ABSTRACT:
An in situ method of mixing a first material with a second material involves disposing the second material over a layer of the first material, disposing a mixing apparatus through the first and second layers of material, and mixing the first and second materials with the mixing apparatus. The mixing apparatus includes an endless cutting assembly which is movable along a loop path. The cutting assembly includes a plurality of teeth which convey the second material downwardly and mix the second material with the underlying layer of the first material. The method has particular application in converting mineral waste materials such as phosphogypsum into useful mixtures which can be used as construction fill.
