%X The present invention belongs to the field of mineral processing technology, and particularly relates to a gangue mineral combination inhibitor, its preparation method, and application. The present invention provides a combination inhibitor of gangue minerals, comprising the following components in terms of mass fraction: 1-7 parts of sodium phytate; 40-120 parts of sodium hexametaphosphate. In the combination inhibitor of gangue minerals provided by the present invention, sodium phytate and sodium hexametaphosphate can achieve the purpose of co adsorption of gangue minerals, and can suppress the foaming and flotation of gangue minerals during the flotation process with a small amount of dosage; Meanwhile, the gangue mineral combination inhibitor provided by the present invention has no inhibitory effect on scheelite and will not affect its flotation. The test results show that the gangue mineral combination inhibitor provided by the present invention has a good inhibitory effect on gangue minerals in the flotation process of scheelite, and does not have an inhibitory effect on scheelite. It has excellent inhibitory effect on gangue minerals even under the condition of less dosage of gangue mineral combination inhibitor in the flotation process.
