Experimental research on beneficiation process for a specularite ore

An iron ore contains specularite and hematite which are its main iron minerals. And its main gangue minerals are specularite, part of the clay material and a small amount of quartz.Tests are made on the ore by adopting processes including gravity separation, high magnetic separation,HIMS-gravity separation and HIMS-reverse flotation.The test results show that the separation process of HIMS-reverse flotation can obtain an iron concentrate grading about 66.62% at a recovery of 58.38％ from an iron ore assaying around 35.00% iron,rather good metallurgical performances.
