Minnesota is the largest producer of iron ore and taconite in the United States. Even though nearly all of the high grade natural iron ore in Minnesota has already been mined, advances in technology have found a use for lower grade iron ore, called taconite.
Taconite is a low-grade iron ore. 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.
Most metals that we use come from metal ores found in the earth's crust. Metal ores are made up of different compounds. Bauxite for example contains about 99 percent aluminum and magnetite about 72 percent iron. These metal ore deposits that contain large percentages of a single element are the ...
Any use you can think of for a metal - whether it be in a cell phone battery, an automobile part, or even a medicinal ingredient - is thus, also a use for an ore.
The term ore is used to refer to a rock that contains minerals such as metals. In general, ores are oxides, sulfides, silicates or "native metals," those found in nature. Oxides and sulfides are called such because the minerals contain oxygen or sulfur, respectively, which has formed a …
Uranium compounds have been used for centuries to color glass. A 2,000 year old sample of yellow glass found near Naples, Italy contains uranium oxide. Uranium trioxide (UO 3) is an orange powder and has been used in the manufacture of Fiestaware plates. Other uranium compounds have also been used to make vaseline glass and glazes.
Preparing the ore 1 Silver ore is crushed into pieces, usually with 1-1.5 in (2.5-3.75 cm) diameters, to make the material porous. Approximately 3-5 lb (1.4-2.3 kg) of lime per ton of silver ore is added to create an alkaline environment.

Several processes can then be used to separate the gold from the ore. The most common techniques in the United States use cyanide in various ways. In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore.
Chromium: A Thoroughly Modern Metal Hidden in Plain Sight. Crocoite is unusual in appearance but rarely found. Beginning with the use of chrome plating in the art deco designs of the 1930s through its heyday in the cars, furniture and appliances of the 1950s and 1960s, chromium has been closely associated with the fast-paced modern world.
