clinker and co-products such as pozzolan, acids, alumina, silica and the like while producing reduced amounts of carbon dioxide. The method comprises combining hyaloclastite with a first acid to form a first salt, combining the first salt with a second acid to form a second salt and heating the second salt to form an oxide.
Claims19
A method comprising:
- combining hyaloclastite with a first acid to form a first salt;
- combining the first salt with a second acid to form a second salt;
- heating the second salt to form an oxide;
- and
- wherein the hyaloclastite is basaltic hyaloclastite or intermediate basaltic hyaloclastite, wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 500 um, wherein the hyaloclastite is approximately 5% to approximately 95% amorphous and wherein the hyaloclastite is approximately 5% to approximately 95% microcrystalline.
