aluminum sulfate. Ground limestone, while inexpensive and easily available, has very low solu-bility and therefore must be mixed in a slurry and then sprayed across the water surface. Unfor-tunately, the majority of limestone will sink to the bottom of the pond and be covered by sediment rendering it ineffective for continued clay settling.

Calcium chloride

Calcium chloride is an inorganic compound, a salt with the chemical formula CaCl 2 is a white coloured crystalline solid at room temperature, and it is highly soluble in water. It can be created by neutralising hydrochloric acid with calcium hydroxide.. Calcium chloride is commonly encountered as a hydrated solid with generic formula CaCl 2 (H 2 O) x, where x = 0, 1, 2, 4, and 6.

The flat-lying fossiliferous limestone unit is approximately 30 m thick. Overburden comprises 3–4 m of calcrete, the lower 2 m of which is high in clay, which also infills solution cavities and pipes extending up to 20 m below the surface. The limestone is extracted by ripping and dozing, although some blasting of hard bands is required.

Quantifying the Composition of Limestone

Limestone is composed of the mineral calcite, better known to chemists as calcium carbonate, small amounts of clay, silt, chert (silica, SiO 2), and dolomite (calcium-magnesium carbonate, CaMg[CO 3] 2).2 To be called limestone, the rock has to have a composition of over 50% dolomite and calcite, though the exact percentages vary widely.
