Rare metal mill-products
Relevance
Despite the fact that rare metals began to be mastered by the industry relatively recently, they are now widely used by high-tech industries. They are mined either directly from deposits, or from waste during the development of other types of minerals. The raw materials of rare earth elements today are represented by both small mining objects and giant deposits, which make it possible to calculate the production of these metals for several hundred years.
general characteristics
Geologists classify as rare metals about 36 chemical elements from the periodic table, the development of which began actively less than 100 years ago. Many of these elements (rhenium, hafnium, gallium, scandium, germanium) were discovered much earlier, but their properties, unlike noble metals, became known to mankind only in the 20th century. Initially, they were treated as exotic, hence the name «rare metals», which can be called conditional. The name has nothing to do with their physical and chemical characteristics or insufficient prevalence in nature. According to many researchers, this group of metals is united, first of all, by the novelty of practical application. The insufficient content of these elements in the earth’s crust, the difficulty of the technological processes of isolation are relevant only for some of them. It is safe to say that today the concept of «rare metals» does not have a direct semantic meaning, since they are widely used in various industrial areas.
Usage
Most often, rare metals are high-tech materials. For example, lithium made it possible to produce miniature and at the same time capacious batteries that can be recharged. Niobium has become the basis for the production of superconducting materials with a high current density, tantalum is used in the manufacture of capacious miniature capacitors, and hafnium is used in the manufacture of corrosion-resistant heat-resistant alloys. Miniature powerful permanent magnets are made from samarium, and reliable semiconductor devices are made from indium or gallium. Modern night vision devices and high quality fiber optics would not be possible without germanium.
Through research, modern scientists continue to discover new properties of these metals, expanding their practical use. If at the dawn of the development of rare metals they were in demand only by the defense industry, today they are actively used in the manufacture of packaging containers, batteries, tiles, sanitary ware, semiconductors. The production and consumption of rare metals today is progressing at a tremendous pace, overtaking other metals, the demand for them in actively developing areas is increasing annually by 15−25%. As for prices, their range is very large. The cadmium series is close to zinc and lead, while others are close to the platinum group metals (scandium, lutetium).
