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.Copper is also used in construction.

Secondary enrichment can affect most classes of ore deposit, but it is notably important in three circumstances. The first circumstance arises when goldbearing rocks—even rocks containing only traces of gold—are subjected to lateritic weathering. Under such circumstances, the gold can be secondarily enriched into nuggets near the base of the laterite.
