A method for suppressing aggregation of metal raw materials, a method for preventing blockage, a method for producing smelted metal, and an agent for suppressing aggregation of metal raw materials.

摘要

PROBLEM TO BE SOLVED: To provide a novel aggregation inhibition method of a metal raw material capable of inhibiting aggregate of the metal raw material easily, an obstruction inhibition method, a manufacturing method of a purified metal and an aggregation inhibitor of the metal raw material.SOLUTION: An aggregation inhibition method of a metal raw material has a process of adding a liquid where a polymer containing (meth)acrylic acid as a monomer unit and having weight average molecular weight of 7000000 or less to the metal raw material. An obstruction inhibition method is an obstruction inhibition method of a locations of which obstruction is inhibited during transportation of the metal raw material and the aggregation inhibition method of the metal raw material is conducted by that the metal raw material reaches the locations to be obstructed. A manufacturing method of purified metal has a process of inhibiting obstruction of locations of which obstruction is inhibited by the obstruction inhibition method and a process of obtaining target metals from the metal raw material. A aggregation inhibitor consists of a polymer containing (meth)acrylic acid as the monomer unit and having weight average molecular weight of 7000000 or less.SELECTED DRAWING: None
