Bacterial Leaching Extracting Gold from it's ore?

Apr 14 2008The higher oxidation state iron is then reactive enough to strip gold away from its ore Gold is oxidized in this process and dissolves into solution where it can be extracted easily Au(3+) -- Au(5+) There are other mechanisms this one being the most widely used Traditional methods used to extract gold from ore (chemical methods) Get price

The Extraction of Copper

Extracting copper from its ores The method used to extract copper from its ores depends on the nature of the ore Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate carbonate or sulfate ores Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper Get price

Image

Gold mining

It is particularly appropriate for low grade gold and silver ore processing (e g less than 5 ppm gold) but its use is not restricted to such ores There are many environmental hazards associated with this extraction method largely due to the high acute toxicity of the cyanide compounds involved Get price

Gold Extraction and Recovery Processes

available for the extraction of gold metal from its ores Amongst these methods cyanidation is the most common method used in the leaching of gold from the ore This process involves the dissolution of gold containing ores in dilute cyanide solution in the presence of lime and oxygen For refractory ores such asGet price

Mining And Mineral Processing

Once a suitably sized deposit of a mineral has been found mining can begin In ancient times mining and mineral processing were very primitive and the main method used to extract ores was digging by hand Mining is largely divided into surface and underground mining Minerals are often found in river beds beach sands and other sandy areas Get price

How Are Metals Extracted From Their Ores?

Quick Answer Metal extraction from ores occurs in many different ways involving physical chemical and electrical means Even ores of the same metal sometimes require different methods of separation depending on the concentration of the metal and its chemical composition within Get price

Image

How gold is made

4 The gold is then separated from the ore using one of several methods Floatation involves the separation of gold from its ore by using certain chemicals and air The finely ground ore is dumped into a solution Floatation cyanidation and the carbon-in-pulp method are 3 processes used to refine gold Get price
