EM-501对高磷鲕状赤铁矿的脱磷效果

配制了一种新型脱磷捕收剂EM-501,并采用该捕收剂对重庆桃花高磷鲕状赤铁矿和湖北官店高磷鲕状赤铁矿的脱泥后产品进行了反浮选脱磷试验。桃花高磷鲕状赤铁矿的脱泥后产品经EM-501一粗一精二扫脱磷反浮选,P含量从0.82%降到0.081%;官店高磷鲕状赤铁矿的脱泥后产品经EM-501一粗一精一扫脱磷反浮选,P含量从0.89%降到0.21%。试验结果证明,EM-501对含磷矿物捕收能力强,并具有较好的选择性,是高磷鲕状赤铁矿的有效脱磷捕收剂。

Dephosphorization Efficiency of EM-501 on High-phosphorus Oolitic Hematite

A new dephosphorization collector EM-501 is prepared and used in the reverse flotation tests of dephosphorization for de-sliming products of high-phosphorus oolitic hematite from Chongqing Taohua and Hubei Guandian.For Taohua high phosphorus oolitic hematite，P content decreased to be 0.081% from 0.82%，with EM-501 as collector by the process of one-roughing，one-cleaning and two-scavenging after de-sliming.For Guandian hematite，P content dropped to be 0.21% from 0.89% by the reverse flotation process of one-roughing，one-cleaning and one-scavenging with EM-501 as collector.The experimental results confirmed that EM-501 had a collecting ability for phosphorus minerals with a good selectivity.So it is an effective dephosphorization collector for high-phosphorus oolitic hematite.
