what type of mineral is used in iron ore sometimes used in jewelry?
Depending on the type of jewelry you are referring to, it can be brass with copper and zinc, stainless steel with chromium, and silver with copper. Lead and cadmium are usually found in some cheap costume jewelry but these materials are known to cause cancer and other health issues. http://www.jgoodin.com/Home/Support/KnowledgeBase/BaseMetals.aspx

This country is a leading producer of chromium and its capital is tirane?
Tirane is the capital of Albania. Albania is a leading producer of chromium and other resources include coal, bauxite, copper and iron ore.
What is the minning method of chromium?
Chromium is mined as chromite ore. Either as minerals with iron or magnesium. Chromite can be found mostly in South Africa, while Kazakhstan, India, Russia, and Turkey are also sizeable producers. Chromite deposits are mined by both underground and surface techniques. After excavation, the minerals are smelted in a furnace. Finely divided ores do not smelt efficiently, so a number of processes are used to counteract. Fines can be blended with fluxes and coke (the principal source of carbon) and then preheated before being charged into an electric smelting furnace. After smelting the ore is refined at 2,080° C (3,775° F) temperatures with100 kilopascals pressure in a pressure chamber.
Where is the birthplace of chromium?
Chromium was discovered in a red lead ore from Siberia by Louis Nicolas Vauquelin, however, he was in Normandy, France at the time. The term birthplace is vague. Most chromium is mined in South Africa, Kazakhstan, Russia, and India. Chromium was first used in China about 2300 years ago. Chromium first attracted the attention of Europeans in 1761 in Russia's Ural Mountains. It was first isolated from these sources in 1797. Chromium sometimes comes to earth in meteorites. One difficult to locate fact is how chromium is believed to be created (i.e. in stars, supernovae, or the Big Bang, etc.)
What ore did ruby come from?
Rubies are not formed from ore like metals. They are instead a variety of the mineral corundum, which is a crystalline form of aluminum oxide. Rubies get their red color from the presence of chromium in their structure.
What is the symbol for the element chromium and what can it be used for?
The chemical symbol of chromium is Cr.For the applications of chromium see this link.
How is chromium made?
Chromium is typically obtained through the mining and extraction of chromite ore. The ore is processed to extract chromium by either using the traditional method of roasting and leaching, or modern techniques such as aluminothermic reaction or electrolysis. The extracted chromium is then further processed and refined to the desired form for use in various industries.
What is chromium used in?
Chromium is found in some chrome spray paint.
