Outotec DC Smelting Plant Use a costefficient, sustainable, and compact solution for ferroalloys processing. Outotec's direct current (DC) smelting furnace can be used for direct smelting of fine ores, even those with highly variable chemical or mineralogical compositions, as well as for recycling challenging byproducts such as steel dust.
Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned. Included in this article also is a discussion of the mining of iron and of its preparation for smelting. Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive
Currently, the closest scrap yard to me pays 195 perton, or per 2,000 pounds for ferrous metals. This breaks down to approximately 10 per 100 pounds of metal. The price that scrap yards pay fluctuates with worldwide supply and demand and can cha...
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil ".
It's all about volume. In the iron ore industry, you want the largest possible throughput of iron ore through your processing equipment. That's why you need the most reliable and proven equipment that never lets you down, even though it handles large tonnages every day of the year.

in phytomining, plants can absorb copper ions from lowgrade copper ore as the grow. This could be on slag heaps of previously discarded waste from the processing of copperrich ores. Then the plants are burned and the metals can be extracted from ash. The copper ions can be "leached" (dissolved) from the ash by adding sulphuric acid.
