Способ флотационной очистки магнетитовых концентратов от серы

Использование: обогащение полезных ископаемых, может быть использовано при очистке магнетитовых концентратов от серы. Способ включает измельчение, кондиционирование с кислотой, ионогенным серосодержащим собирателем, реагентом-модификатором и флотацию с выделением сульфидов в пенный продукт. В качестве реагента-модификатора используется композиция на основе изоалкенилацетиленовых спиртов C₈-C₁₀ общей формулы RCH=CR'С_≡ СС(СН₂R'')(СН ₃)ОН, имеющая следующий состав (мас.%): изоалкенилацетиленовый спирт C₈-С₁₀ общей формулы RCH=CR'С_≡ СС(СН₂R'')(СН ₃)ОН - 80,0-99,0%, диизоалкенилацетилены C ₈-C₁₀ общей формулы RCH=CR'C_≡ CC(CH₂R'')=CHR''' - 0-20,0%, α-ацетиленовые третичные Y-диолы C₈-С₁₀ общей формулы (RCH₂)(СН ₃)С(ОН)С СС(СН₂R'')(СН ₃)ОН - 0-5,0% (R=H, СН₃; R'=СН ₃, С₂Н₅; R''=H, СН₃; R'''=H, СН ₃), ингибитор радикальной полимеризации - 0-1,0%.
