Twin minerals lead and zinc

The great majority of zinc deposits contain the lead mineral, galena, and both the lead and zinc minerals are mined together. Other metals that are found with zinc are silver and copper. Zinc-Copper ores could be smelted into brass. Zinc also exists as a variety of salts and combines with other elements, such as chlorine, oxygen, and sulphur
