A long-term effective cooperation with suppliers from CIS countries and Eastern Europe allows the Concust GmbH & Co KG to claim that we know and we fulfill all international requirements which are imposed to sending, processing and reception of deliveries. One of the most important directions of our activity is the reception and the following processing of ores and the minerals confollowin tantalum and niobium, and also the purchase of scrap from precious metals. We accept scrap of precious metals in any forms: the chemical equipment, wastage in the form of a crumb and powder, a wastage of a foil, wires and stampings, condensers, crucibles, an electronic equipment, radioelements, a laboratory dishes, slags, ashes, thermoconverters, etc.

Tantalum-niobium ores, ore concentrates and minerals.

The raw materials used for production of niobium and tantalum.

The main minerals containing Ta and Nb are tantalite, columbite, manganotantalit, pyrochlore, loparit, plumbomikrolit, vodginite, microlith, iksiolit. Besides ores of tantalum are known in the rear metal pegmatites of alkaline and granite breeds, in hydrothermal veins, etc. Also tantalum can be received from tin ores, it is a by-producme at production of tin (slags of plants contain from 3 to 15% (Ta, Nb) 2O5). Some tantalum is taken from the wolframs greisen fields. The average maintenance of Ta2O5 in ores — 0,012 - 0,03%. Two minerals — columbite (Fe, Mn) (Nb, Ta) 2O6 and tantalite (Fe, Mn) Ta2O6 are the most preferable to processing. These minerals almost always contain impurity of tungsten, tin, titan and other elements.

Ores and non-ferrous scrap

Our company accepts and processes color scrap. We carry out the chemical and radiation analysis, sorting, weighing, and also precise definition of structure of any alloy. Thus, for example, we buy constantly tungsten ores, a concentrate and dead catalysts (minimum content of W-10 of %), all other types of tungsten wastage and the grinding powders contain W.

Scrap from gold, silver, platinum and platinum metals

Reception and the following subsequent of scrap from precious metals allows to keep natural resorses of the planet, and also to fill their shortage in the industry. At present our company provides the partners practically all range of services in the markets of gold, silver and platinum metals. We realize the collecting, storage and processing of the wastage and scrap, containing precious metals.
