Description

technical field [0001] The invention belongs to the technical field of ore dressing, relates to the technical field of flotation of colloidal molybdenum minerals, and in particular relates to an environment-friendly collector of colloidal sulfur molybdenum minerals, a preparation method and an application. Background technique [0002] Molybdenum is a silver-white metal, hard and tough, with a high melting point and relatively high thermal conductivity. It does not react with air under normal temperature. Because molybdenum has the advantages of high strength, high melting point, corrosion resistance and wear resistance, it is widely used in the fields of steel, petroleum, chemical industry, electrical and electronic technology, medicine and agriculture, and is a strategic metal resource in the 21st century. Molybdenum mainly comes from molybdenite, but with the continuous mining of resources, the demand for the development and utilization of other molybdenum resources is be...
