Can metal detectors detect iron ore, such as gold ore?
There are three main types of metal detectors: electromagnetic induction, X ray inspection, microwave detection. It is an electronic instrument for detecting metals. It can be used in many fields.
Detectable.But pay attention to, for ore, iron ore detection sensitivity is much higher than gold, iron less than 1% can be detected, gold needs at least 5 grams / ton or more before you can detect.
In the military, the metal detector can be used to detect metal mines; in the field of security, can detect carry or hidden weapons and tools; in archaeology, can detect buried metal objects of the tomb, and find the treasures of gold and silver jewelry in the tomb or other metal products; in engineering, can be used to detect metal buried underground for example, pipelines and pipelines; in mineral exploration, and found that the particles can be used to detect natural gold; industry, can be used for online monitoring, such as removing cotton, coal, metal and other debris in food. The metal detector can be used as teenagers to carry out national defense education and science activities is also interesting entertainment appliances, toys, especially in recent years, Europe and the United States have a person of interest will be a large scale metal detector, metal detection activities become part of the evolution of outdoor sports
