Basic Mining Definitions n Mine : An excavation in the earth to extract minerals. n Mining : The activity, occupation and industry concerned with the extraction of minerals. n Mineral : Is a naturally occurring inorganic element or compound having an orderly internal structure and a characteristic chemical composition, crystal form and physical properties. n Rock : Any naturally formed aggregate of one or more types of mineral particles.

Basic Resource Economics Definitions n Resources : A concentration of naturally occurring solid, liquid or gaseous material in such a form and quantity that it has the potential for eventual economic extraction. n Reserves : Is the portion of the mineral resource that can be economically mined at a given moment in time. n Ore : A mineral deposit that has sufficient utility and value to be mined at a profit. n Gangue : The valueless mineral particles within an ore deposit that must be discarded (is a particular waste). n Waste : The material associated with the ore deposited that must be mined to get the ore and must then discarded.

Types of Mineral Resources -Metallic n Metallic Ores: Those from which specific metallic elements are extracted. Often, several metals occur in the same deposit. u Ferrous : Contain iron and other elements that are used in the manufacture of steel alloys, e.g., iron, manganese, nickel, molybdenum, tungsten, cobalt, chromium u Nonferrous Metals : Are not closely associated with steel making. t Light Metals – Have lower density than most metals, e.g., aluminum, magnesium, titanium t Base Metals – Named by medieval alchemists who could not convert them to precious metals, e.g., copper, lead, zinc, tin t Precious Metals – Most valued mineral resources, e.g., gold, silver, platinum group, gems t Radioactive Minerals – Exhibit radioactive properties, e.g., uranium, thorium, radium

Types of Mineral Resources – Nonmetallic/Industrial n Nonmetallic Ores: Are used to recover and manufacture numerous distinctive commodities. Usually are composed of abundant minerals and have a relatively low per-ton value. n
