Abstract
A method and apparatus for manufacturing ceramic microspheres from industrial slag. The microspheres have a particle size of about 38 microns to about 150 microns. The microspheres are used to create a cement slurry having a density of at least about 11 lbs/g. The resultant cement slurry may then be used to treat subterranean wells.

A method for manufacturing ceramic microspheres comprising the steps of:
- obtaining industrial slag;
- manufacturing microspheres from the industrial slag, wherein the microspheres have a particle size of about 38 microns to about 150 microns;
- and,
- using the microspheres to make a cement slurry, wherein the cement slurry has a density of at least about 11 lbs/g.
A method for treating subterranean wells comprising the steps of:
- obtaining industrial slag;
- manufacturing microspheres from the industrial slag, wherein the microspheres have a particle size of about 38 microns to about 150 microns;
- using the microspheres to make a cement slurry, wherein the cement slurry has a density of at least about 11 lbs/g, and;
- deploying the cement slurry into a subterranean well.
An apparatus for the manufacturing of ceramic microspheres from industrial slag comprising a vibration feeder, a glass bench burner, a first collection chamber, and a second collection chamber.
