Abstract
Изобретение относитс к технологии минеральных солей, в частности к технологии переработки сильвино-карналлитовьпс руд, и обеспечивает переработку таких руд с малым содержанием MgCIj The invention relates to the technology of mineral salts, in particular to the technology of processing sylvino-carnallite ores, and provides processing of such ores with a low content of MgCIj
Description
Изобретение относитс к технологии минеральных солей, в частности к технологии переработки сильвине карналлитовых руд с малым (1 10 мас.%) содержанием MgClj.The invention relates to the technology of mineral salts, in particular to the technology of processing sylvite carnallite ores with a low (1-10 wt.%) MgClj content.
Цель изобретени - обеспечение возможности получени обогащенного карналлита из калийных руд с содержанием 1-10% MgCIj с одновременным получением хлористого кали .The purpose of the invention is to provide the possibility of obtaining enriched carnallite from potash ores with a content of 1-10% MgCIj while simultaneously producing potassium chloride.
Сущность изобретени заключаетс в том, что после выщелачивани MgClj из руды нерастворимьй оста-. ток подвергают флотационной переработке с получением KCt, а шлам от флотации обрабатьтают гор чим щелоком с извлечением из него дополнительного количества КС, который подаетс на стадию охлаждени фильтрата , полученного после выщелачивани руды, с кристаллизацией карналлита .The essence of the invention is that after leaching MgCl1 from the ore, there is no insoluble residue. the current is subjected to flotation processing to produce KCt, and the flotation sludge is treated with hot liquor to extract an additional amount of CS from it, which is fed to the stage of cooling the filtrate obtained after leaching the ore to crystallize carnallite.

Получают хлормагниевый щелок с концентрацией MgCJj 349,6 г/1000 (24,3%) в количестве 93,8 мае.ч. и сырой сильвинит в количестве 1079,3 мае.ч., KOTOjUtft перерабатывают на хлористый калий методом флотации, в результат чего получаетс 270,5 мае.ч. готового продукта с содержанием хлористог кали 95,5% и 231 нас.ч. суспензии глинистого щлама с содержанием КСе 13,2%.Example 1000 ma.h. ore composition, wt.%: KC1 31,62; NaCt 5A, 38; MgClj 2.31; CaSO1,69; but. 7.4, decompose when liquor is not saturated on MgCfj (concentration of Mac (J 21.2%). A chlorine magnesium liquor is obtained with an MgCJj concentration of 349.6 g / 1000 (24.3%) in an amount of 93.8 parts by weight. and crude sylvinite in the amount of 1079.3 math., KOTOjUtft is processed to potassium chloride by flotation, resulting in 270.5 ma.h. the finished product with a content of potassium chloride of 95.5% and 231 part.h. slurry slurry with a KSE content of 13.2%.
