方解石在微酸性条件下表面析出一层CO2薄膜，并在压强降低的过程中成为微泡的晶核而逐渐生长，使气泡优先附着在方解石表面，使方解石获得更好的可浮性。

The calcite surface can dissolve out CO2 film layer in acidic conditions , it can become the crystal nucleus , then grows into microbubble by reducing pressure , these bubbles can be attached to the surface of calcite , makes calcite particles has better flotability .
