Abstract
1. Способ переработки нефтьсодержащего лейкоксенового флотоконцентрата, включающий восстановительный обжиг, измельчение, сульфатизацию, разложение и выщелачивание, отличающийся тем, что предварительно отгоняют нефтяную фракцию в атмосфере инертного газа при температуре 800°С в течение 50-60 мин. ! 2. Способ по п.1, отличающийся тем, что в качестве восстановителя при обжиге используют нефтекокс после отгонки нефтяной фракции. ! 3. Способ по п.1, отличающийся тем, что восстановительный обжиг проводят при температуре 1100-1150°С в течение 50-60 мин. ! 4. Способ по п.1, отличающийся тем, что при сульфатизации используют олеум, содержащий 19-24% свободного серного ангидрида (SO3) при температуре 150°С в течение 50-60 мин. ! 5. Способ по п.1, отличающийся тем, что выщелачивание лейкоксенового концентрата проводят водой при Т:Ж=1:5 в течение 50-60 мин при температуре 90-95°С. 1. A method for processing oil-containing leucoxene flotation concentrate, including reduction roasting, grinding, sulfatization, decomposition and leaching, characterized in that the oil fraction is preliminarily distilled off in an inert gas atmosphere at a temperature of 800 ° C for 50-60 minutes. ! 2. The method according to claim 1, characterized in that petroleum coke is used as a reducing agent during roasting after distillation of the oil fraction. ! 3. The method according to claim 1, characterized in that the reduction firing is carried out at a temperature of 1100-1150 ° C for 50-60 minutes. ! 4. The method according to claim 1, characterized in that the sulfatization uses oleum containing 19-24% free sulfuric anhydride (SO3) at a temperature of 150 ° C for 50-60 minutes. ! 5. The method according to claim 1, characterized in that the leucoxene concentrate is leached with water at S: W = 1: 5 for 50-60 minutes at a temperature of 90-95 ° C.
