The Brazilian newspaper reports that h e has just returned from a round of project presentation in the United States and Canada, where he met with investors interested in three major ore projects: bauxite, iron and rare earths. Bahia is well-acquainted with the mining industry. Brazil's third largest mineral-producing state, it also produces ...

Brazilian miner Vale has discovered deposits of rare-earth minerals at its giant Salobo copper-mine project, a leading minerals researcher said late last week.

In the present study, soil and rock samples were collected from uranium deposits in the city of Pedra, Pernambuco, Brazil. These samples were analyzed using neutron activation analysis to identify the occurrence of rare-earth elements (REE). The most abundant elements found were Ce, Nd and La, with concentrations 12 times higher than the average in the earth's crust and 4.6 times higher …

Brazilian miner World Mineral Resources (WMR) has found a large reserve of neodymium, one of the 17 rare earth elements, in the western Bahia state, which could bring US$8.4 billion to the country.

For some elements, such as the rare earth elements (REEs), the problem is production. Current mines are not sufficient to meet demand for all the metals, particularly dysprosium and neodymium (Vaccari, 2009) (see REE demand breakdown figure below). For other elements, such as uranium, the rare metals, phosphorus and platinum group elements ...

Canada Rare Earth presently has dealings with a number of properties in Canada and internationally for the purpose of securing long term supply of rare earth concentrate. Our strategy has evolved from an initial focus on rare earth exploration to a focus on developing a vertically integrated supply chain connecting mining operations to rare ...

The rare earths crisis requires more than free markets. A recent opinion piece from the Wall Street Journal's editorial board wrongly argues the rare earth minerals crisis isn't as …

The increase in international prices of rare earths, from this imposition of quotas, has also provoked in Brazil a return to the discussion of mining projects of rare earth minerals paralyzed in the 1990s, from both the federal government and private initiative.

As previously reported, Brazil Minerals has now direct ownership of projects in a triad of strategic minerals – lithium, titanium, and rare earths. Areli Nogueira, Vice President of Exploration at the Company, stated, "Lithium is in high demand worldwide and Brazilian lithium reserves are now recognized as some of the best in yield and ...

RIO DE JANEIRO, BRAZIL - Penco, in the Bíobío region, could be home to one of the world's few rare earth processing plants. Peruvian mining company Hochschild, which controls a deposit of these strategic minerals in the area, announced last week in a prospectus filed with the Toronto Stock Exchange that it is studying this possibility to make the project it developed in Chile even more ...

Bastnäsite deposits in China and the United States constitute the largest percentage of the world's rare-earth economic resources, while monazite deposits in Australia, Brazil, China, India, Malaysia, South Africa, Sri Lanka, Thailand, and the United States constitute the second largest segment.

The U.S., South Africa, Canada, Australia, Brazil, India, Russia, South Africa, Malaysia, and Malawi also have deposits of rare earth metals, and while the U.S. Geological Survey expects that global reserves and as yet undiscovered deposits of rare earth metals will be able to meet future demand, new mines may take up to 10 years to develop ...

URANIUM INVESTIGATIONS IN BRAZIL THE MORRO DO FERRO THORIUM AND RARE-EARTH ORE DEPOSIT, POCOS DE GALDAS DISTRICT, BRAZIL By HELMUTH WEDOW, JR. ABSTRACT Rare-earth elements and thorium are closely associated with a large magnetite stockwork cutting alkalic igneous rocks at Morro do Ferro on the Pogos de Caldas Plateau in southern Brazil.

Rare earths elements (REEs) are a group of 17 chemical elements, including the 15 lanthanides as well as Scandium and Yttrium. They are divided into two groups according to their numbers and atomic masses, namely: Light Rare Earth Elements (LREE) and Heavy Rare Earth Elements (HREE) (Šmuc et al. 2012).Rare earth elements have homogeneous physicochemical …

Global resources of heavy Rare Earth Elements (REE) are dominantly sourced from Chinese regolith-hosted ion-adsorption deposits in which the REE are inferred to be weakly adsorbed onto clay minerals.

The rare-earth elements, also called the rare-earth metals or (in context) rare-earth oxides, or the lanthanides (though yttrium and scandium are usually included as rare-earths) are a set of 17 nearly-indistinguishable lustrous silvery-white soft heavy metals. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and ...

The mineral exploration of rare earth elements (REEs) and their entry into the soil via fertilizers has generated concern about environmental impacts and human health risks. We evaluated 60 samples of limestone, gypsum and phosphate fertilizers marketed in Brazil in order to characterize their conte …

Rare Earth Element Production: This chart shows a history of rare earth element production, in metric tons of rare earth oxide equivalent, between 1950 and 2020. It clearly shows the United States' entry into the market in the mid-1960s when color television exploded demand.

Brazilian rare earth element (REE) deposits are associated with carbonatite–alkaline complexes, granitic intrusions, and marine placers. The Araxá project is an example of an REE deposit associated with alkaline carbonatite rocks; it has an estimated resource higher than 40 million tons (Mt) of 3.0% REE 2 O 3 as a byproduct of niobium tailings and is the most advanced REE project in Brazil.

Rare earths, "vitamins of modern society" Rare earths refer to a set of 17 chemical elements (scandium, yttrium and the fifteen lanthanides). Contrary to what their name seems to indicate, rare earths are no more rare than other more common metals: their concentration in the earth's crust is, for example, higher than that of gold or silver and similar to that of copper or zinc.
