Copper extraction Wikipedia

For economic and environmental reasons, many of the byproducts of extraction are reclaimed. Sulfur dioxide gas, for example, is captured and turned into sulfuric acid — which can then be used in the extraction process or sold for such purposes as fertiliser manufacture. Oxidised copper ores can be treated by hydrometallurgical extraction.

Gold extraction Wikipedia

Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of

How to Use Bleach on Gold Ore to Remove Gold Sciencing

Pour the acid-and-bleach mixture into the plastic bowl with the ore grains and stir. Allow four hours for the gold to dissolve, stirring every 20 minutes. The chlorine reacts with the gold inside the ore to form gold chloride. Filter the ore and bleach solution to remove all the impurities, such as soil and rock fragments.

Extracting Gold HowStuffWorks

As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon. Filtering the pulp through screens separates the gold-bearing carbon. The carbon moves to a stripping vessel where a hot caustic solution separates the gold from the carbon.

Extract copper and gold from low-grade ores FLSmidth

In copper, the existing ore bodies are becoming lower grades, they are deeper, and they are more complicated to process. The ROL technology makes it possible to recover more copper from low-grade concentrates. Deposits unsuitable for smelting can be developed as they can be suitable for the leaching process, providing renewed business cases for new and remaining deposits.

Eliminating Copper from Gold Ore

When reviewing Methods of Eliminating Copper from Gold Ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidation. Preliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite, azurite and chrysocolla but these acids have but little effect on sulphide copper

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with
