| 本発明は、硫化鉱石中の硫化鉱物のバクテリアなどによる酸化を抑制することにより、硫化鉱石から重金属成分が溶出するのを防止し、ストックパイルに堆積された硫化鉱石を処理する際に、浮選成績が低下することを緩和する。また、ストックパイルや廃石堆積場から発生する酸性廃水の処理を容易にする。そのため、ストックパイルや廃石堆積場に堆積された硫化鉱石に、カルボキシル基を含む有機酸を主成分とし、植物性ポリフェノール類を含有する抗酸化剤を添加することによって、硫化鉱石中の硫化鉱物の酸化を抑制する。 | ||||||

| 60 | METHOD FOR REMOVAL OF UNBURNED CARBON CONTAINED FLY ASH | EP06834398.7 | 2006-12-11 | EP1970135A1 | 2008-09-17 | MATSUO, Kazuyoshi; ABE, Kazuo; SUZUKI, Takao; SAITO, Shinichiro |
Disclosed is a method for removal of an unburned carbon contained in a fly ash material. The method comprises the steps of: adding water to the fly ash to prepare a fly ash slurry; shearing the fly ash slurry using an agitating blade that can rotate at a high speed to generate an active energy on the surface of an unburned carbon by the shearing force, thereby imparting lipophilicity to the unburned carbon; and adding a collecting agent and a foaming agent to the slurry containing the lipophylized unburned carbon to cause the attachment of the collecting agent to the lipophylized unburned carbon, and at the same time, causing the attachment of the unburned carbon having the collecting agent attached thereto an air bubble to separate the unburned carbon by flotation. |
