The minerals on Federal lands are divided into three categories, each subject to different laws and regulations. Locatable, which are subject to the Mining Law of 1872, as amended, include gold, silver, copper and other hard rock minerals. Leasable minerals, such as coal and a host of other commodities, are subject to various Mineral Leasing Acts.
Mining in Nigeria is the process by which solid minerals and other useful substances are extracted from the earth. The geological survey of Nigeria has indicated the presence of over 34 minerals that are currently being mined in more than 450 locations spread all over the country.
Biomining is mineral processing with microbes. Biomining is the process of using microorganisms microbes to extract metals of economic interest from rock ores or mine waste. Biomining techniques may also be used to clean up sites that have been polluted with metals. Valuable metals are commonly bound up in solid minerals. Some microbes can oxidize those metals, allowing them
