Abstract: According to the principle of input-output, a kind of input-output model of mineral processingmetallurgy system has been proposed. Taking uncertain elements in the input-output model as bounded grey numbers, the grey input-output models have been studied. In the light of linear programming, the grey displacement input-output models were formulated, and the solutions of the models were given. The models can be used for the research of the important proportional relations and economic structure in the economic activities of other industries.A practical example was also given.
