Copper metal is a conductor of electricity and heat tool. A good thermal and electrical conductivity is very high. Electric industry is the largest consumer of this element pure copper has a rather gentle and soft nature. So nice to use as a thermal conductor, a conductor of electricity, building materials, and various metal alloy constituents.
Copper is also used for various purposes household appliances, to the biomedical component. Copper can also be combined with other metals to form alloys such as bronze. Iron alloys using copper as brass and bronze are very important All the coins in the U.S. and metals containing copper weapons.
Copper has widespread uses as agricultural poison and as algisida in water purification. Copper compounds such as Fehling solution is widely used in analytical chemistry tests for sugar. But we must also be careful of the nature of this toxic metal. This can occur when copper accumulate in the body due to the use of copper cookware. Elements Cu excess can damage the liver and cirrhosis spur.

Mining the open pit itself is done with several stages of the process of work which includes:
- The Preparation Stage
- Mining Operations
- Processing and Marketing
- Reclamation
* The Preparation Stage
In the preparatory phase of mining activity performed early in the process of extraction or mining of minerals consists of the preparation phase or pre-mining process, and in this activity include:

Prior to the processing of gold in the economy of scale necessary step preproduction through in-depth study of various aspects. One study that needs to be done is to test the mineral content of rock ore to be processed.
The process of analyzing in detail the content of metallic minerals from rock samples taken from the soil in a land that has been in the survey will be a very important mineral content of the metal held in which the function of the activity analysis is to support the production activities in large-scale gold processing.
One form of assessment activities is the analysis of rock samples to see in detail the content of metals contained in the land which will be held in the processing of economic activity.
Where rock samples can be tested on a laboratory analysis. And today has many methods of analysis used in viewing the content of metallic minerals contained in rocks, but it all depends on the required results in testing, as well as methods of analysis using polarized light techniques and electron microscopy which is the best analysis in identifying minerals with very modern equipment.
This method obtained from an analysis of its structure, texture and Mineralogy in specific minerals from rock samples. To get a detailed analysis of the mineral content of rocks need to use the latest analytical techniques such as Fire Assay, Atomic Absorption Spectrometry (AAS), Induced Coupled Plasma (IC), and mass spectrometry. In addition to modern methods of analysis can also be used a simple method by using a chemical solution to see the presence of metallic mineral deposits of gold from rock samples that were analyzed.
This method is very simple and easy to do and very simple, yet has enough sensitivity to accuracy in view of the metal content of gold in rock samples of minerals.The Fire-Assay analysis is the method of choice for the analysis of precious metals traces in ores. All gold bearing alloys or grains and Sterling Silver alloys are assayed by Fire-Assay techniques

Some of the steps used in the test stages of mineral content of rocks that will be done in a simple way is as follows

Metal detector is very important for use in a process of finding land that have potential metallic mineral content. Because the metal detector will be able to respond to the presence of a metal or any type conductive or magnetic materials in rocks in the soil.
How does this metal detector can work to identify the various metals is by testing the conductivity of the metal. A target signal is eliminated for unwanted metal such as the remains of iron & steel, pull tabs, bottle tabs and others in the same group, while increasing target signals high conductive metal such as gold along with brass and silver.
Metal detector is also very useful in the search for gold ore, so by using our metal detector equipment with easy to find a gold metal content.Various types of metal detectors at this time has been widely developed by various manufacturers and some manufacturers of metal detector maker also has characterized the search uses a mineral or metal targets.A metal detector is not much of a complex devices. It has three basic parts.
The first is a coil that can come in many forms, a power supply and a control box. The work lies largely in the control box because it is a part of that beats when there is metal around and ticking this is what's causing the metal detector to do its job.In the use of a detection of gold, a soil condition is affecting the operation of metal detectors is where the heavy minerals and heavy soil conditions will cause the electromagnetic field and result in shrinking the primary weakness of a signal on the metal at depth. And a soil in wet conditions allow greater penetration of the main magnetic field, providing better signal coverage on the basis of soil depth.

These few simple steps that can be used when we will start using a metal detector:
