Iron Concentrate

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.

Viable Solution

The present investigation deals with the sinterability of Goa (India) iron ore having high Fe (65.2%) content. The sinter basicity (CaO/SiO2) and its MgO were varied in the 2.0 to 2.5 and 1.5 to 3.0 range. The effect of process variables on the quality parameters of sinter namely, tumbler index (TI), reduction-degradation index (RDI) and reducibility index (RI) as well as the productivity of sinter was studied. The studies have shown that the consumption of coke (C: 74%) was inter-influenced by the sinter basicity and its MgO content. Increasing the solid fuel consumption was not a viable solution to improve TI and RI simultaneously. The content of coke in the mix could be reduced to as low as 4% through `low temperature sintering? at the balanced return fines recirculation (~ 33 wt. percent). The sintering indices in terms of productivity of sinter and its quality improve quite significantly at a higher sinter basicity (CaO/SiO2 ~ 2.5) and its lower MgO content (1.5%).
