Host mineral
WebOf the approximately 160 minerals that are known to contain rare earths, only four are currently mined for their rare earths: bastnasite, laterite clays, monazite, and loparite. With the exception of laterite clays, these minerals are good sources of light lanthanides and lanthanum and account for about 95 percent of the rare earths in use. WebThe most common gangue minerals containing gold are: quartz, carbonates, chlorite, graphite (including other carbonaceous material), and tourmaline. Many other minerals are occasional hosts for gold.
