Jindal Steel and Power’s MIDREX® Direct Re-duction Plant (JSPL-Angul) commenced operation using only syngas produced by a dedicated coal gasification plant. This is a first of a kind project that demonstrates that gas-short regions also can produce DRI. Also in India, the MIDREX ® Plant at the JSW Dolvi Works in Raigad, Maharashtra, began
Hot direct reduced iron (HDRI) is DRI that is transported hot, directly from the reduction furnace, into an electric arc furnace, thereby saving energy. The direct reduction process uses pelletized iron ore or natural "lump" ore. One exception is the fluidized bed process which requires sized iron ore particles.

It is this continual improvement that made the MIDREX ® Process the world's leading technology for the direct reduction of iron ore. For more than two decades, MIDREX ® Plants have produced 60 percent or more of the world's DRI each year and we continue to develop some of the industry's most efficient and successful technologies.
Mar 16, 2013 Fig 1 DRI process principle. Major DRI production processes are either gas based or coal based. Feed material in a DRI process is either iron ore sized to 10 to 30mm or iron ore pellets produced in an iron ore pellet plant. In the gas based plant the reactor, the reduction reaction takes place is

Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

This is another article in my series on the smelting of metals, this one focusing on the smelting of copper. We shall begin by looking at the mining and processing of the copper bearing ore, followed by an examination of an established and a modern copper smelting process. Mining for Copper

In most cases the DRI plant is located near natural gas source as it is more cost effective to ship the ore rather than the gas. India is the world’s largest producer of direct-reduced iron, a vital constituent of the steel industry. Many other countries use variants of the process, so providing iron for local engineering industries. Problems
Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific
Part Four Competitiveness ducing copper: the direct and indirect costs in-curred in mining, concentrating, smelting, and refining copper. They include transportation to the mill, smelter, and refinery, and metallurgical copper projects, and dramatically affect the

criteria for balance of plant (BoP) i.e. coal handling plant (CHP), ash handling plant (AHP), water treatment system, etc. is being taken up in the next phase. I am glad that the standard technical specification for Main Plant Package has been finalized by the Committee.
Because of this companies such as Magnetation, Inc., have started reclamation projects where they use iron ore tailings as a source of metallic iron. The two main methods of recycling iron from iron ore tailings are magnetizing roasting and direct reduction.
Gold refining by solvent extraction—the Minataur™ Process by A. Feather*, K.C. Sole*, and L.J. Bryson* Synopsis The Minataur™ Process (Mintek Alternative Technology for Au Refining) is a novel route for the production of high-purity gold using solvent extraction. Following the successful demonstration of the process on a pilot-plant scale
EVRAZ ZSMK and Paul Wurth successfully finalized the first phase of a stepwise technical upgrade of the hot blast stoves plant at ZSMK Works’ No. 2 blast furnace in Novokuznetsk, West Siberia.Back in 2014, Paul Wurth won a tender for engineering a complete new hot blast generation plant in preparation of the project.

12.3 Primary Copper Smelting 12.3.1 General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg)
The sponge iron process. The longest established of these processes is the sponge iron process, the leading example of a family of processes involving solid state reduction of an oxide. In the process, selected magnetite (Fe3O4) ore is mixed with coke and lime and placed in a silicon carbide retort.
The Bayer process dissolves the aluminium component of bauxite ore in sodium hydroxide (caustic soda); removes impurities from the solution; and precipitates alumina tri hydrate, which is then calcined to aluminium oxide. A Bayer Process plant is principally a device for heating and cooling a large re circulating stream of caustic soda solution.
Figure 1: Overview of copper production Benefication process Figure 2: Overview of a typical beneficiation process at a concentrator Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine (0.5 1 %

in dry scrubber systems for fluoride abatement at aluminum reduction plants. There is a clear trend toward the production of increased quantities of sandy alumina. In Russia, due to a lack of bauxite, a process using nepheline as feed-stock has been used to produce alumina. Essentially the technique consists of sintering a nepheline ore, or
