Hi, anybody can help me so I can demonstrate of how to extract copper ore. As the Lab result, the ore has copper, gold and silver content. Request a quote. Innovations: Introduction to Copper: Mining & Extraction. ... To understand the basic principles of copper extraction ... UK pound coins and the gold-colored bits of euro coins are copper ...

If the gold ore is still difficult to be successfully leached after being finely ground, the gold ore is called refractory gold. Generally, the grade of Au in the tailings is greater than 0.5g/t. The gold in this type of ore, either physically wrapped or chemically combined, cannot be in contact with the cyanide solution, so it is difficult to be leached.

26-07-2020· An ore is a rock that contains enough of a metal or a metal compound to make extracting the metal worthwhile. Extraction methods. ... Copper is an example of this.

GOLD EXTRACTION FROM A COPPER BEARING ORE BY THIOSULPHATE LEACHING W. T. Yen, K. Stogran and T. Fujita Gold extraction by cyanidation is reduced to less than 30% as the copper content in the ore is higher than 0 .3% Cu. Thiosulphate leaching process could overcome this problem.

A process for the extraction of copper from a copper ore or concentrate comprises first subjecting the ore or concentrate to agitation leaching at an elevated temperature and pressure in the presence of oxygen and water to obtain a resulting acidic leach liquor which contains dissolved copper. The acidity of the resulting acidic leach liquor is then reduced by affecting percolation leaching of ...
