A method of recovering a mineral product from carpet by preparing a feed of carpet pieces; thermally separating organic components from mineral components in the carpet by heating the carpet pieces to a particle bed temperature in the range of 600� C. to 1000� C., wherein the mineral component is oxidized to form a mineral oxide; slurrying the mineral oxide with water to produce 15 to 35% solids slurry within a period of approximately 30 minutes to 24 hours, whereby the mineral oxide forms a mineral hydroxide; stabilizing the pH of the slurry in the range between 6 and 10 by carbonation, resulting in a slurry containing mineral carbonates. |
