Independent Claims | See all claims (31)

  1. 1. A method for producing micron- or sub-micron-sized mineral particles from mineral and mining shines or tailings to be used in a carbon dioxide sequestration reaction system, comprising classifying particles from silicate mineral mining slime or tailings thereby providing mineral particles of a size suitable for use in said carbon dioxide sequestration reaction system.
  2. 2-21. (canceled)
  3. 22. A method for sequestering carbon dioxide produced by a carbon dioxide source, comprising classifying silicate minerals from mining tailings or shines to obtain particles of a desired size; combining mineral particles from said classifying with water to form a slurry; and reacting metals from said particles in said slurry with carbon dioxide containing emissions from said carbon dioxide source to form mineral carbonates.
  4. 25. (canceled)
  5. 34. (canceled)
  6. 44. (canceled)
  7. 47. (canceled)
  8. 49. A method for sequestering carbon dioxide produced by a carbon dioxide source, comprising obtaining silicate mineral particles of a desired size classified from mining tailings or shines; combining said silicate mineral particles with water to form a slurry; and reacting said particles in said slurry with carbon dioxide containing emissions from said carbon dioxide source to form mineral carbonates.
