Description
Эффективное обогаол,ение фосфоритовых и апатитовых руд встречает значительные трудности из-за присутстви в рудах карбонатных минералов.Effective annealing of phosphate and apatite ores encounters considerable difficulties due to the presence of carbonate minerals in the ores.
Трудность флотационного разделени кальциевых минералов определ етс наличием в кристаллической решетке одного и того же катиона кальци , который, по мнению многих исследователей, химически взаимодействует с пол рной группой собирателей анионного строени и обусловливает близость флотационных свойств минералов. Поэтому подбор селективно действующего собирател дл флотационного разделени кальциевых минералов вл етс весьма сложной задачей. Однако в практике обогащени подобных руд известен и прием использовани селективного подавател . При этом в качестве селективного нодавател фосфоритов (апатита) известно применение кремнефтористого натри . Отличием предлагаемого способа вл етс использование в качестве селективно действующего подавател кремнефтористого магни , который, как показали исследовани , вл етс более эффективным.The difficulty of the flotation separation of calcium minerals is determined by the presence in the crystal lattice of the same calcium cation, which, in the opinion of many researchers, chemically interacts with the polar group of anionic collectors and determines the similarity of the flotation properties of minerals. Therefore, the selection of a selectively active collector for the flotation separation of calcium minerals is a very difficult task. However, in the practice of enriching such ores, the use of a selective feeder is known. At the same time, the use of sodium silicofluoride is known as a selective phosphate rock aggregate (apatite). A distinctive feature of the proposed method is the use of magnesium fluorofluoride as a selectively active feeder, which, as studies have shown, is more effective.
