Identifying Metal & Mineral Samples

There are two things that usually define if non-ferrous metals are going to produce a metallic signal when a metal detector is used on them – the amount of metal that is there and the physical state that it is found in. a metal detector in a real calibrated test mode can quickly define if an ore sample has a predominance either of metal or of mineral. If the specimen does not contain neither metal or mineral or completely equal amounts of both, the metal detector will not let off any indication.

as soon as the electromagnetic field of a search coil of a metal detector is interfered by a good amount of gold, silver, copper, or any other type of valued non ferrous metals, the metal detector signals a metallic response, that is, as long as the metals are in a conductive condition. Due to the fact that there are some rich ores that are in sulfides, tellurides as well as other compounds that are not conductive, they bring about a metallic response no matter how pure they are or what amount there is. Generally though the free milling ores of non ferrous metals usually produce appropriate responses when the ores are found in enough quantities by the metal detector.
