Quin tipus i subtipus de roca i\/o mineral \u00e9s?<\/strong>
\nEl coure \u00e9s un mineral de la classe dels elements natius, que pertany al grup de minerals del coure.
\nElements natius: els elements natius s\u00f3n aquells elements que es produeixen en la natura en forma no combinada amb una estructura cristal\u00b7lina diferent. La classe dels elements natius inclou els metalls, com el coure, l\u2019or. i entre altres elements espec\u00edfics.<\/p>\n

Formaci\u00f3 de la roca i\/o mineral<\/strong>
\nEls jaciments de coure estan relacionats amb roques ultrab\u00e0siques constitu\u00efdes per minerals rics en ferro i magnesi, encara que tamb\u00e9 s\u2019origina degut a determinats processos qu\u00edmics en jaciments de sulfurs.
\nEs troba en masses ben visibles en cavitats de basalts i conglomerats. A les mines velles de coure
\nabandonades es bastant f\u00e0cil trobar incrustacions de coure a sobre d\u2019objectes de ferro.<\/p>\n

Composici\u00f3 qu\u00edmica<\/strong>
\nCoure (Cu): 100,00%. F\u00f3rmula qu\u00edmica: Cu<\/p>\n

Breu descripci\u00f3 (color, textura.)<\/strong>
\nEl color del coure, com el seu nom indica, \u00e9s el color coure. El seu lustre \u00e9s met\u00e0l\u00b7lic i \u00e9s opac (no transl\u00facid). La ratlla que deixa el coure (per exemple, si ratllem una paret) \u00e9s rosa. \u00c9s un material molt tou (de 2-3 en l\u2019escala de Mhos) i molt mal\u00b7leable, i les seves fractures s\u00f3n estelloses. El coure cristal\u00b7litza en sistema c\u00fabic, per\u00f2 els cristalls (c\u00fabics o octa\u00e8drics) s\u00f3n molt estranys.<\/p>\n

Usos i\/o aplicacions<\/strong>
\nEl coure natiu en estat pur molt estranyament es presenta en quantitats suficients com per a ser explotat industrialment, per aix\u00f2, per als seus diferents usos, el coure s\u2019extreu de diversos materials, com per exemple, la cuprita (\u00f2xid de coure), la calcolita (sulfur de coure) i altres. Actualment, el principal \u00fas del coure t\u00e9 lloc en l\u2019\u00e0mbit de l\u2019electr\u00f2nica. Al ser d\u00factil i conductor de l\u2019electricitat, s\u2019utilitza en l\u2019obtenci\u00f3 de cables i fils de totes les dimensions.<\/p>\n

Lloc d’origen (jaciments m\u00e9s importants)<\/strong>
\nEls jaciments m\u00e9s importants es troben a:
\n\u2022 Arizona
\n\u2022 Nova Jersey
\n\u2022 Estats Units (USA)
\n\u2022 Alemanya
\n\u2022 Finl\u00e0ndia
\n\u2022 Xile
\n\u2022 R\u00fassia
\n\u2022 Z\u00e0mbia
\n\u2022 Espanya: Ast\u00faries, Guip\u00fascoa, Ja\u00e9n, Huelva, Pirineus d\u2019Arag\u00f3<\/p>\n
