Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route).The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.

Thus, the two factors that most affect the loss of copper to slag in the smelting stage are: matte grade; mass of slag. This means that there is a practical limit on how high the matte grade can be if the loss of copper to slag is to be minimized. Therefore, further stages of processing (converting and fire refining) are required.

Jan 18, 2017· Many people confuse gold smelting with melting. Whereas gold melting is simply heating gold to turn into a liquid form before forming gold bars, smelting is a more complex process that involves the removal of impurities from gold using heat, pressure and a number of chemicals. History of Gold Smelting . The smelting of gold is not a new process.

Role of Slag in Converter Steelmaking. The oxygen converter process is the primary steelmaking process for the production of carbon and low-alloy steels. The process is essentially an oxidizing process of refining of the high carbon hot metal (HM) to low carbon liquid steel. The oxidizing process is carried out by blowing oxygen in the converter.


A technological scheme for copper slag processing is proposed. It comprises 5 stages, namely: (i) air oxidation of the copper slag at a temperature above 800 °C for 2 …

Nov 14, 2018· Fig 1 Processing of steelmaking slag. As steelmaking slag is formed, it is in a molten or red-hot state at temperatures ranging from 1,300 deg C to 1,700 deg C. This slag is immediately subjected to the cooling process upon removal. Usually, this is performed in a cooling yard by air cooling and moderate water sprinkling.

complex processing of slag -

The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling. Virtually all steel is now made in integrated steel plants using a version of the basic oxygen process or in specialty steel plants (mini-mills) using an electric arc furnace process.

A method of processing vanadium-containing slag

Process bleed streams may contain antimony, arsenic or mercury. Large quantities of water are used for slag granulation, but the majority should be recycled. Solid wastes and sludges The smelter contributes a slag that is a dense silicate. Sludges that require disposal will result where neutralized process effluents produce a precipitate.
