Calcite / Crushed Marble

Calcite is the most common form of calcium carbonate (CaCO₃). It is a common mineral and a major constituent of limestone and marble. Calcite is an inexpensive crushed and screened white marble media that can be used to neutralize acidic or low pH waters to a neutral, less corrosive effluent. Highly variable in form and color, calcite is best recognized by its relatively low hardness (H = 3) and its high reactivity with even weak acids, such as vinegar. When acidic water reaches neutral pH, no more calcite is dissolved.
Typical Applications

Calcite has more uses than almost any other mineral.
It is used as a filtration media to correct pH to a non-corrosive equilibrium. It is also used in construction materials, abrasives, agricultural soil treatment, construction aggregate, pigment, pharmaceuticals, and more.

Packaging Options

50 lb. bags, poly-lined fiber drums, bulk bags & loose bulk
