what the ore mine is used for

High School Earth Science/Mining and Using Minerals - Wikibooks .Surface mining is used to obtain mineral ores that are close to Earth's surface. The soil and rocks over the ore are removed by blasting. Typically, the remaining ore is drilled or blasted so that large machines can fill trucks with the broken rocks. The trucks take the rocks to factories where the ore will be separated from the.what the ore mine is used for,Innovations: Introduction to Copper: Mining & ExtractionHowever, successful exploration for new mineral deposits, technological advances in mining and extractive metallurgy (which enable the exploitation of leaner ores, thereby enlarging the pool of known reserves) and copper uses (which permit copper to be used more sparingly where larger quantities were used in the past).

After recovery, the metals may be still further refined (purified) or alloyed with other metals, as in a copper refinery or steel mill. Mining, processing, and refining are thus successive steps in the utilization of an ore deposit to yield a metal. William Andrew Hustrulid.
