Iron and Steel Converting by-products to feedstock Steele

The homogenous blend of iron oxide fines and fine carbon particles have driven a 20%-plus reduction in coke rates. The briquettes’ carbon content has reduced the need for imported carbon from Australia for both the mill and its customer’s mill, while improving the performance of sinter strands (stiff extrusion removes the fine materials that cause problems with sintering).

Iron ore pricing explained Metal Bulletin

Most steel mills use a blend of different grades of ore, and a mix of sinter, lumps and fines, but the quality requirements depend on the circumstances and availability. For example, ore used in the direct-reduction process to make direct-reduced iron (DRI) or hot-briquetted iron (HBI) destined for melting in an electric-arc furnace (EAF) needs to be of much higher grade than that fed into a blast furnace.

Iron ore Wikipedia

The two main methods of recycling iron from iron ore tailings are magnetizing roasting and direct reduction. Magnetizing roasting uses temperatures between 700 and 900 °C for a time of under 1 hour to produce an iron concentrate (Fe 3 O 4) to be used for iron smelting.

Roasting (metallurgy) Wikipedia

Roasting is a process of heating a sulfide ore to a high temperature in presence of air. It is a step of the processing of certain ores. More specifically, roasting is a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component. Often before roasting, the ore has already been partially purified, e.g. by froth flotation. The concentrate is mixed with other

Roasting in Metallurgy Mineral Processing & Metallurgy

Mar 18, 2017 These furnaces are from 55 to 65 feet long, holding from 6 to 9 tons, and producing about 3 tons of roasted ore per day, so that the ore remains in the furnace from two to three days. The custom there was to give the ore a long oxidising roast at a low red heat, ending in a low cherry-red heat, and then, when the ore reached the finishing floor, the temperature was slightly lowered, and the salt added.

Gold Ore Roasting Techniques

On the basis of a mill feed of 1200 tons per day, about 23 tons per day of concentrate carrying 26 to 27 per cent sulphur is roasted. The installation includes two standard 70-rabble roasters, though only one unit is currently used. A 25-hp. motor drives the complete mechanism of each roaster.

Beneficiation Wikipedia

For sulfide ores, a different process is taken for beneficiation. The ore needs to have the sulfur removed before smelting can begin. Roasting is the primary method of separating, where wood was placed on heaps of ore and set on fire to help with oxidation. 2 Cu 2 S + 3 O 2 → 2 Cu 2 O + 2 SO 2
