It is said that life originated from the sea.
Life forms that have continuously evolved and developed over a period of more than three billion years always contain minerals of the same quality as those found in seawater. This means that minerals have been inherited as essential for life forms. Minerals in seawater originate from rocks.
There are many different types of rocks. The Earth's surface layer is divided into the upper crust, lower crust, and upper mantle according to geophysical concepts, and minerals are extracted from representative rocks to determine the properties of their solutions, yielding surprising results as shown in the table below.

Thus, the properties of the solution vary greatly depending on the type of rock. The reason for this is that it reflects the differences in the minerals that make up the rock.
We research and develop mineral solutions with various properties by changing the types of rocks (mineral types) and combinations of rocks, changing the acids and alkalis in the solvent, and changing the reaction conditions.
