Natural Gypsum is Calcium Sulphate Dihydrate (CaSO4.2H2O) deposited in sedimentary layers on the sea bed. Under high pressure and temperature, Gypsum turns into Anhydrite (CaSO4). Natural Gypsum/Anhydrite is produced from open-cast mines or underground mines. Natural Gypsum is normally only screened to remove 'fines' (mainly mudstones), then crushed and finely ground for …

Rainbow Rare Earths' latest inferred mineral resource for the project was 38.3 million metric tons, larger than the original 35Mt expected from the gypsum stacks. Neodymium and Praseodymium oxide represent 29.1% of the total contained rare earth oxides, with an in-situ value of US$95/t gypsum, said the company.
Rainbow Rare Earths. Rainbow Rare Earths is a mining company with two major opportunities in Africa: the Phalaborwa Project in South Africa and the high-grade Gakara Project in Burundi, East Africa. Rainbow signed a co-development agreement (with the Company holding 70%) in 2020 to recover rare earth elements from two gypsum stacks of circa 35 ...
This entry lists a country's mineral, petroleum, hydropower, and other resources of commercial importance, such as rare earth elements (REEs). In general, products appear only if they make a significant contribution to the economy, or are likely to do so in the future.
Due to the efficiency of the CMP process, it can be used to clean the waste to produce highly saleable high purity gypsum. As an extra benefit, if mineral-rich phosphogypsum is processed using the CMP process, the residual waste provides a concentrated source of rare earth elements which can be sold to specialist refiners.
Rare earths are chemical elements found in the earth's crust that are vital to modern technology. There are 17 elements that are considered rare earth elements. Although they aren't particularly rare, they are difficult to mine, because they do not generally accumulate into rich ores.
The Project comprises approximately 35 million tonnes of gypsum resulting from historic phosphate hard rock mining, containing rare earth elements ("REE") with an estimated average in situ grade of 0.6% Total Rare Earth Oxides ("TREO"), based on previous sampling campaigns.

Rare Earth Metals - This is a group of elements consisting of scandium, yttrium, and the lanthanum group elements. They are known to occur in three areas of the state and two different rocks types. ... Strontium could be a by-product of the gypsum mining as it is found in overburden above the gypsum ore beds. Refs: Hanson, W.D., and McElwaine ...
The Rare Earth ores at Mt Weld contain very low levels of thorium (Th) and uranium (U) and therefore, there are very low levels of naturally occurring radiation present in the tailings. The tailings solids contain approximately 500 ppm ThO 2 and 30 ppm U 3 O 8, which is equivalent to …

Rainbow Rare Earths is also planning to produce rare earths from gypsum stacks generated by hard-rock phosphate mining near Phalaborwa in northeast South Africa. The fact that the stacks are on the surface reduces the cost as only chemical processing, not mining, is needed. Bennett expects "very positive" scoping study results in October.
The gypsum stacks have been built up from some 50 years of hard rock phosphate mining near Phalaborwa. Bennett added the maiden estimate showed that high value Neodymium (Nd) and Praseodymium (Pr) oxide represented 29.1% of the total contained rare earth oxides with an in-situ value of $95/t of gypsum.

Wyoming Gypsum. Gypsum is mined at three locations in Wyoming. Mountain Cement mines small amounts of gypsum near Laramie for use as a retardant in cement. Two plants in the Bighorn Basin of northwest Wyoming mine gypsum and process it into wallboard at nearby plants.
The light rare earth ions have radii similar to that of divalent calcium, and such similarities favour the incorporation of the light rare earths in gypsum. However, the rare earth ions are trivalent, and the charge differences greatly limit the extent of solid state substitution in gypsum, even where the ionic radii are very similar to that of ...
