Detailed introduction

Chapter 82

The ore concentrates, which contain copper sulphide and iron sulphide minerals, are treated by pyrometallurgical processes to yield high purity copper products. Oxide ores, which contain copper oxide minerals that may occur in other parts of the mine, together with other oxidized waste materials, are treated by hydrometallurgical processes to yield high purity copper products.

Deep

Oceans have fascinated humans throughout history and the notion of deep-ocean mining goes back to at least 1870 when, in Jules Verne's classic book 20,000 Leagues under the Sea, Captain Nemo announced that, "In the depths of the ocean, there are mines of zinc, iron, silver and gold that would be quite easy to exploit."

Rcovery of gold in pyritic ores

Geologists and mineralogists have many theories why and how the gold occurs with the pyrite, and I will not enter into any of these areas, since I am concerned with liberating the gold from the ores. I will say that from my understanding, many seem to agree that in sulfide gold ores, the occurrence of gold appears to occur as a replacement of other minerals, possibly iron. Get price

7 Effects of Mining and Processing of Mineral Resources

ADVERTISEMENTS: Some of the major environmental effects of mining and processing of mineral resources are as follows: 1. Pollution 2. Destruction of Land 3. Subsidence 4. Noise 5. Energy 6. Impact on the Biological Environment 7. Long-term Supplies of Mineral Resources. Mining and processing of mineral resources normally have a considerable impact on land, water, [] Get price

Iron Ore Smelting Process

The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being Get price

Iron Pyrite or Fools Gold Meaning Uses: Enhances

How does Gold Naturally Form on Earth's Crust

Although gold can potentially be found anywhere on earth, the truth is that most gold is found in the more active parts of our planet, geologically speaking. Most of the original discoveries of gold were made by accident around stream beds where gold particles and nuggets were found washed down from the hills and mountains where most of the gold veins are located.

Heavy Metal Mining Using Microbes

The use of acidiphilic, chemolithotrophic iron- and sulfur-oxidizing microbes in processes to recover metals from certain types of copper, uranium, and gold-bearing minerals or mineral concentrates is now well established. During these processes insoluble metal sulfides are oxidized to soluble metal sulfates. Mineral decomposition is believed to be mostly due to chemical attack by ferric iron Get price

Gold extraction

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.
