簡介:"礦物硫化物及硫鹽輝鉬礦Molybdenite Sulfides and SulfosaltsMolybdenite is mainly composed of molybdenum and sulfur. It usually contains rhenium and selenium, and small amounts of gold and silver sometimes.It is of leaden color and low hardness. Complete cleavage on the underside is distinctive. Even though molybdenite is very similar to graphite in terms of their cleavage and hardness, it has a by far bigger specific gravity.Molybdenite, when on the Earth's surface, weathers into yellow Ferrimolybdite (Fe2(MnO4)3.8H2O), which is an important signal to molybdenum deposit.Molybdenite is the major source of molybdenum and rhenium.主要由鉬和硫所構成,常含有錸(Re)和硒(Se),偶爾也含有少量的金和銀。 鉛灰顏色、低硬度、底面解理極完全為其特徵。雖在晶形、解理、硬度和產狀等方面與石墨十分相似,但比重卻較石墨要大得多。 在地表條件下,會風化轉變為黃色的鐵鉬華(Ferrimolybdite, Fe2(MnO4)3.8H2O)。而鐵鉬華也是尋找鉬礦床的一種重要標誌。 輝鉬礦為提煉鉬和錸的最主要礦物原料。"
