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 ...

When the high-grade natural iron ore was plentiful, taconite was considered a waste rock and not used. But as the supply of high-grade natural ore decreased, industry began to view taconite as a resource. Dr. E.W. Davis of the University of Minnesota, along with other scientists and engineers, conducted years of laboratory tests and experiments to find a way to take the iron ore out of the ...

Iron ore is not pure iron oxide - it also contains an assortment of rocky material that would not melt at the temperature of the furnace, and would eventually clog it up. The limestone is added to convert this into slag which melts and runs to the bottom. The heat of the furnace decomposes the limestone to give calcium oxide.

The ore is crushed, concentrated and then treated with sodium cyanide solution. This reaction forms sodium argento cyanide (Na [Ag(CN)_2]). [ Ag_S + 4NaCN rightleftharpoons 2Na [Ag(CN)_2] + Na_2S] The solution of sodium argento cyanide combines with zinc dust and forms sodium tetra cyanozicate and precipitated silver. This precipitated silver is called spongy silver. [ Zn + 2Na [ Ag .

There are two general classes of silver ore that have been mined: 1) lead-silver and 2) high-grade silver ores. Both have almost always varying amounts of gold. The lead -silver mines furnish also, as noted above, by far the greater portion of the lead produced in the United States. High grade silver ores normally have considerably less base metal content and often contain significant gold.

Origin of Iron Ore-Bodies. The ore-bodies, consisting of hematite and limonite, with sometimes a little magnetite, have been formed by two distinct processes: (a) the weathering of siderite into limonite and hematite, as at the outcrop of the original Helen Mine, Michipicoten area; (b) the leaching out of the silica, leaving the concentrated ore in place, as in the Mesabi and other Minnesota ...

It has been shown that the only method of bringing iron ore to the lake from the mines was by means of sleighs in the winter time. It became quite apparent that if any considerable business was to be done, the means of transportation would have to be improved. The average load of the sleigh was 3,000 pounds, or a little more the one and one-half gross tons, and was impossible for a team to ...

Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubies. Soft rock mining refers to excavation of softer minerals such as salt, coal ...

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ...
