一、前言钼精矿是提取钼、铼的主要工业原料。国内外从钼精矿生产氧化钼块、钼铁、钼酸铵并由淋洗液提取铼的方法是传统的氧化焙烧法。该法焙烧的物理化学过程有如下缺点:产生 SO_2;在焙烧温度下,MoO_3已部分挥发;有 MoS_2与 MoO_3生成 MoO_2和 ReS_2与 Re_2O_7同 MoO_3与 MoS_2生成ReO_3和 ReO_2的付反应;含铜、铅、铋等低熔点金属多的钼精矿易结块等,由此 First, the preface Molybdenum concentrate extraction of molybdenum, rhenium’s main industrial raw materials. At home and abroad from molybdenum concentrate production of molybdenum oxide block, molybdenum iron, ammonium molybdate rhenium extraction method is the traditional oxidation roasting method. The roasting physicochemical process has the following disadvantages: SO2 is generated; MoO3 is partially volatilized at the calcination temperature; MoO2 and MoS3 are formed with MoO2 and ReS2 and Re2O7 with MoO3 and MoS2 to form ReO3 and ReO2; copper and lead , Bismuth and other low-melting-point metal molybdenum concentrate easy agglomeration, and so on
