Caribbean calcite is a recent discovery in the world of minerals, notable for its unique combination of blue calcite and white and light brown aragonite. This combination creates a stunning visual effect, reminiscent of a serene ocean scene. The blue calcite in Caribbean calcite often has a soft, tranquil hue, much like clear, shallow waters.

What equipment is needed for processing? Calcite crushing process. There are three main technologies in calcite processing: crushing, sand making, and milling, and crushing is the primary stage.
