Copper Tailings

Water Reclamation and 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. (The El Paso smelter is on stand-by status). Water is recovered from the tailings in another thickener. The thickened tailings flow by gravity in large pipes to tailings ponds, where the solid material settles out and additional water is recovered and pumped back to the mill.

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 Limestoney solid after cooling and discarded as waste in dump yards. After suitable crushing, this waste can be utilized as filler in asphalt mixes. Copper
