Applications of Metal Detectors in the Mining Industry
Overview In the mining industry, due to the nature of the working environment, the probability of tramp metal (unwanted metal pieces) being present among ore rocks is very high. Industrial Metal Detectors, with their capability to detect various metal impurities, not only enhance the quality of the final product but also prevent serious damage to equipment and machinery in downstream processing stages.
Difference Between Mining Metal Detectors and Magnets
Magnets are only capable of attracting magnetic metals. In contrast, an Industrial Metal Detector can detect all types of metals, including:
- Magnetic and Non-magnetic metals
- Stainless Steel
- Brass
- Aluminum
- High Manganese Steel
In the mining industry, the product itself is often metallic (mineral ore). Therefore, a mining metal detector must operate with high sensitivity and discrimination to distinguish “unwanted metal” (tramp metal) from the “desired mineral ore.” The dimensions of detectable metals vary depending on the specifications of the machinery and the detector settings.
Why are Metal Detectors Essential in Mining?
The presence of metal impurities in mineral processing not only damages machinery and equipment—such as Crushers, Mills, and Conveyors—but also causes production stoppages, resulting in heavy financial losses. Installing a metal detector guarantees the protection of all equipment and processes against these hazards.
Common Types of Metal Impurities in Mining
Metal impurities can enter production lines from various sources and cause disruptions:
- Excavator and Loader bucket teeth (broken off during material handling).
- Crusher parts detached due to wear and tear (often made of High Manganese Steel, which is non-magnetic and cannot be detected by industrial magnets).
- Bolts and nuts introduced during material transfer.
