In high-phosphorus iron ore deposits, the phosphorus is present either as discrete phosphate minerals (e.g., apatite) or as a phosphate in iron oxide and oxyhydroxide minerals in the ore. High impurity levels of silicon, aluminum, and sulfur in the ores are usually due to the presence of mineral impurities (e.g., quartz, kaolinite, pyrite, and ...
Vale is the largest iron ore producer in the world. Since the 1970s, Vale has been using reverse cationic flotation to remove siliceous impurities from its iron ores. Whilst this flotation process has operated effectively for many years, it suffers from the problems of high reagent costs and high metal loss.In 2010, CSIRO investigated the use of a reverse anionic flotation process for Vale ...

Brazil heavyweight Vale is the only one that can deliver a 65 per ...
The iron ore, along with coke and limestone, is fed into the furnace from the top. The intense heat generated by the combustion of coke melts the iron ore, resulting in the production of molten pig iron. ... Sponge iron, on the other hand, has a higher iron content and lower impurity levels compared to pig iron. It contains around 90% to 94% ...
Simultaneously, the iron grade and level of SiO2+Al2O3 impurity in the iron ore product from reverse fl otation of the low-grade iron ore with DTAB collector reached 60.0 mass% and 4.4 mass%, which are acceptable levels for ironmaking.
