  • A New Process for the Recovery of Ammonia from

    This paper describes a new method for the recovery of highconcentration ammonia from water in the form of ammonium chloride, ammonium hydroxide and ammonium carbonate The method was applied to the Solvay process, in which sodium bicarbonate is produced through the reaction of ammoniated brine and CO2 gas The Solvay effluent contains ammonia in the form of soluble ammonium chloride1 Introduction Mining industries are now faced with strict environmental regulations because of the presence of ammonia, metalloids and heavy metals in their final effluents []Examining the current legislative frameworks shows that the treatment of ammonia is gaining public concerns []Ammonia gas, NH 3, is generally resulted from the explosive mixture of ammonium nitrate/fuel oil (ANFOPragmatic strategy for the removal of ammonia from gold

  • Ammonia Leaching: A New Approach of Copper Industry

    Ammonia and ammonium salts have been recognized as effective leaching agents in hydrometallurgical processes due to low toxicity and cost, easy recovery and high selective recovery of metals New research findings on considerable advantages of leaching by these agents and elimination of problems associated with acid leaching have resulted in a new approach in the world to this methodThe ammoniasynthesis industry has become a research hotspot, because its high energy consumption and CO 2 emission exacerbate the current resource shortages and environmental pressures However, the current research on life cycle assessment (LCA) of synthetic ammonia in China is limitedLife cycle assessment of ammonia synthesis based on
