The main part of metal detectors is the control box, shaft, and search coil. Control box which has speaker, batteries, and microprocessor coordinates all activities. To protect the food source many companies use metal detectors to check for metal contaminates in the food, and some drug companies use the metal detectors to check for the same thing in drugs.

Besides metal detection, a walk-through metal detector includes and interface for an operator and a control unit plus environmental tolerance, electro magnetic compatibility, and the assurance of quality control. The control box is the brain of a metal detector. The magnetized metallic objects under the ground send a signal to the control box. Metal detectors that are used in mining need to be compact because of the space restrictions so the control unit and the search coil are integrated into a single unit.

This disk comes off the shaft at an angle, which allows it to be held parallel to the ground. Hand held detectors come in various types, professional, commercial, all-purpose, gold metal, beach and metal that is a relic. Many people use metal detectors to comb the beach for treasures, people are looking for coins, or any other type of metals that might produce a wealth of income. If you are walking along a beach you might come across many people with their instruments looking for these treasures. Since 911 security has gotten tougher and many airports and schools have turned to metal detectors, as well and government buildings, hand held metal detectors are often an important part of security procedures.

A great method of locating and preventing the use of dangerous items such as handguns or knives is the hand held metal detector. They are hand held security metal detectors and walk through metal detectors. Walk over or hand held models of metal detectors are normally used in airports.

Best rated walk through metal detectors have high target selection, low rate of false alarm, consistent detection, and a two way directional system. Cheap metal detectors are available in hand held, waterproof, and walk through models. Walk through metal detectors offer quick and effective processing.

Underwater metal detectors can cost around $400-$600. Underwater metal detectors are widely used to locate metallic objects under water. Underwater construction companies use underwater metal detectors for pipeline or cable locating functions. Some of the underwater metal detectors can adjust the search depth.

Advanced security metal detectors use low radiation x-rays for screening. Many metal detectors have microprocessor technology to check for coarse grained food in cornflakes, popcorn and noodles. Advanced gold detectors can also resist dust and moisture. Some of the advanced gold metal detectors have three modes for speed tracking.

Usually, the price of a metal detector starts from $65. Some sites offer price discounts.

Most sites provide a price list for metal detectors. The price of metal detectors may vary, based on features and functions. If you are just starting out it is a good idea to purchase an inexpensive model before sinking the dollars into the hobby.

The precious metal of gold has fascinated humans for thousands of years. But how do we actually get it out of the ground? Let’s take a look at the most common ways to mine gold.

There are two main gold mining methods, one is called “placer” and the other is “vein” mining. And another type of mining is when gold is collected as a by-product in the mining of other metals.

Placer Mining

Placer mining is practiced when the metal is found in unconsolidated deposits of sand and gravel from which the gold can be easily separated because of its high density. The sand and gravel suspended in moving water. Much heavier metal sinks to bottom and is separated by hand.

The simplest method of placer mining is panning. Here the miner swirls the mixture in a pan rapidly enough to carry the water and most of the gravel and sand over the edge while the gold remains on bottom. This was the classic method used by the Forty-Niners during the California gold rush of 1849 and has been immortalized in story, art, and song.

A more efficient form of placer mining uses a sluice box, a U-shaped trough with a gentle slope and transverse bars firmly attached to the trough bottom.

The bars — extending from side to side — catch the heaviest particles and prevent them from washing down the slope.

Sand and gravel are placed in the high end, the gate to a water supply is opened, and the lighter material is washed through the sluice box and out the lower end. The materials are caught behind the bars and are gleaned to recover gold.

Another variation of placer mining is called hydraulic mining. A very strong stream of water is directed at natural sand and gravel banks washing away the lighter materials. The suspended materials treated as if they were in giant sluice box.

Currently the most important placer technique is dredging. A huge shovel of several cubic meters capacity lifts the unconsolidated sand and gravel from soil and mud and the placer process starts.

Vein Mining

Vein, or lode mining is the most important of gold recovery methods. Each ounce of gold recovered requires the processing of about 100,000 ounces of ore. Much gold is deposited in rock veins and this method accounts for more than half world’s total gold production. Gold in veins may be of microscopic particle size, in nuggets or sheets, or in gold compounds. The ore requires extensive extraction and refining.

One-third of all gold is produced as a by-product of copper, lead, and zinc production. Copper must be electrolytically refined to raise its purity from 99% to the more than 99.99% that is required for many industrial purposes.

In the refining process an anode of impure copper is electrolyzed in a bath in which the cathode is a very thin sheet of highly refined copper. This process

creates anode sludge which contains gold in quantities sufficient to make its recovery profitable. One-third of all gold is obtained from such by-products.

Silver and platinum are also recovered from the copper anode sludge in quantities large enough to more than pay for the total refining process.

Extraction, Refining and Uses of Gold

Ore from the gold mine is first crushed in rod or ball mills. This process reduces the ore to a powdery substance. The gold is then extracted by amalgamation with mercury or by placer procedures. Approx. 70% is recovered at this point.

The remainder is then dissolved in dilute solutions of sodium cyanide or calcium cyanide. The addition of metallic zinc to these solutions causes metallic gold to precipitate. This precipitate is refined by smelting and the purification is completed by electrolysis. The sludge produced in this process will also contain commercial quantities of silver, platinum, osmium, and other rare-earth metals.

Gold is one of the first two or three metals, along with copper and silver that was used by humans in these metals’ elemental states. Because of its poor chemical reactivity it was found uncombined and required no knowledge of refining. Gold was used in decorative arts before 9000 BC. And civilizations prized gold for its beauty.

A principal use of gold today is as a currency reserve. For centuries gold was used directly as currency along with silver. During the 19th century, gold assumed the role as the sole basis of the currencies of most nations. Paper money was directly convertible into gold.

World War I, however, disrupted the “gold-standard” system. The original gold standard was gradually abandoned. The United States stopped minting gold coinage in 1934 and the dollar eventually emerged as the principal unit of international monetary transactions.

Since the 1970s, gold has been bought and sold on the world market, with widely fluctuating prices. Today gold reserves maintain only a very indirect relationship with currency values. However, as gold has declined as a currency reserve, its use in industrial processes has risen. On top of this, its beauty and workability continue to give gold an important role in the world’s jewelry industry.
