Comprehensive Recovery Process Test of a High Silicon Coarse Iron Tailings
In order to efficiently recover and utilize the valuable minerals in a coarse iron tailings,a comprehensive recovery process test is carried out on the basis of the study of ore properties.The test results show that the combined process of mud sand classification-medium magnetic iron separation-grinding and cleaning-high intensity magnetic impurity removal-flotation refining-acid leaching purification-sand wash-ing classification can produce iron concentrate with TFe grade of 61.25%and TFe recovery rate of 57.69%,coarse-grained quartz sand concentrate for high-quality glass with SiO2 content of 99.72%and Fe2O3 con-tent of 0.039%,fine-grained quartz sand for chemical industry with SiO2 content of 98.97%and Fe2O3 con-tent of 0.127%,cement or aerated brick with SiO2 content of 74.31%and TFe grade of 27.71%.It provides a scientific and reasonable technical basis for the comprehensive recovery and utilization of this type of iron tailings.
