The purpose of this investigation was to study the sulfuric acid digestion of raonazite sand, and to prepare a thorium-containing ra^-terial from the resulting solution.
Monazite dominates more than 30 carbonatite-related REE deposits around the world, including currently exploited mineralization at Bayan Obo and Mount Weld. These deposits are widely distributed across all continents, except Uses of Hematite (Pigment) The name hematite is from the Greek word "haimatitis" which means "blood-red." That name stems from the color of hematite when it has been crushed to a fine powder. Primitive people discovered that hematite could be crushed and mixed with a liquid for use as a paint or cosmetic. Bastnaesite, a cerium fluoride carbonate, CeCO3(OH,F), found in contact metamorphic zones and pegmatites; cerium is commonly substituted by light rare earths, lanthanum, yttrium, and thorium. It ranges in colour from wax-yellow to reddish-brown.

Monazite has been identified in Cerium, Lanthanium, Neodymium and Praseodymium rich versions. Cerium dominates in nearly all monazite deposits. It also normally contains some Thorium and Uranium, as well as some silica. Monazite describes a group of several closely related phosphates with a varying range of several rare earth elements. Due to the similarity and indistinguishable visual differences of the members, a distinction between the Monazite types are rarely designated, with specimens simply labelled as Monazite. Monazite is a primary ore of several rare earth metals most notably thorium, cerium and lanthanum. All these metals have various industrial uses and are considered quite valuable.
Notes. Monazite was added in Elite Dangerous: Beyond Chapter Four (3.3).
Monazite is used today as a source of REEs in both China and India, where it is considered an attractive feedstock due to its high REE content (up to 65% REE by weight) and the relatively high
Monazite is an ore of a) Titanium b) Zirconium c) Iron d) Thorium. Solution(By Examveda Team) Monazite is an important ore for thorium, lanthanum, and cerium. La monazite è un minerale fosfatico di colore marrone-rossiccio, contenente metalli delle terre rare.Si presenta di solito in piccoli cristalli isolati.
Monazite occurs as accessory minerals in igneous, metamorphic, and sedimentary rocks. In addition, monazite is found throughout the world in placer deposits, beach sands, and is also a component of the ores of the Bayan Obo deposit (Table 6 and Fig. 20). Monazite is a phosphate mineral containing approximately 70% REE oxides.

It can be used with both Th-rich phases and more U- rich phases, such as zircon or xenotime. Monazite is a reddish-brown phosphate mineral containing thorium and sometimes uranium, making it radioactive. — In-Game Description Monazite is a rare Mineral Commodity that can be mined from Hotspots in metal rich or rocky Planetary Ring Systems. Monazite was added in Elite Dangerous: Beyond Chapter Four (3.3). Solution (By Examveda Team) Monazite is an important ore for thorium, lanthanum, and cerium. It is often found in placer deposits.

It is often found in placer deposits. India, Madagascar, and South Africa have large deposits of monazite sands. The deposits in India are particularly rich in monazite.
