A powder property-modifying method is used when handling a water-containing bulk material including a mineral ore, coal, and limestone, and includes adding an active component of a chemical agent whose main component is at least one selected from a polymer flocculant, an inorganic flocculant, and a polymer water absorption material, in an amount of 0.001 to 0.07% by mass with respect to the mass of the bulk material, in which water inside the bulk material is retained in a bridge structure formed between the chemical agent and a powder composing the bulk material. Another method is a production method for a water-containing bulk material that is transported via at least one selected from a vessel, a transporter vehicle, a loading heavy machine, a delivering heavy machine, a conveyor belt, and a storage tank. This production method includes modifying such water-containing bulk material with the above modifying method.
