Quin tipus i subtipus de roca i\/o mineral \u00e9s?<\/strong><\/p>\n

\u00c9s un mineral Molt com\u00fa a els filons de sulfurs disseminats per els roques \u00edgnies .La Galena \u00e9s un mineral natural de l\u2019sulfur de plom.L a calcopirita \u00e9s el mineral de coure m\u00e9s ampliament distribu\u00eft i una de les Principals fonts de este. Pertany a la classe dels sulfurs.
\nComposici\u00f3 qu\u00edmica<\/strong>
\nsoluble en HCl calent amb la producci\u00f3 d \u2018\u00c0cid sulfh\u00eddric (H2S) que \u00e9s reconeix per la su pudor caracter\u00edstica d\u2019ous podrits.<\/p>\n

Breu descripci\u00f3 (color, textura…)<\/strong>
\n\u00c9s tova, densa, fr\u00e0gil, exfoliaci\u00f3 perfecta, opaca, amb llu\u00efssor Met\u00e0l\u00b7lica Molt intensa, pols de color gris fosc.
\nUsos i\/o aplicacions<\/strong>
\nLa calcopirita \u00e9s el principal mineral del coure. Gaireb\u00e9 dos ter\u00e7os del seu pes s\u00f3n el ferro i el coure, tots dos metalls s\u00f3n de gran aplicaci\u00f3 industrial; La galena \u00e9s un dels principals components del plom. A l \u2018Antic Egipte s\u2019utilitzava com a for\u00e7a per a l\u2019kohl, un cosm\u00e8tic emprat per a protegir els ulls. Tamb\u00e9 es va fer servir a l\u2019elaboraci\u00f3 d\u2018esmalts per atuells cer\u00e0mics. Els cristalls de galena van tenir gran utilitat per a les r\u00e0dios primitives com a element Rectific ador dels senyals captades per l\u2019antena, que posteriorment va ser reempla\u00e7at per paper diode.<\/p>\n

Lloc d’origen (Jaciments m\u00e9s importants)<\/strong>
\nLa Galena \u00c9s Pot trobar, per Exemple, a Joplin, Missouri, EUA. A Catalunya n\u2019hi ha nombrosos Jaciments, a els m\u00e9s coneguts dels quals s\u00f3n a la zona de les mines de Bellmunt del Priorat, tancades per a l\u2019Explotaci\u00f3 des de l\u2019any 1972. Tamb\u00e9 n\u2019havia sortit en quantitats variables a la mina Berta (Terme municipal de, Vall\u00e8s Occidental) i a les Mines d\u2019Osor, la Selva. Sant Cugat del Vall\u00e8s.<\/p>\n
