Applied Geochemistry in Mineral Exploration and Mining

THE BASIS OF GEOCHEMISTRY IN DISCOVERING AND EXPLOITING ORE DEPOSITS. A basic tenet in exploration and environmental geochemistry is that elevated concentrations of metals and compounds in ore deposits or from anthropogenic sources will disperse with time and be recorded as aberrations against "normal" background levels.

more economical it is to mine. Thus we define an ore as a body of material from which one or more valuable substances can be extracted economically. An ore deposit will consist of ore minerals, that contain the valuable substance. Gangue minerals are minerals that occur in the deposit but do not contain the valuable substance.
