dec 03, 2015 rare ions that do not participate in the crystallization of common rock-forming minerals become concentrated in the melt and in the excluded water. these ions can form the rare minerals that are often found in pegmatites. rare elements concentrated in large crystals make pegmatite a potential source of valuable ore.In fact, the greener we try to be, the more mining it requires. 2017 study from the world bank makes it clear: clean energy requires far more minerals than the fuel sources it would replace. for example, the amount of wind and solar power needed to meet the goals of the paris climate agreement, would double the demand for the metals used in jul 14, 2020 In 2018, china produced 120 000 metric tons of total rare earths while the US produced a mere 000. the mining of rare earth metals occurs mainly in southeastern china, in provinces like jiangxi and fujian. but there is also mining as north as inner mongolia and as west as sichuan. over the last decade and a half, china has also moved to apr 16, 2021 the government declared rare earths as a critical mineral, explicitly giving its support to all mining companies that plan to delve into or advance operations in this space.jun 18, 2021 kvanefjeld, the ambitious mining project that has caused controversy in greenland since it was first proposed in 2007, is also unique in many ways. the site is claimed to be the worlds second-largest deposit of rare-earth oxides and the sixth-largest deposit of uranium.

It is pegmatites come in two flavors simple and complex, or dirty. the complex pegmatites are the source of many rare minerals used both as gemstones, and rare metal ores. pegmatites being relatively small in comparison to other mineral deposits lend themselves to small mining operations.
