现在通用的处理钼焙砂工艺流程是焙砂在氨水中溶解.氨溶焙烧钼的产物可使75—85%的钼(依焙砂成分不同)转移到溶液中.剩余的金属集中在氨浸渣中.因此需要对氨浸渣进一步处理以便回收剩余的金属.氨浸渣组成(%重量):Mo 15～20,其中氧化钼为 13～18;Fe 5～10:SiO_2 50～60,Cu 2～4,Ca 1～3,S(总)0.5～1.5;H_2O 10～15.浸渣中钼以正钼酸钙、钼酸铜、钼酸铁和部分未烧透的MoS_2形式存在.在选择合理的处理含钼浸渣流程时必须注意浸渣中铁的含量高,给钨钼分离带来很大困难.因此,目前所采用的钼焙砂氨浸渣补充回收钼的工艺流程可分为两类,第一类
Now common processing molybdenum calcine process is calcine dissolved in ammonia.Ammolytic roasting of molybdenum products can make 75-85% molybdenum (according to baking ingredients different) transferred to the solution, the remaining metal concentrated in the ammonia leaching Therefore, it is necessary to further treat the ammonia leaching residue to recover the remaining metal.Ammonia leaching residue composition (% by weight): Mo 15-20, of which molybdenum oxide is 13-18; Fe 5-10: SiO 2 50-60, Cu 2 ~ 4, Ca 1 ~ 3, S (total) 0.5 ~ 1.5 and H_2O 10 ~ 15. The molybdenum in the leaching residue is in the form of calcium orthomolybdate, copper molybdate, iron molybdate and partially unsolded MoS 2. When choosing the reasonable process of molybdenum-containing leaching residue, it is necessary to pay attention to the high content of iron in the leaching residue, which brings great difficulties to the separation of tungsten and molybdenum.Therefore, the technological process of supplementing and recovering molybdenum with molybdenum- Two categories, the first category
