May 25, 2020· Copper slag is a by-product created during the extraction of copper from copper ore This material represents a popular alternative to sand as a blasting medium in industrial cleaning Using blasting or high-pressure spraying techniques, companies can use copper slag to clean large smelting furnaces or equipment...

Iron Ore Statistics and Information

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe) It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3) Iron ore is the source of primary iron for the world's iron and steel industri...

Iron Ore Smelting Process

The ore is loaded into a blast furnace along with measured quantities of coke and limestone Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron The slag and molten iron are tapped off from the bottom of the furnace, the slag being ....

Iron and steel

Sep 15, 2019· Pure iron is too soft and reactive to be of much real use, so most of the "iron" we tend to use for everyday purposes is actually in the form of iron alloys: iron mixed with other elements (especially carbon) to make stronger, more resilient forms of the metal including steel Broadly speaking, steel is an alloy of iron that contains up to ....

Copper extraction

The greater the iron content of the feed, the more iron that will need to be rejected to the slag for a given matte grade Similarly, increasing the target matte grade requires the rejection of more iron and an increase in the slag volume Thus, the two factors that most affect the loss of copper to slag in the smelting stage are: matte grade...
