Toxic metals, including "heavy metals," are individual metals and metal compounds that negatively affect people's health. Some toxic, semi-metallic elements, including arsenic and selenium, are discussed in this page. In very small amounts, many of these metals are necessary to support life. However, in larger amounts, they become toxic.

Bricks of 100 percent chromium ore have been largely replaced by bricks composed of mixtures of chromite and added magnesia for greater refractoriness, volume stability, and resistance to spalling. One of the refractories used in the fused-cast condition is composed of …
source for the metallic element chromium, which is used in the metallurgical, chemical, and refractory industries. Podiform chromite deposits are small magmatic chromite bodies formed in the ultramafic section of an ophiolite complex in the oceanic crust. These deposits have been found in …
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.

Chromite is a mineral that contains chromium. It is considered a strategic mineral, which generally means that it is necessary for military and industrial use during periods of national emergency. The strategic mineral concept was created during World War I and became law just prior to World War II with the passage of the Strategic Minerals Act ...
Much of the Gold that's mined comes from Gold ores rather than Gold specimens. Gold ore is often brown in color and contains a very little trace of Gold. To extract the Gold, Gold ores are crushed, and then the Gold is separated from the ores using different methods. Gold nuggets are a popular form of Gold, especially with Gold collectors.
Chromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 °C (3,375 °F) and boils at 2,672 °C (4,842 °F). In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated
Apr 11, 2006· Gold is the sun metal. It has therefore been linked over the millennia with everything to do with health, wealth, and growth. On another level, it is about slow flow towards accomplishment. When working with gold, bear in mind that most things sold as gold these days are alloys. 24k gold is pure gold …
Chromium steel, which resists warping or melting under conditions of extreme heat, is ideal for high-temperature applications such as jet-engine components. The principle chromium ore, chromite, is heat resistant in the same way. It is this property, along with its chemical stability, that makes chromium useful as a refractory material.

The ore minerals in most of the world's iron and manganese reserves were chemically precipitated in the ocean and accumulated on the sea floor. Placer deposits are heavy metallic minerals, such as iron or titanium minerals, or native gold or diamonds, that have been concentrated by wave or water action in a river or beach environment. The ...
Chromium (Cr) has a wide range of uses in metals, chemicals, and refractories. It is one of the Nation's most important strategic and critical materials.
