] HAN Yue-xin, LIU Lei, YUAN Zhi-tao, WANG Ze-hong, PATRICK Z. Characteristic comparison of low-grade hematite product characteristics in a high pressure grinding roller and jaw crusher [J]. Minerals &......
of residue is dominated by Fe (30%–50% Fe2O3) and its mineralogy often approximates to 10%–30% goethite, 10%–30% hematite, 2%–20% calcite, 0–5% gibbsite, 2%–15% anatase, 3%–10% quartz and 5%–20% sodalite... in goethite, hematite and sodalite in surface layers were noted by SANTINI et al [82] after 10–20 years. Due to the dominance of iron oxides, and the absence of high-activity clay minerals, bauxite residue......

Experimental study on cationic reverse flotation by flotation column of a magnetite and hematite mixed iron ore[J]. Multipurpose Utilization......
was composed of pyrrhotite, pyrite, magnetite, hematite, limonite, siderite and a small amount of chalcopyrite. Tongguanshan tailing pond was discarded in 1991, from which samples B and C were collected......
as limestone and FeO was added as a combination of metallic iron and hematite. 400 g of the targeted composition was weighed, mixed and transferred in an Al2O3 crucible (270 mL). The Al2O3 crucible......

to qualitatively analyze the mineral phases at room temperature (Fig. 1(a)). The analysis results showed that major minerals are magnetite, talc, actinolite, antigorite, pyrite and hematite. The sulfides......
for these ratios being indeterminate. Most importantly, unstable ferrihydrite could transform to goethite or hematite under different conditions [28], whereas detectable ferrihydrite was the initial product......
along with epidote in field of calcite and quartz. Among the skarn minerals, we can point to magnetite, hematite, malachite, pyrite and chalcopyrite. 4.1.3 Zagher hornfels Hornfelses are observed......
on and the main ore minerals were chalcopyrite, chalcocite, bornite, molybdenite, magnetite, hematite and so on [64]. 2.2 Metallogetic model for Kaerqueka The metallogenic belt was formed in the eastern Kunlun......
