East tianshan gobi super-large molybdenum material bed composition and mineral separation new process

Through the argument of Xinjiang Hami Tianshan orogenic belt east segment eastern gobi super-large molybdenum material bed composition and mineral separation new technology, reveals the complexity of mineral deposit composed substance and processing properties, obtain the following knowledge: 1) The host rocks are mainly metasandstone、metamorphic sandy shale and metamorphic shale sand, ore mainly with multiple complex construction characteristics, these factors on ore adverse effects of technology; 2) adopted the flotation process: for a Float second sweep seven sift; 3) roughing: grinding adopt-200 mesh 70% conditions, lime dosages 500g/t, sodium silicate dosage 0g/t is the best value, GR-713 dosage 150g/t, 2 oil 75g/t, by the amount of raw materials by dressing recovery and grade are the best solution; 4) selected: two sections of grinding fineness conditions for-400 mesh 95%, sodium sulfide dosage 50g/t; 5) closed-circuit test: a period using-200 mesh 70%, two sections of using-400 mesh 95%, dressing total result is: refined mineral rate 0.24%, grade 45.85%, recovery 86.4%; tailing productivity.99.76%,grade 0.017%, recovery 13.6%. Molybdenum concentrate fit molybdenum concentrate national quality standard of the grade 2 third kind, suggest various processing method and proportion of materials are appropriately, ore processing properties for easy to choose performance comprehensive evaluation.
