Copper Tailing - an overview ScienceDirect Topics Extraction of copper from its ore in copper industries produces two types of waste named as copper slag and copper tailings. The copper slag is produced during the process of smelting for sulphide ore and collected as the material that floats on the top of the molten copper in a furnace. This material ultimately turned into glassy solid after cooling and discarded as waste in dump yards. After,Copper Tailings,The concentrated ore, now called copper concentrate, is dewatered and dried to about 10% moisture content. It is shipped by truck to the Asarco smelter in Hayden, Arizona.

Tailings 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 water and gravityEconomic Potential for reprocessing Copper Mine Tailings,,MLA, to evaluate differences in the mineralogical composition of the ore minerals. Results and Discussion A total of 81 tailings samples were analyzed using XRF, during the survey sampling. The copper grade of the tailings varied between 0.1 % and 1.7 %.
