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 extension which means that "δ" is a homomorphism of abelian groups satisfying Then the Ore extension "R"["x";"σ","δ"], also called a skew polynomial ring, is the noncommutative ring obtained by giving the ring of polynomials "R"["x"] a new multiplication, subject to the identity If "δ" = 0 (i.e., is the zero map) then the Ore extension is denoted "R"["x"; "σ"]. If "σ" = 1 (i.e., the identity map) then the Ore extension is denoted "R"["x","δ"] and is called a differential polynomial ring. The Weyl algebras are Ore extensions, with "R" any commutative polynomial ring, "σ" the identity ring endomorphism, and "δ" the
