Galena, Kansas – A Lead Mining Maven. Galena, Kansas, 1898. In the rocky hills and gravel-filled valleys of southeast Kansas is the small town of Galena, born of rugged characters when lead was discovered in 1877. Before this time, the land was only sparsely settled by hunters and farmers earning meager livings from the rocky and sterile soil.
Proposed mining projects vary according to the type of metals or materials to be extracted from the earth. The majority of proposed mining projects involve the extraction of ore deposits such as copper, nickel, cobalt, gold, silver, lead, zinc, molybdenum, and platinum.

Relation to Mining. The U.S. is the world's largest producer and consumer of refined lead metal. Major mine producers other than the U.S. include Australia, Canada, China, Peru, and Kazakhstan. In the U.S., six lead mines in Missouri, plus lead-producing mines in Alaska and Idaho, accounted for all domestic mine production.
Mercury tailings then become a major source of concern, and improper disposal can lead to contamination of the atmosphere and neighboring bodies of water. Most underground mining operations increase sedimentation in nearby rivers through their use of hydraulic pumps and suction dredges; blasting with hydraulic pumps removes ecologically ...
water pipes and solder. Other sources of lead in the environment include natural activities, such as volcanic activity, geochemical weathering and sea spray emissions, and remobilization of historic sources, such as lead in soil, sediment and water from mining areas. As lead is an element, once it is released into the environment, it persists. 2
