тиазолидин-2-тиона повышает извлечение свннца в концентрат на 5% при одновреме ном улучшении качества концентрата л-на 9 Таким образом, основное преимущество насто щего изобретени  состоит в повышении технологических показателей процесса флотации свинцесодержащей сульфидной руды. Формула изобретени  Применение 4-метил-4-этил-5-(2,3-диметил-2 ,Здиоксибутилиден)-тиазолидин-2тиона формулы vn ипц С-С-CH C-CNC н I1 i сн. S МП . х/ в качестве собирател  дл  флотации свинецсодержащих сульфидных руд. Источники информации, прин тые во внимание при экспертизе: 1.Патент США, № 3425550, класс. 209-166, 1966. thiazolidin-2-thion increases extraction of svntsa in concentrate by 5% while simultaneously improving the quality of concentrate l-9. Thus, the main advantage of the present invention is to increase the technological parameters of the flotation process of the lead-containing sulphide ore. Claims of the invention.
