Abstract:
To provide a preparation method of a copper refining raw material, capable of suppressing instability of the operation of a copper refining furnace caused by drying failure of a miscellaneous raw material in a wet state.SOLUTION: A preparation method of a copper refining raw material comprising a copper concentrate and a miscellaneous raw material in a wet state includes steps of: expanding the miscellaneous raw material in a wet state in a layering state on a surface, and scattering so as to cover from above the miscellaneous raw material in a wet state, a moisture absorbent which preferably contains copper represented by flue cinder recovered from exhaust gas of a copper refining furnace, and has a particle size smaller than that of the miscellaneous raw material in a wet state; keeping for a predetermined time a state that the miscellaneous raw material and the moisture absorbent are brought into contact with each other; and mixing the moisture absorbent with the copper concentrate while disintegrating the miscellaneous raw material whose moisture percentage is lowered due to being kept.SELECTED DRAWING: Figure 1
