Mining and Mineral Use Earth Science

Finding and Mining Minerals. Geologic processes create and concentrate minerals that are valuable natural resources. Geologists study geological formations and then test the physical and chemical properties of soil and rocks to locate possible ores and determine their size and concentration. A mineral deposit will only be mined if it is profitable.

Deep sea mining Wikipedia

Deep sea mining is a mineral retrieval process that takes place on the ocean floor.Ocean mining sites are usually around large areas of polymetallic nodules or active and extinct hydrothermal vents at 1,400 to 3,700 metres (4,600 to 12,100 ft) below the ocean’s surface. The vents create globular or massive sulfide deposits, which contain valuable metals such as silver, gold, copper

Unit 1 Reading: What are Mineral Resources and What Makes

Sometimes actual minerals and rocks are used in products, or to make things. The rock granite is mined to make countertops, and the mineral halite is mined, crushed, and sold as table salt. Other times, minerals and brines are processed to extract one specific element, and these individual elements are also often called commodities. For example
