Document Type and Number:
Japanese Patent JP7116952
Kind Code:
B2
Abstract:
To provide a processing method of particulate matter which can be performed at a low cost with a simple operation without producing excessive waste.SOLUTION: A processing method of particulate matters includes an agent adding process (step S1-a) of causing an agent to include an aqueous solution which contains divalent iron ions and trivalent iron ions and adding the agent to the particulate matters, a mixing process (step S1-b) of mixing the agent and the particulate matters and a heating process (step S1-c) of heating a mixture of the particulate matters and the agent, and further includes a process (step S1) of preparing/adsorbing a ferromagnetic body consisting essentially of a magnetite onto a surface of the particulate matters and a classification process (step S2) of classifying the particulate matters which prepare and adsorb the ferromagnetic body consisting essentially of the magnetite onto the surface thereof according to magnetic screening.SELECTED DRAWING: Figure 1
