What is calcium carbonate and how can it affect mining

A lot of mining equipment also uses water to keep cool enabling equipment to operate for extended periods of time. In most mining operations, water has to travel long distances from the source into the equipment that needs cooling. If calcium carbonate is present, then the pipes carrying this water can easily become blocked by scale or corroded.

My Honey Calcite Crystal Mining Experience Hibiscus Moon

Jul 13, 2016· How These Crystals Came To Be. After the animal living inside the clam shell (Mercenaria permagna) was long gone, calcite crystals began to crystallize from within.How? Well, in Florida mangroves tend to grow along shorelines. At some point, the calcium in the clam shells leached out due to the acid-rich tannins from those mangroves and the hollow areas within the shells provided the
