PURPOSE: A residual mixed ore placing method in a storage tank is prevent mixed ore from whose component changes in the middle of a pile while stacking the residual mixed ore regardless of the mixed ore residual amount in a storage tank. CONSTITUTION: A residual mixed ore placing method in a storage tank comprises the following steps. Whether a loader(30) is arrived in a standard location or not is confirmed, where the time while the loader moves to a head(B) or a tail(A) of a pile(50) from the standard location and the time while blending material moves to the head or the tail of the pile from a quantitative extractor(10) are same. The residual amount of the blending material in a storage tank(20) of the quantitative extractor is confirmed at the standard location. If the residual amount of the blending material is less than the standard value, the residual amount of the blending material is controlled by controlling the quantitative extractor. |
