A method for recovery of lime sulfur wastes at processing of acid sludge – the waste of oil refinement – into asphalt concrete comprises deacidification of sulphuric acid of acid sludge to formation of plastic-viscous organic-mineral mass of bituminous cement and mineral white and its mixing with carbonate crushed stone and sand, and filling agent. The deacidification of acid sludge is realized by floured fraction of lime sulfur waste, and every other fractions of lime sulfur waste are introduced as fine aggregate and filling agent, obtained from floatation of sulfur ore at ore mining and processing mills of sulfuric combine. |
