1. Introduction. Iron and manganese are important alloy metals that are widely used. Of these, 90% of manganese ore resources are used in the iron and steel industry in the form of manganese ferroalloy and electrolytic metal manganese products, and the remaining 10% of manganese ore resources are used in fertilizers, feeds, and …
With the rapid development of iron and steel industry, the reserves of high-quality iron ore resources are gradually decreasing, resulting in an increase in the proportion of complex refractory iron ore reserves [[1], [2], [3]]. China has 84.8 billion tons of iron ore resources. However, 97.5% of iron ore resources belong to low-grade iron …
Iron ore beneficiation is the process of improving the quality of iron ore by removing impurities and increasing its iron content. It is necessary to reduce alumina and silica in the feed. The process improves the chemical, physical, and metallurgical characteristics of the ore to make it a more desirable feed for iron-making furnaces.
3. Commercial chromite ore beneficiation processes Pure chromium is difficult to produce since it is readily contaminated by many other elements. Huge quantity of raw chromite ore is being mined and beneficiated in various chrome ore beneficiation plants throughout the world to cater the customized needs of various ferro alloy plants.
