1. A process for converting Coal Ash and EAFD into a feedstock comprising: a. preparing a mixture of Coal Ash and EAFD;b. adding cullet and an additive to form a blend;c. melting the blend at a controlled temperature and time in an oxidizing atmosphere to create the feedstock, the feedstock comprisi
1. A process for converting Coal Ash and EAFD into a feedstock comprising: a. preparing a mixture of Coal Ash and EAFD;b. adding cullet and an additive to form a blend;c. melting the blend at a controlled temperature and time in an oxidizing atmosphere to create the feedstock, the feedstock comprising at least one spinel or metasilicate;d. processing the feedstock by grinding or crushing. 2. The process of claim 1 wherein the blend comprises about 90% to about 30% Coal Ash, up to about 50% EAFD, about 30% to about 10% of cullet and a trace of additive. 3. The process of claim 1 wherein the blend comprises about 95% to about 30% Coal Ash, up to about 50% EAFD, about 40% to about 5% of cullet and up to about 15% of additive. 4. The process of claim 1 wherein the additive is a crystallization catalyst that improves at least one of fracture, friability and toughness of the feedstock. 5. The process of claim 4 wherein the crystallization catalyst is a recycled abrasive. 6. The process of claim 1 wherein the additive is at least one of titanium dioxide, silicon dioxide, zirconium dioxide, potassium oxide and chromite sand. 7. The process of claim 1 wherein the additive is at least one of a silica, a metal and sodium. 8. The process of claim 7 wherein the at least one of a silica, metal and sodium is sourced from a waste stream. 9. The process of claim 8 wherein the waste stream is one of a contaminated soil, a sludge, a surface water, and a ground water. 10. The process of claim 1 wherein up to about 40% of the additive is a recycled abrasive. 11. The process of claim 1 wherein the blend is melted at a controlled temperature of from about 1500° F. to about 3000° F. for about 4 hours to about 8 hours. 12. The process of claim 1 wherein the melting takes place in a kiln with an atmosphere of about at least 5% excess oxygen. 13. The process of claim 1 wherein the processing comprises quenching the feedstock to create a fractured product prior to grinding the feedstock to produce an abrasive. 14. The process of claim 1 wherein the processing comprises air drying the feedstock in a mold prior to grinding or crushing. 15. The process of claim 1 wherein the feedstock is processed into an aggregate. 16. The process of claim 15 wherein the aggregate is used for one of a rip rap, a road bed, a rail bed, and a ballast. 17. The process of claim 1 wherein the ground or crushed feedstock is used to produce a product selected from the group consisting of a fracking compound, a proppant, a packing material, a sandpaper product, a grinding wheel, an abrasive, a lubricant, a construction product, an insulation material, a building material, a household good, a filler, a fiber, a bead, a non-woven product, a water jet cutting system, a non-skid surface material, an aggregate and a landscaping material. 18. The process of claim 16 wherein the building material is selected from the group consisting of: a wallboard, roofing material, countertops, and ceramic fixtures. 19. A product produced by the process of claim 1. 20. The product of claim 19 wherein the product is selected from the group consisting of a fracking compound, a proppant, a packing material, a sandpaper product, a grinding wheel, an abrasive, a construction product, an insulation material, a building material, a household good, a filler, a fiber, a bead, a non-woven product, a water jet cutting system, a non-skid surface material, an aggregate and a landscaping material. 21. The product of claim 19 wherein the product is ground into a rounded particle. 22. A process for converting Coal Ash and EAFD into a product comprising: a. preparing a mixture of about 30% by weight of EAFD, the EAFD containing at least iron with about 48% Coal Ash, the Coal Ash containing at least silica and alumina;b. adding about 18% cullet and about 4% titanium dioxide to the mixture to form a blend;c. melting the blend at a temperature from about 2400 degrees Fahrenheit to about 2600 degrees Fahrenheit in a continuous float glass type kiln for about 4 hours to about 8 hours in an oxidizing atmosphere to chemically bind at least one hazardous material contained in the EAFD in a silicate matrix in the feedstock, the feedstock comprising at least one spinel or metasilicate; andd. processing the feedstock by grinding or crushing.
