Title:
セメントキルンダスト処理システムおよび方法
Document Type and Number:
Japanese Patent JP2013539410
Kind Code:
A
Abstract:
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.
