The rule describes the assessment and reporting requirements for issuers whose products contain conflict minerals. These minerals â tin, tantalum, tungsten and gold â are used in a wide range of products across numerous industries.
Finding and exploiting mineral deposits requires the application of the principles of geology that you have learned throughout this course. Some minerals are used as they are found in the ground, i.e. they require no further processing or very little processing. For example-gemstones, sand, gravel, and salt (halite) .Most minerals must be processed before they are used. For example: 1  Iron is the found in abundance in minerals, but the process of extracting iron from different minerals varies in cost depending on the mineral.2  Aluminum is the third most abundant mineral in the Earth's crust. Aluminum is the third most abundant mineral in the Earth's crust. 2  It occurs in the most common minerals of the crust-the feldspars (NaAlSi3O8, KalSi3O8, & CaAl2Si2O8, but the cost of extracting the Aluminum from these minerals is high.
