About The Mine Steenkampskraal Rare Earths Mine
Steenkampskraal is a highgrade, hardrock, vein monazite deposit with a resource that has recently been expanded by extensive drilling work, as reported in the mines NI 43101 compliant Mineral Resource Estimate. The underground insitu average grade is 14.36%. There are also surface tailings stockpiled as a result of previous mining and processing operations with a grade of about 7% TREO.
Processing of monazite sands Iowa State University
Processing of monazite sands Abstract For the past ten years, much effort has been expended by several research teams to develop an economic process for recovering thorium, rare earths and uranium from monazite sands.
Leaching of rare earths elements (REE) past and present
Monazite can contain up to 70% REE, primarily Ce and La as well as significant amounts of Nd, Pr and Sm. The Th content is also quite high, ranging from 4 to 12% which is a concern in monazite processing.

Locations of Deposits
Thorium is mined in conjunction with uranium, so much that estimates of reserves for these elements are made based off of uranium content. Thorium is typically found in the minerals thorite, thorianite and monazite however monazite is the only mineral from which Thorium is currently mined. These monazite deposits are found in placer deposits.

Bastn228;site
Bastn228;site and the phosphate mineral monazite are the two largest sources of cerium and other rareearth elements. Bastn228;site was first described by the Swedish chemist Wilhelm Hisinger in 1838. It is named for the Bastn228;s mine near Riddarhyttan, V228;stmanland, Sweden.
Monazite
StructureMonazite is a reddishbrown phosphate mineral containing rareearth metals. To be more specific, it represents a group of minerals. The most common species of the group is monazite(Ce), that is, the ceriumdominant member of the group. It occurs usually in small isolated crystals. It has a hardness of 5.0 to 5.5 on the Mohs scale of mineral hardness and is relatively dense, about 4.6 to 5.7 g/cm . There are at least four different quot;kindsquot; (actually separate species) of monazite, depending on relative elemental co

Monazite A rareearth phosphate mineral.
Monazite is produced from heavymineral concentrates and then separated out by specific gravity, magnetic processes, and other processes. Specimens are sandgrain size particles. What is Monazite? Monazite is a rare phosphate mineral with a chemical composition of (Ce,La,Nd,Th)(PO 4,SiO 4).
Thorium processing Britannica
Thorium processing, preparation of the ore for use in various products. Thorium (Th) is a dense (11.7 grams per cubic centimetre) silvery metal that is softer than steel. It has a high melting temperature of approximately 1,750 176;C (3,180 176;F). Below about 1,360 176;C (2,480 176;F), the metal exists in the
SEPARATION AND RADIOLOGICAL IMPACT ASSESSMENT OF
The processing of mineral monazite to produce thorium (Th) and rare earth elements may create a radiological impact if the processing and residue are not properly or safely managed. Malaysian Atomic Energy Licensing Board (AELB) categorized monazite as a radioactive material because the concentration of thorium in the mineral is higher than 1Bq/g.
Mineral processing Concentration Britannica
Mineral processing Mineral processing Concentration Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In largescale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation), magnetic
