What's the process of paper chromatography

In paper chromatography, substances are distributed between a stationary phase and a mobile phase. ... When a colored chemical sample is placed on a filter paper, the colors separate from the sample by placing one end of the paper in a solvent.

i think it is true since you can test the answer and can use observations to complete it.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
