Ore is a deposit in Earth's crust of one or more valuable minerals.The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire., is used as electrical wire.

2021/12/22These materials include lead-based solder used to join copper pipe, brass and chrome plated brass faucets, and in some cases, pipes made of lead that connect houses and buildings to water mains. In 1986, Congress banned the use of lead solder containing greater than 0.2% lead, and restricted the lead content of faucets, pipes and other plumbing materials to 8.0%.

Instead, they exist combined with other elements as compounds called ores. Ores are raw materials for making metals. Minerals are those in which individual crystals are composed of unit cells or basic unit layers of two or more types. Minerals are inorganic catalysts that function as regulators of metabolic activities in the body.

Lead: Lead is a potential impurity in many color cosmetics, including lipstick. Lead is a well-known and proven neurotoxin that has been linked to learning, language and behavioral problems [6] . Because of this, lead has been eliminated from gasoline and paint in the United States, which has resulted in considerably reduced exposures in the past several decades.
