Final answer:
An ore is a mineral-rich rock from which metals can be economically extracted. Examples include iron ore, yielding iron, and galena, yielding lead.
Step-by-step explanation:
An ore is a type of rock that contains sufficient minerals with important elements including metals that can be economically extracted from it. Ores are usually oxides, sulfides, silicates, or native metals, and they must be processed to extract the desired metals.
Two examples of ores and their associated parent elements are:
- Iron ore (hematite, magnetite): The parent element is iron (Fe).
- Lead ore (galena): The parent element is lead (Pb).
These metals are obtained from their ores following various processing methods, depending on the ore type and its location.
