  • Tailings Wikipedia

    Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an oreTailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed The extraction of minerals from ore can be done two ways: placer mining, which uses waterKeywords: copper slag, copper slag flotation tailings, leaching, sulphuric acid, ferric sulphate, hydrogen peroxide Introduction The pyrometallurgical processing of copper concentrates generates large amounts of coppercontaining slag Management options for this slag include recycling, recovery of metal values, production of value added products and disposal (Gorai and Jana, 2003) HoweverRECOVERY OF COPPER FROM COPPER SLAG AND COPPER SLAGThe five basic types of reagent used in froth flotation recovery include collectors, frothers, depressants, activators and modifiers When designing the processing plant, the types and quantities of reagents used should be considered together with any depressing requirements to lessen environmental impacts in the tailings streams (Ritcey 1989)Tailingsfo What Are Tailings?
