摘要:
为了验证某难选低品位硅钙质胶磷矿选矿工艺获得合格品位磷精矿的可靠性,依据小型试验确定的“阶段磨矿-多段反浮选-磁选”联合流程的工艺参数,配置了扩大试验设备,开展了1.0 t/d的选矿扩大试验研究,连续运行72 h的累计选矿指标为:磷精矿P2O5品位33.80%,回收率80.02%,倍半氧化物含量为2.49%。扩大试验所用药剂种类少,药剂选择性较好;工艺流程简单、操作稳定,对低品位硅钙质磷矿适应性较强。
Abstract:
To verify the reliability of the processing technology obtaining qualified phosphate concentrates from a low grade silicon-calcareous collophanite ore,the equipments for pilot test were installed with the process parameters determined by the small-scale laboratory tests of the combined flowsheet of "stage grinding-multi-stage reverse flotation-magnetic separation". The pilot test was carried out at 1.0 t/d. The phosphate concentrates with 80.02% of P2O5 recovery rate,33.80% of grade and 2.49% of sesquioxide content were obtained after the continuous operation of 72 h. A few kinds of reagents with high selectivity were used in the pilot test, the technologicalprocess is simple,and the operation is stable and highly adaptable to low grade silicon-calcareous collophanite ore.
