Colliery (bismuth)
A mine in the uranium mining of SAG Wismut was called a mine in which ores were crushed, radiologically sampled, sorted and packed ready for delivery. The general mining colliery term , the clear in the uranium mining of bismuth different. Those mines were, in the broadest sense, processing plants for the extraction (mining) objects. In addition, the SAG Wismut operated real processing objects. Like all bismuth plants, the mines were numbered.
Technological background
In the Ore Mountains and Vogtland Gangerz deposits , uranium ores were extracted separately and sorted out on site. So-called step ores and commodity ores (raw ore chunks with a very high or high pitchblend content) came to the property's own mines and were crushed, sampled and sent directly to the USSR . No further (chemical) processing took place. The cross in the recovery of the gangue resulting in degrading the material was as Fabrikerz referred to and next to raw ores of other (non-Gangerz-) deposits fed to the actual processing objects and after the treatment process as Yellow Cake delivered in the USSR. When the last sampling mines were shut down at the beginning of the 1980s, their task was partly taken over by the existing radiometric processing factories (RAF) of the individual mines. The latter, however, only provided for planned dilution or enrichment in order to guarantee a constant uranium content in the raw ore in the chemical processing plants (processing objects). In contrast to a mine, the end products of an RAF were always factory ores.
special cases
Colliery 20
The colliery 20, as a subsidiary of colliery 50 in Aue, was only responsible for the dispatch of all ores from all processing plants to the USSR . It was located at the Aue freight yard and should be viewed more as a warehouse and shipping company. From 1980, the processing objects sent their ore directly and colliery 20 became obsolete, since colliery 50 was also closed.
Fire protection mine Reust
The fire protection mine was responsible for the entire mining operation 90 ( Ronneburg ) and had nothing to do with the further processing of ores. She was responsible for silting up endogenously burning mining fields.
