They revealed a content of 31, 28% copper and 0.59% cobalt respectively for the chalcopyrite and heterogenite samples. A first series of pre-leaching tests of the heterogenite and chalcopyrite were carried out in order to reduce the interference of the different soluble minerals present in the studied samples.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786204921457\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9786204921457","offer_id":40272006905949,"sku":"9786204921457","price":39.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/98a57e2e-24d3-4cf0-9aaf-3fc3a619c086.png?v=1758262276","url":"https:\/\/shop.autorenwelt.de\/products\/galvanic-interaction-between-cobalt3-oxide-and-chalcopyrite-in-the-presence-of-active-carbon-during-leaching-von-clomi-kembia","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
