Description
, Недостатком известного способа получешш трехокпсп мо ибдена иутем возгонки се из обожженного молибде1101зого концентрата нри 1300- 1400 Я1 л етс относительно невысокое нзнлечснне металла. Причина этого заключаетс в том, что в обожженном молибденовом концентрате только небольша часть молибдена находитс is И1де свободной трехокнсп , котора сра нлтелыю легко может быть возогиана. Напротив, больша часть молибдена содержитс в форме соедипен1пт окиси молибдена с другими окис ми и в виде низших окислов мо.тгт бдеиа или их соедиiieHUH , 3 которых трехокись молибдена не может 6i)iTb отогнана обычными методами.The disadvantage of the known method is a three-way mothbden and the sublimation of the calcined molybdenum concentrate from 1300-1400 H1 is relatively low in terms of metal. The reason for this is that, in the calcined molybdenum concentrate, only a small part of the molybdenum is found i1de free of trichoxins, which can easily be ignited by the center. In contrast, most molybdenum is contained in the form of compound molybdenum oxide with other oxides and in the form of lower oxides moth bdeia or their compound HUH, 3 of which molybdenum trioxide cannot 6i) iTb distilled by conventional methods.

In order to further increase the yield of molybdenum trioxide, oxidation of 1processing o-product is carried out by passing over it (or through it) non-continuously (or periodically) oxygen or its mixture with other gases in such quantities that the furnace maintains the desired degree of vacuum, which gives the possibility of obtaining pure molybdenum trioxide with a high percentage of molybdenum extraction from concentrate (about 95%).
