  • What is the difference between Lime and Ground Calcium Carbonate (GCC)

    a. Lime is produced by heating limestone in a kiln to change the mineral into calcium oxide, and calcium carbonate (aka: pulverized limestone or fine grind) is produced by pulverizing high-grade calcium minerals, in Pete Lien & Sons' case limestone, into a ground granular or power sized finished product.

    b. Pete Lien & Sons sells both Lime and Calcium Carbonate, but each product is produced at different locations.

    c. Lime is produced out of our Rapid City Complex, Frannie Complex, and Colorado Hydrate Complex, while Calcium Carbonate is produced out of our Owl Canyon Complex.

  • Does Pete Lien & Sons sell AgLime

    Yes, the name 'AgLime' is a bit deceiving because it is not lime, instead it is agricultural crushed limestone. Pete Lien & Sons sells 'AgLime' out of the Owl Canyon Complex via Ground Calcium Carbonate.

  • What do you mean by ‘Fine Grind’?

    a. Fine Grind is the process of pulverizing limestone

    b. There are many different names for Fine Grind material. They include; pulverized limestone/mineral, ground calcium carbonate (GCC), cal. carb., mineral filler, and AgLime to name a few. To complicate things further, each fine grind manufacturer has a different brand name for pulverized limestone.
