âOhio never left,â says venture capitalist Mark Kvamme, whose Columbus-based Drive Capital fund raised the second largest inaugural round of venture capital ever in 2013 ($250 million) betting on the Midwestâs frothing start-up ecosystem. âPeople just stopped paying attention.â.
A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure formed by geological processes. A rock is an aggregate of one or more minerals whereas a rock may also include organic remains and mineraloids.or example, limestone is a sedimentary rock composed almost entirely of the mineral calcite. Other rocks contain many minerals, and the specific minerals in a rock can vary widely. Some minerals, like quartz, mica or feldspar are common, while others have been found in only one or two locations worldwide.
Minerals are pure inorganic elements (containing atoms of the same element), meaning they are much simpler in chemical form than vitamins. All vitamins are essential or required by our bodies, whereas only some minerals are essential nutrients.
