Abstract: FIELD: mineral processing.  
     SUBSTANCE: proposed invention relates to the field of mineral processing, in particular to the processing of gold-containing ores, and can be used in the processing of other types of ore and non-metallic raw materials. The method for refining precious metal concentrates consists in the fact that the concentrate containing precious metals is subjected to primary disintegration and sequential classification into fractions 10, 8, 6, 5, 4, 3, 2, 1 and 0.5 mm by medium, fine, superfine and extra fine screen sizing on grids with the appropriate cell size. After medium screening, the concentrate above the grid is subjected to repeated disintegration, washing and fine-tuning, in which the dressing is divided into ethels and precious metal particles, and the concentrate under the grid is transferred to the next stage of classification. In fine, superfine, and particularly fine screening, the superlattice concentrate is crushed, in which the precious metal particles contained in the concentrate are flattened and subjected to repeated screening on the same grid, and the sublattice concentrate and the concentrate formed after crushing are subjected to repeated disintegration, washing, final separation and transferred to the next stage of classification. After crushing from the grid and after finishing, the enlarged particles of the precious metal are extracted. After a particularly fine screening at the last stage of classification, the sublattice concentrate that passed through the grid from the previous stage of classification, and the superlattice concentrate after crushing and re-screening, are subjected to final disintegration, washing and final separation, after which the separated precious metal particles are extracted, and the remaining concentrate is referred to as sludge and disposed of as waste. EFFECT: reduction in the loss of precious metals in the concentrate to 0.2% and an increase of at least 10% in the total yield of precious metal from the ore being processed.

Title: Antrieb zum Transport eines Dias in einem Diaprojektor
IPC: G03B23/04
Filed: 1982-06-07
Granted: 1985-02-14
Abstract: Die Erfindung betrifft einen Diaprojektor mit einem Magazin zur Aufnahme der Dias und mit einem auf eine Welle auf gesetzten, durch einen Motor antreibbaren Antriebsarm, der an einem verschiebbaren Rahmen angreift und während einer 360 °-Drehung ein in dem Rahmen gehaltenes Dia vom Strahlengang in das Magazin und ein nächstes Dia vom Magazin in den Strahlengang transportiert. Um ein zuverlässiges und sofortiges Unterbrechen dieser Transportbewegung jeweils nach Beendigung einer 360 °-Drehung des Antriebs arms zu gewährleisten, mußte bisher eine verhältnismäßig starke Feder verwendet werden. Diese wurde durch einen das Einkuppeln bewirkender Stellantrieb gespannt, so daß dieser eine entsprechend große Leistung haben mußte. Demgegenüber kann dieser Stellantrieb erfindungsgemäß für eine geringere Leistung ausgelegt sein, wenn die Feder durch die Drehbewegung des Antriebsarms oder eines mit diesem um laufenden Teiles trennbar ist. Hierzu kann beispielsweise eine am Antriebsarm befestigte Blattfeder dienen, die erst gegen Ende der 360 °-Drehung gespannt zu werden braucht.
