this industrial scale study compares two grinding circuits operating in an iron ore process with a production capacity of 12 million tons per year. the plant has three identical parallel lines, all fed from the same feed pile. each line has an independent grinding circuit, with two ball mills
called hot metal. in direct reduction, iron remains in solid state and the product is the so-called direct reduced iron (dri). generically, the iron ore products for ironmaking can be classified as shown in table 1 . pellets are balls formed by rolling moist concentrates and fines iron ores of different mineral-
beneficiation of iron ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice.this also applies to iron ores of the non-magnetic type which after a reducing roast are amenable to magnetic separation. all such plants are large tonnage operations treating up to 50,000 tons per day and ultimately requiring grinding as fine as minus 500
the effect of metallic iron fines on froth flotation of a sulfide ore was examined by comparing the flotation results with and without iron fines present in the flotation feed. mild steel and ceramic laboratory ball mills were used to grind 600 g sulfide ore charges. the mild steel ball mill generated approximately 4.6 g of iron fines (0.8% of the ore charge mass) when grinding to a product
