Cerussite
The composition of white lead ore is lead carbonate, which is sometimes partially replaced by silver or chromium. It belongs to the carbonate, aragonite group, and orthorhombic crystal system, and reacts with dilute acid to produce carbon dioxide bubbles, containing 77.6% Pb. The crystal is in the form of a plate-like or pseudo hexagonal bipyramidal shape, and it is common to run through twin crystals. Generally, it is a dense block like aggregate, bell like emulsion, or soil like structure. White or light yellow, brown, and other colors. Diamond luster. Hardness of 3-3.5, density of 6.4-6.6. Bubbling when encountering hydrochloric acid. It is a secondary mineral of galena that has been oxidized on the surface. Usually used together with galena to extract lead or prepare various lead compounds
Phosphate chloride lead ore
Phosphorus chloride lead is produced in the oxidation zone of lead deposits and is a product of the interaction between phosphoric acid and lead minerals in surface water. Phosphate chloride lead ore has good ornamental value due to its bright color and dense hexagonal columnar crystals. The quantity of this type of mineral is also small, making it precious.
Galena
Galena is a common mineral that is a sulfide with a metal (lead) to sulfur ratio of 1:1. It is the most important ore for lead and also an important source of silver. Galena is one of the most abundant and widely distributed sulfide minerals. Galena (also known as lead sulfide) is a common mineral and an important ore mineral for extracting lead. It is the most widely distributed lead mineral. Galena is a gray lead sulfide, and China has been extracting lead from galena since before the Shang Dynasty. Galena has a cubic shape, and many of these cubic crystals come together to form granules or blocks.
