China'R' Concepts Ltd is a specialty rare minerals exploration and development company, with focus on Tungsten and Tantalum and Niobium. China'R' Concepts Ltd is managed by a high quality and dedicated team of mining professionals with extensive technical and corporate experience in the minerals sector.
Global demand for specialty and rare metals is rapidly growing. This is due to the ascendant craving consumers have, for items derived from these minerals. Articles such as computers, mobile phones, capacitors, etc. Commercially viable deposits of tantalum, niobium and tungsten are very uncommon. Especially in large quantities and under favorable geographic and political conditions.
Tungsten is a metal with unique properties making it an essential component in many industrial applications. Its main properties are - extremely elevated melting point, tremendous density, one of the hardest elements on earth, thermally and chemically stable, great conductor, and environmentally benign.
China accounts for over 83% of world tungsten production. Chinese internal demand has quickly grown in the last 10 years, and China has shifted from an exporter to a net importer of tungsten. This growth in Chinese demand, added to increased controls by the Chinese Government on their domestic tungsten industry, has been decisive for the rising tungsten price.
Extraction or production of tantalum and niobium raw materials of all kinds is widespread, whether by primary industrial mining or artisanal mining. Brazil is currently the major producer. Significant quantities are also produced in China and Congo.
The extraction and refining of tantalum, including the separation from niobium in these various tantalum-containing mineral concentrates, is generally accomplished by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures.
As the focus of the Volta Grande (Brazil) project moves from exploration and development into construction and production, the company´s output and share value will grow significantly.
