That is, the more involved in lead-zinc mining the villagers were, the less they were concerned about the pollution risk from lead-zinc mining. This finding extends our understanding of the psychological typhoon eye effect.Lead processing | Britannica,23-04-2021· Of the more than 60 known lead-containing minerals, by far the most important primary ore of the metal is the lead sulfide galena (PbS). Galena often contains silver, zinc, copper, cadmium, bismuth, arsenic, and antimony; in fact, the value of theLead and Zinc - Energy,and gold. The most common lead-ore mineral is galena, or lead sulfide (PbS). Another ore mineral in which lead is found combined with sulfur is anglesite or lead sulfate (PbSO4). Cerussite (PbCO3) is a mineral that is a carbonate of lead. All three of these ores are found in the United States, which is one of the chief lead-mining countries.WHO | Nigeria: mass lead poisoning from mining activities,,11-11-2011· The response to the mass lead poisoning in Zamfara State has involved multiple agencies, including WHO, United Nations Children's Fund (UNICEF), United Nations Development Programme (UNDP), United Nations Environment Programme (UNEP) - Office for the Coordination of Humanitarian Affairs (OCHA) Joint Environment Unit, Médecins Sans Frontières (MSF), the US CDC, the
