摘要： A process for treating acid mine drainage containing heavy and base metals and soluble contaminants is provided. In one embodiment, at least a metal cation is added to the acid mine drainage at a pre-select pH to form insoluble heavy and base metal complexes. After the removal of the heavy and base metal complexes, the pH is raised to the alkaline range. Following removal of base metal hydroxides and gypsum, membrane filtration is employed to generate a treated membrane permeate having a reduced concentration of heavy and base metals and soluble contaminants, and a membrane reject stream containing a concentrated brine. The concentrated brine is further treated with additional lime and at least an aluminum salt to remove remaining soluble contaminants, thus producing a treated water stream with reduced levels of contaminants. Carbonation with CO2 is employed at the end of the process to neutralize flows and further precipitate residual aluminum and calcium salts.

摘要： A process for treating spent catalyst containing heavy metals, e.g., Group VIB metals and Group VIII metals is provided. In one embodiment after deoiling, the spent catalyst is treated with an ammonia leach solution under conditions sufficient to dissolve the group VIB metal and the Group VIII metal into the leaching solution, forming a leach slurry. After solid-liquid separation to recover a leach solution, chemical precipitation and solids repulping is carried out to obtain an effluent stream containing ammonium sulfate (Amsul), ammonium sulfamate, Group VB, Group VIB and Group VIII metals. Following sulfidation, the Group VIII metal is fully removed and Group VB and Group VI metals are partially removed from the Amsul stream. In the additional steps of oxydrolysis and iron precipitation, an effective amount of ferric ion at a pre-select pH is added to form insoluble complexes with the Group VB and Group VIB metals, which upon liquid-solid separation produces an effluent ammonium sulfate stream containing less than 10 ppm each of the Group VB and Group VIB metals.
