Beneficiation of a low-grade, hematite-magnetite ore in China

May 01, 2014  In China, most reserves of rich iron ores have now been depleted and sustainable development of low-grade iron ores has become a critical discussion topic in the mining industry today. The aim of this study was to evaluate the applicability of beneficiating a low-grade, hematite-magnetite ore (assaying 18.64% Fe) for subsequent utilization. In this study, process mineralogy and beneficiation ...

Advances of Iron Ore Beneficiation in China

China has large amounts of iron ore reserves, but iron ore in China, with low-grade, small disseminated particles and many other associated minerals, is difficult to dress. In recent years, with the fast development of China's steel industry, the demand for iron ore has increased markedly. The new technologies in iron ore dressing in China are very effective in processing haematite and other ...

Beneficiation of Low-Grade Haematite Ores

Large tonnages of low-grade haematite ores need to be treated every day in China. One of the mineralogical characteristics of these haematite ores is that the grain size of haematite is smaller than that of quartz and is not uniform in the ores. Therefore, a flow sheet consisting of gravity concentration, low-intensity magnetic separation, high-intensity magnetic separation and reverse ...

1.1 Types of iron ore Iron ores can be classified in different ways. The most important has to do with the iron content. In many cases, ore with a total iron content of 60% to 63%, or greater, is regarded as high grade, and ore with a lower iron content is regarded as low grade. Ores are also classified as follows, according to their
