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 intensity magnetic separation, high intensity magnetic-gravity separation and high intensity magnetic - reverse flotation. The test results show that the separation process of high intensity magnetic-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.
