Abstract

Abstract: The process mineralogy of a copper-molybdenum mixed concentrate in Tibet was studied by means of chemical analysis， microscopic analysis and MLA analysis.The research shows that the mixed concentrate contains 19.00% copper and 0.38% molybdenum， and both copper and molybdenum mainly exist in the form of sulfide. Pyrite， chalcopyrite and bornite are the main minerals in the mixed concentrate， with molybdenite present at a content of 1.0%.The grinding fineness of the mixed concentrate is extremely fine， and the degree of dissociation of molybdenite is excellent. Additionally， a small part of molybdenite exists in coexistence with chalcopyrite and pyrite.The research results provide theoretical guidance for on-site copper-molybdenum separation and transformation.

Key words: copper-molybdenum mixed concentrate; process mineralogy; copper minerals; molybdenite
