The density of mercury is 13.59 grams per cubic centimeter at room temperature. Mercury is scientifically known as mercury, and its chemical element symbol is Hg. It is the only metal that exists in liquid form at room temperature and pressure. Mercury is a silvery-white, shiny, heavy liquid with stable chemical properties. It is insoluble in acid or alkali. The most common application of mercury is to make industrial chemicals and to be used in electronic or electrical products.
In nature, mercury mostly exists in the form of compounds. Mercury is fond of copper and sulfur, so most of the mercury is distributed in the form of mercuric sulfide. In ancient times, people had already mastered the method of extracting mercury from cinnabar, that is, calcining in the air, collecting the evaporated mercury vapor and condensing the obtained metallic mercury.
Mercury is distributed in very small amounts in nature and is considered a rare metal, but people discovered mercury very early. Natural mercuric sulfide is also called cinnabar. Because of its bright red color, it has been used as a red pigment for a long time.
Mercury is a highly toxic non-essential element that is widely present in various environmental media and food chains, and its traces are found in every corner of the world. Mercury ore is produced in the Lower Cambrian strata, and its output and enrichment are strictly controlled by the structure, rock combination and surrounding rock alteration.
