Copper Tailing - an overview ScienceDirect Topics

The properties of copper tailings, a fine-grained residue waste produced from beneficiation of copper ore, and their effects on the properties of bituminous mix were studied by Oluwasola et al. (2014, 2015). The copper tailings were used at 20% content as a fine

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. (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 ...

Mine tailings: reprocess, recover recycle – The ...

Say a copper mine produced 1Mt of metal in 1999 at 90% recovery. The remaining 10% of copper, around 111kt, went to tailings. If the average copper price in 1999 was US$1,500/tonne then that 10% represented US$166.5 million of metal.

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 ...

If one cared to look up historic copper production figures and average ore grades, then it would also be possible to estimate the quantity of tailings that reside in legacy facilities. I’ll be honest, I have better things to do with my time. However, we know that copper has been mined commercially for well over 100 years. We can therefore assume that hundreds of billions of tonnes of copper ...

Data Dump: Tailings Dump - The Land Desk

Tailings are the leftovers from mining. After the ore is gouged from the earth, the target metals—which make up a tiny percentage of the ore—are extracted via milling, smelting, cyanide-leaching, or a combination of these methods. Then everything that’s left, which usually consists of a slimy sludge and makes up one of the biggest ...
