Natural Resources of Azerbaijan composed of pyrite and chalcopyrite. Copper-porphyry formations’ ores consist of molybdenum and small amount of noble metals. There are many copper-porphyry formation’s ore in this region except Garadagh and Xarxar deposits (Gedebey ore region). There are copper-porphyte in the Mehmana ore-bearing region (Demirli and Xançincay). Copper-porphyry ore-bearing in the Nakhchivan Autonomous Republic, is mainly located on the Mehri-Ordubad granitoid batholite's exo and endocontact zones (Diakhchay, Goygol, Goydagh etc.). In addition, Halhal copper-pyrite, Goygol, Agridağ copper, Nashirvaz, Kilit-Katam copper-cobalt, Nergirvaz copper-polymetallic are known in this region. Molybdenum field are found in Dalidagh (Teymuruchandagh, Baghırsag, etc.) and Ordubad ore regions (Paraghachay Diachchay).
Ore condition with "u", "v" not zero divisors. In this case, Ore's theorem guarantees the existence of an over-ring called the (right or left) classical ring of quotients. Commutative domains are automatically Ore domains, since for nonzero "a" and "b", "ab" is nonzero in . Right Noetherian domains, such as right principal ideal domains, are also known to be right Ore domains. Even more generally, Alfred Goldie proved that a domain "R" is right Ore if and only if "R" has finite uniform dimension. It is also true that right Bézout domains are right Ore. A subdomain of a division ring which
