一前言在有色金属硫化矿中,辉钼矿是最易浮选的矿物之一,这与其晶体结构的内在特点有关。辉钼矿多呈六方层状或板状结构,磨碎时主要沿层面间碎裂解离,此鳞片状解理面具有自然疏水性,不易被氧化,所以可浮性好。但是另一方面,由于此硫化钼精矿性质稳定不容易氧化,直接冶炼比较困难,通常是先经氧化焙烧脱硫转变成三氧化钼后再湿法冶金处理;若直接加压碱浸或氧压酸浸则需使用高温加压浸取设备。
A preface In non-ferrous sulfide ore, molybdenite is one of the most flotation minerals, which is related to the inherent characteristics of its crystal structure. Molybdenite mostly hexagonal lamellar or plate-like structure, mainly broken along the ground layer of gravel dissociation, the scaly cleavage surface with natural hydrophobicity, not easy to be oxidized, so flotation good. However, on the other hand, as the molybdenum sulfide concentrate is not easily oxidized due to its stable properties, direct smelting is more difficult. Generally, it is converted to molybdenum trioxide by oxidation and roasting, and then hydrometallurgically treated. If directly pressurized with alkali or oxygen pressure Acid leaching is required to use high temperature and pressure leaching equipment.
