We will discuss the extraction of iron from iron ore as an example Extraction of iron Iron atoms are found in the compounds FeO Fe 2 O 3 and Fe 3 O 4 and in rocks like haematite and magnetite South Africa is the seventh largest producer of iron ore in the world Iron has been mined in South Africa for thousands of years
Get PriceExtracting copper from other ores Copper can be extracted from non-sulphide ores by a different process involving three separate stages Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution
Get PriceSome underground mines are 1 000 feet deep To remove coal in these underground mines miners ride elevators down deep mine shafts where they run machines that dig out the coal Processing the Coal After coal comes out of the ground it typically goes on a conveyor belt to a preparation plant that is located at the mining site
Get PriceStage 1 A Macerator processes ore - iron gold copper tin lead and uranium - into 2x crushed ore of the corresponding type It does not process (as of 2 6 130-ex110) ores for coal lapis diamond redstone emerald or nether quartz Crushed ore can be smelted into ingots (except for uranium)
Get PriceEnergy and Environmental Profile of the U S Mining Industry 5 1 Process Overview 5 1 1 Copper Ore Mining Copper is commonly extracted from surface underground and increasingly from in situ operations In 2000 the principal mining States in descending order Arizona Utah New Mexico and Montana accounted for 99 percent of domestic production
Get PriceFull Answer The transport of iron ore by way of railway or freight requires a highly stable infrastructure for the mining production to be economically feasible As a result the mining of iron ore has remained in the control of a few major companies Iron ore is the main ingredient in steel which makes up 95 percent of the metals used in the world per year
Get PriceThe iron ore shown to the right was excavated from Skgar a Viking-age iron-making site in Iceland The larger piece is about 2cm (less than 1in) in the long dimension Sometime about 1000 years ago someone gathered this iron ore processed it transported it to the iron smelting site but for unknown reasons never used it in a smelt
Get PriceThese include sulfuric acid oxygen iron silica and various organic compounds depending on the process used The Manufacturing Process The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product
Get PriceThe process yields concentrates containing roughly 30% copper which are sequentially fed to a smelter a furnace in which most of the some iron and sulfur are removed then to a converter or converting furnace where most of the remaining iron and other impurities are removed (Depending on the type of smelting and converting furnace used as much as 99+% of the sulfur can be recovered
Get PriceWhat we find instead is iron ore which is iron (Fe) in one of two oxidized forms Fe2O3 (hematite) or Fe3O4 (magnetite) In order to refine these into anything useable they need to be reduced normally by adding carbon at high temperature By getting the carbon C to react with the oxygen O in the ore
Get PriceStudents will learn about the mining process including its transportation by water The focus will be on an iron ore mine called Empire in Ishpeming Michigan The students will learn the cycle of iron ore going from the ground to arriving at a steel mill including all the steps in between appropriate for the fourth grade level Objectives
Get PriceThe Emergence of Iron Smelting and Blacksmithing 900 B C to the Early Roman Empire The technology required to separate iron from its ores and convert it into durable and useful objects is far more complicated than that needed to work successfully with copper and bronze
Get PriceMar 09 2007Iron is one of the most frequent metals in the terrestrial crust At the beginning it was achieved by heating the ore placed alternatively with charcoal But the temperatures achieved during those times were not enough to melt the iron and it resulted only a spongy mass which had to be cleaned of dross and hammered
Get PriceFeb 17 2016Titanium Extraction and Refining Titanium is a comparatively common element and it is the fourth most abundant structural metal on earth (just behind aluminum iron and magnesium) Workable deposits are found all over the planet and yet it remains more expensive than any of
