Rare earths are essential constituents of more than 100 mineral species and present in many more through substitution. They have a marked geochemical affinity for calcium, titanium, niobium, zirconium, fluoride, phosphate and carbonate ions. Industrially important minerals, which are utilized at present for rare earths production, are essentially three, namely monazite, bastnasite and xenotime. In modern time techniques for exploration of rare earths and yttrium minerals include geologic identification of environments of deposition and surface as well as airborne reconnaissance with magnetometric and radiometric equipment. There are numerous applications of rare earths such as in glass making industry, cracking catalysts, electronic and optoelectronic devices, medical technology, nuclear technology, agriculture, plastic industry etc. Lot of metals and alloys called rare earth are lying in the earth which required to be processed. Some of the important elements extracted from rare earths are uranium, lithium, beryllium, selenium, platinum metals, tantalum, silicon, molybdenum, manganese, chromium, cadmium, titanium, tungsten, zirconium etc. There are different methods involved in production of metals and non metals from rare earths for example; separation, primary crushing, secondary crushing, wet grinding, dry grinding etc. The rare earths are silver, silverymwhite, or gray metals; they have a high luster, but tarnish readily in air, have high electrical conductivity. The rare earths share many common properties this makes them difficult to separate or even distinguish from each other. There are very small differences in solubility and complex formation between the rare earths. The rare earth metals naturally occur together in minerals. Rare earths are found with non metals, usually in the 3+ oxidation state. At present all the rare earth resources in India are in the form of placer monazite deposits, which also carry other industrially important minerals like ilmenite, rutile, zircon, sillimanite and garnet. Some of the fundamentals of the book are commercially important rare earth minerals, exploration for rare earth resources, rare earth resources of the world, some rare earth minerals and their approximate compositions, rare earths in cracking catalysts, rare earth based phosphors, interdependence of applications and production of rare earths, uranium alloys, conversion of ores to lithium chemicals, characterization and analysis of very pure silicon, derivation of molybdenum metal, electoplating and chromizing, electrolytic production of titanium, heat treatment of titanium alloys, tensile properties of alloys etc. The book covers occurrence of rare earth, resources of the world, production of lithium metals, compounds derived from the metals, chemical properties of beryllium, uses of selenium, derivation of molybdenum metals, ore concentration and treatment and many more. This is a unique book of its kind, which will be a great asset for scientists, researchers, technocrats and entrepreneurs.

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1919 edition. Excerpt: ... chapter vi. the yttrium group of rare earths. The elements scandium, yttrium, europium, terbium, gadolinium, erbium, dysprosium, holmium, thulium, ytterbium, lutecium, and celtium constitute the yttrium group of rare earths. This group is divided into three sub-groups: (i) the terbium group, consisting of europium, terbium, and gadolinium; (ii) the erbium group, consisting of erbium, dysprosium, holmium, and thulium, and (iii) the ytterbium group, consisting of ytterbium, lutecium, and celtium; the elements scandium and yttrium occupying positions by themselves. The elements of this group are all tervalent and give rise to oxides of the general formula Ma03; these oxides are basic and yield salts of the type mx3 which are but slightly hydrolysed in solution. Europium, alone of all the elements of this group, gives rise to bivalent salts, mx2, corresponding with an unknown oxide, Eu0. The elements of this group decrease in basicity in the order, Yt, Eu, Gd, Tb, Dy, Ho, Er, Tu, Yb, Lu, Sc, when the basic character is deduced from the order in which they are precipitated from solution by dilute ammonia, but the order becomes somewhat changed if the basicity is deduced from the heat of dissociation of the anhydrous sulphate. As far as the experimental data go the elements have, from this source, the following decreasing order of basicity: Yt (58 9), Lu (58-5), Yb (58-2), Er (57-6), Gd (569), and Sc (54'5). The bracketed figures indicate the heats of dissociation of the anhydrous sulphates.381 The former method of deducing the order of the basicity indicates that the cerium earths, with the exception of samarium, which comes between gadolinium and terbium, are all stronger bases than the yttrium earths.
