我矿钨精矿含磷高,是一个老大难问题。三结合试验小组通过试验后,在生产中,又经过不断改进,找到了适合我矿生产低度钨精矿的脱磷工艺流程。一、原料来源及其性质脱磷原料,系重选毛钨精矿,经过精选段脱硫后的-40目扫选精矿和细泥弹簧摇床精矿,以及皮带溜槽精矿等。原料一般含WO_3 40%左右。含P在0.4%左右,有时高达0.9以上。其主要组成:有黑钨矿、白钨矿、锆英
I mine tungsten ore high phosphorus, is a chronic problem. Three combined test group after the test, in production, and after continuous improvement, I found a mine for the production of low-grade tungsten concentrate dephosphorization process. First, the source of raw materials and their nature dephosphorization of raw materials, Department of re-election wool tungsten concentrate, after the desulfurization of the selected section of -40 mesh sweep concentrate and fine mud spring shaker concentrate, and belt chute concentrate. Raw materials generally contain WO_3 40% or so. P containing about 0.4%, sometimes up to 0.9 or more. Its main components: a wolframite, scheelite, zircon
