Why must mine tailings be stored and disposed of carefully

The mining tailings are the leftovers of the porces in which some minerals (the part that they do not want to keep) are separatd from a given ore. This leftovers usually contain some chemical compounds that may be dangerous for the enviroment, and other problem is the fact that some of the separated minerals can be also dangerous, for example things like the arsenic or the mercury.

This is why the mine tailings must be stored and disposed carefully

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
