Sistema y procedimiento de tratamiento del polvo del horno para cemento
Método para tratar polvo de horno para cemento (100) que comprende: Recibir el polvo del horno para cemento (100) de un horno para cemento; Calentar el polvo del horno para cemento (100) para separar al menos un metal pesado del polvo del horno para cemento (100) con el fin de crear una corriente de gas que contenga un metal pesado (107); Tratar la corriente de gas (107) con un fluido de tratamiento, donde el tratamiento del chorro de gas (107) con un fluido de tratamiento consiste en tratar el chorro de gas con un fluido de tratamiento que contiene al menos un sulfuro de metal alcalinotérreo; y Retirar al menos una parte de al menos un metal pesado de la corriente de gas (107).
The invention relates to a method for treating cement kiln dust comprising at least one heavy metal. The method comprises the steps of: separating the heavy metal from the cement kiln dust to create a heavy-metal-containing stream; treating the heavy metal stream with a treating fluid containing at least one of an alkaline-earth metal sulfide and an alkaline-earth metal polysulfide; and removing at least a portion of the heavy metal from the stream. Moreover, the invention relates to a method of reclaiming a desired raw material from an industrial byproduct containing mercury. The method comprises the steps of: separating the mercury from the industrial byproduct by adding sufficient kinetic energy to the industrial waste to form a stream of separated mercury and a stream containing the desired raw material; treating the stream of separated mercury with a treating fluid containing at least one of an alkaline earth metal sulfide and an alkaline earth metal polysulfide to form a particulate containing the mercury; collecting the desired raw material separately from the particulate; and collecting the particulate for subsequent handling.
