当矿浆pH值为6.82时,捕收剂用量的变化在两个体系中对磁黄铁矿浮选效果的影响不大;
When the pH value was 6.82 , the change in the collector dosage had little effect on the flotation of pyrrhotite in both systems .
-
矿浆pH值的变化对矿物可浮性影响较大,两个体系下均是在碱性越强的矿浆中磁黄铁矿的回收率越低,矿浆电位值也随着矿浆pH值增大而降低;
For both systems , the stronger the alkalinity of the pulp , the lower the recovery of pyrrhotite and the pulp potential value was reduced with the increase in pulp pH value .

磁黄铁矿的天然可浮性较差,在pH在4.5-6的范围内磁黄铁矿有一定的可浮性,但当矿浆pH值大于8以后它将很难在没有活化剂的条件浮起。
Pyrrhotite has poor floatability . When the pulp pH value range is from 4.5 to 6 , pyrrhotite can be floated partly . But when the pulp pH value is above 8 , pyrrhotite cannot be floated unless activators are used .

磁黄铁矿的Ni、Co、Cu含量与S正相关,说明微量重金属元素与S具有同源的关系,由于地幔去气伴随S而进入下地壳。
Ni , Co and Cu contents in pyrrhotite have a positive correlation with S , indicating that trace heavy metal elements are derived from the same source as sulfur because of degasification of the upper mantle and sulfur entrance into the lower crust .
