Naldrettite is a rare palladium-antimony mineral with the chemical formula Pd\u2082Sb. It is classified as a palladium mineral, an antimonide mineral, and a platinum-group mineral. Naldrettite commonly occurs as microscopic grains in sulfide-rich ore deposits, mafic and ultramafic igneous rocks, hydrothermal systems, and other geological environments containing palladium and antimony. The mineral is generally found as an accessory phase rather than as a major rock-forming mineral. Individual grains are usually very small, commonly less than a few hundred micrometres across, and are commonly attached to or enclosed by sulfide minerals. Because of its small grain size and close association with other platinum-group minerals, naldrettite is normally identified through reflected-light microscopy, […]<\/p>\n","protected":false},"author":1,"featured_media":5086,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_seopress_titles_title":"Naldrettite Mineral: Formula, Properties & Occurrence","_seopress_titles_desc":"Naldrettite is a rare palladium-antimony mineral with the formula Pd\u2082Sb.
