Yes, minerals can precipitate when liquids cool or evaporate. Precipitation is the process by which dissolved minerals come out of solution and form solid crystals. This can happen when the temperature of the liquid decreases, causing the solubility of the minerals to decrease, or when the liquid evaporates, causing the concentration of the minerals to increase.

For example, when seawater evaporates, the concentration of salt increases until it reaches the point where it precipitates out of solution, forming salt crystals. Similarly, when magma cools, the solubility of minerals such as quartz and feldspar decreases, causing them to precipitate out of the magma and form crystals.

The temperature and concentration at which minerals precipitate can vary depending on the specific mineral and the composition of the liquid. Some minerals, such as halite (NaCl), are relatively soluble and will precipitate at relatively low temperatures and concentrations, while others, such as quartz (SiO2), are less soluble and will only precipitate at high temperatures and concentrations.

The precipitation of minerals can be an important process in the formation of rocks and minerals. For example, the precipitation of calcite (CaCO3) from seawater can lead to the formation of limestone, while the precipitation of quartz and feldspar from magma can lead to the formation of granite.
