Eventually, another ore will respawn and the rock will regain its vein of colour. Players can only mine a rock when ore is available. Ore respawn times differ with the level requirement of the rock and the amount of people on the server (e.g., runite rocks can take up to 25 minutes to respawn, while iron rocks take about 10 seconds).

Naturally-occuring iron ore varies in it's content. Also, you haven't said whether it is "benefacted ore" (crushed, with gangue material removed), or straight out of the ground. Obviously, if the latter is the case, even very rich ores seldom cont...
Mining companies use this reaction to obtain iron from iron ore: Fe2O3(s)+3CO(g) → 2Fe(s)+3CO2(g) The reaction of 177 g of Fe2O3 with 82.8 g of CO produces 72.7 g of Fe. Calculate the theoretical yield of solid iron. ANSWER: 110. g Fe
Extensive development of low grade ores and open pit mining began after World War 11, and a relatively new process, agglomeration, then began to yield an iron ore concentrate that contained about sixty-five per cent iron compared with fifty-six to sixty per cent from the average underground workings of the high grade ore.
Question: The Following Reaction Is Used To Obtain Iron From Iron Ore: Fe2O3(s)+3CO(g) ? 2Fe(s)+3CO2(g) The Reaction Of 172 G Of Fe2O3 With 84.2 G Of CO Produces 71.8 G Of Fe. Calculate The Theoretical Yield Of Solid Iron. Express The Mass In Grams To Three Significant Figures.

The only source of primary iron is iron ore. The USGS defines iron ore as 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 (Fe3O4) and hematite (Fe2O3). It's .
For a magnetic separation of iron ore beneficiation process factory, the known ore grade α =35. 86%Fe, the concentrate grade β=60-89% Fe, tailings grade V =8. 76% Fe, the yield of iron concentrate γk:
Aug 20, 2008· An iron ore samp;le contains Fe2O3 plus other impurities. A 752-g sample of impure iron ore is heated with excess carbon, producing 453 g of pure iron by the following reaction: Fe2O3 (s) + 3C(s) ---->2Fe (s) + 3CO(g). what is the mass percent of Fe2O3 in the impure iron ore sample? Assume Fe2O3 is the only source of iron and that the reaction is efficient.
This is a comprehensive list of ore veins, their requisite skill levels, the items they contain, and their approximate geographic locations. It is by no means completely comprehensive, so keep that in mind. In additon to their mining skill requirements, all Northrend mining nodes require level 65 to mine.
With an ore body 4km long, 80m thick and reaching a depth of 2km, LKAB's Kiruna is the world's largest, most modern underground iron ore mine. Since mining began at the site over 100 years ago, Luossavaara-Kiirunavaara AB (LKAB) has produced over 950Mt of ore, yet only one third of the original ore body has been extracted.
High-quality ores (of 60 percent iron), however, have been exhausted or have become expensive to mine. The Kursk Magnetic Anomaly, located in southwestern Russia, has iron-rich quartzites. Sweden is another producer of iron ore, notably in the Kiruna region. Deposits in .

Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron-ore mining methods vary by the type of ore being mined.
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 industries.
