Conductive Minerals and Your Metal Detector August 2014 (Vol. 83

This is why some minerals like galena, an important ore of lead, may set off your detector at one mine, but galena from another mine may not set off your detector at all. . Some detectors have special ground balance settings for salty ground to resist these conditions, and these settings are needed for working on beaches.

mineral? • Ask them to examine a mineral which is an ore of a metal (e.g. galena – lead ore: haematite – iron ore). Ask them to compare the properties of the ore with a sample of the metal derived from it, also provided in their boxes. How might they extract the metal from the ore and what other element might the ore contain?

Extracting Lead Materials from Ore Nuclead

Lead is extracted from ores dug from underground mines. Of the more than 60 minerals that contain lead, only 3 galena, cerussite and anglesite are commercially viable. Usually, lead is found in conjuction with other metals such as silver and zinc. Lead materials are mined as a by product of these other more valuable

Milling and flotation processes remove the zinc and lead minerals from the rock and then concentrates them. First, the rock is ground to a fine powder (almost the consistency of talcum powder) to separate the sphalerite and galena from other minerals that comprise the rock. Flotation is then used to separate and concentrate
