Chemical sedimentary rocks form by precipitation of minerals from water. Precipitation is when dissolved materials come out of water. For example: Take a glass of water and pour some salt (halite) into it. The salt will dissolve into the water.
metamorphic
They are classified as clastic or non-clastic. Clastic sedimentary rocks are formed from rock particles of various sizes. Non-clastic rocks are formed from precipitation of minerals out of solution or by the lithification of organic matter.
Halite and Gypsum, they are called Evaporites and are both rocks and minerals
A rock's mineral composition is a determining factor in rock identification.

Precipitation
Chemical sedimentary rocks are formed by the precipitation of minerals from water.
Chemical sedimentary rocks are formed from the precipitation from, or evaporation of, water that is saturated with dissolved minerals. In addition, most clastic sedimentary rocks are also formed from the cementing together of sediment particles by the precipitation of minerals from water.

A rock is an agglomeration of different minerals. Minerals are classified into categories based on their chemistry: oxides, sulphides, silicates, carbonates etc. Rocks are classified primarily by the process that formed them: igneous, sedimentary, or metamorphic.

All rocks are composed of combinations of minerals by definition. Sedimentary rocks can be composed of many different minerals and therefore cannot be classified as a specific mineral. Rocks are the source of most minerals for human use, but they must be separated from the other minerals in the rock.
Organic sedimentary rocks are formed from the remains of plant and animal life. Chemical sedimentary rocks are formed from the precipitation of minerals in a solution.

The expulsion of fluids which occupy the pore spaces in sediments gives way to the precipitation of solid minerals which bind the sedimentary particles together into rock.
