  • Heavy mineral sand Sandatlas

    Heavy mineral sand is a natural mineral concentrate which is often mined commercially. Zircon, gold, ilmenite, rutile, monazite, and cassiterite are some noteworthy heavy minerals that are often extracted from sand. Heavy mineral sand is not rare, but its area of occurrence is usually limited.

    Heavy Mineral Analysis Heavy Minerals Analysis

    Most sands are composed for 99% of light minerals such as quartz (s.g. 2.65) and feldspar (s.g. 2.54 2.76). Therefore, sands are mainly distinguished on the basis of their variable heavy mineral content. Heavy minerals are considered to be those minerals with a specific density greater than 2.8.

    Virginia Geologic Survey Heavy Mineral Sands

    These heavy mineral deposits formed in beach and dune sands about 3 to 4 million years ago during the Pliocene Epoch, when the Atlantic Ocean shoreline was at a higher elevation near the present location of Richmond. Ilmenite, leucoxene, rutile, and zircon make up approximately 80 percent of the heavy mineral concentrates produced by Iluka.

    Heavy Minerals Sandatlas

    Heavy minerals sometimes get naturally concentrated as a heavy mineral sand and there were, of course, no bromoform involved. It was moving water either in a stream or beach that did the job. Sometimes the sand is so concentrated in heavy minerals that it has a real economic value as an ore. Sand collectors also love these black sand deposits.
