Iron ore is any rock or mineral from which iron can economically be extracted. It comes in a variety of colors, including dark gray, bright yellow, deep purple, and rusty red. The iron comes in the form of iron oxides such as magnetite, hematite, limonite, goethite, or siderite. Economically viable forms of ore contain between 25% and 60% iron. In the old days of mining, some ores, known as "natural ores," had 66% iron and could be fed into iron-making blast furnaces directly. The three primary sources of iron ore are banded iron formations, magmatic magnetite ore deposits, and hematite ore. The most metal is extracted from banded iron formations, geological structures laid down mostly between 3 and 1.2 billion years ago. Blue-green algae released oxygen in the days when the atmosphere and oceans were very oxygen-poor, binding together with dissolved iron in the world's oceans. These iron fixation events went through cycles as the algae had alternating blooms and busts, leaving the characteristic bands seen in banded iron formations. This ore is in either the form of magnetite or hematite. Banded iron formations are found on all continents, but especially rich deposits are found in Australia, Brazil, and the United States. Another prominent source of iron is found as magmatic magnetite iron ore deposits, formed during ancient volcanic eruptions that released large amounts of magnetite which later crystallized. Granite-associated deposits have been found in places like Malaysia and Indonesia and require very little post-processing to extract the iron. Titanomagnetite, a special class of magmatic magnetite ore, also serves as a source of titanium and vanadium, which is extracted via specialized smelters. A third source is in hematite ore deposits, which are found on all continents, but especially in Australia, Brazil, and Asia. Most hematite originates from banded iron formations that have undergone chemical alteration over billions of years due to hydrothermal fluids. The world's largest producer of iron ore, Vale, located in Brazil, produces it from hematite ore. Vale produces 15% of the entire world's iron supply. In total, worldwide ore production is about one billion metric tons.
Manganese is a chemical element, designated by the symbol Mn. It has the atomic number 25. It is found as a free element in nature (often in combination with iron), and in many minerals. Manganese is a metal with important industrial metal alloy uses, particularly in stainless steels. Historically, manganese is named for various black minerals (such as pyrolusite) from the same region of Magnesia in Greece which gave names to similar-sounding magnesium, Mg, and magnetite, an ore of the element iron, Fe. By the mid-18th century, Swedish chemist Carl Wilhelm Scheelehad used pyrolusite to produce chlorine. Scheele and others were aware that pyrolusite (now known to be manganese dioxide) contained a new element, but they were not able to isolate it. Johan Gottlieb Gahn was the first to isolate an impure sample of manganese metal in 1774, byreducing the dioxide with carbon. Manganese phosphating is used as a treatment for rust and corrosion prevention on steel. Depending on their oxidation state, manganese ionshave various colors and are used industrially as pigments. The permanganates of alkali and alkaline earth metals are powerful oxidizers. Manganese dioxide is used as the cathode (electron acceptor) material in zinc-carbon and alkaline batteries. In biology, manganese(II) ions function as cofactors for a large variety of enzymes with many functions.[1] Manganese enzymes are particularly essential in detoxification of superoxide free radicals in organisms that must deal with elemental oxygen. Manganese also functions in the oxygen-evolving complex of photosynthetic plants. The element is a required trace mineral for all known living organisms. In larger amounts, and apparently with far greater activity by inhalation, it can cause a poisoning syndrome in mammals, with neurological damage which is sometimes irreversible.
Chrome Ore The only ore of chromium, the metal used to make stainless steel, nichrome and chrome plating. What is Chrome Ore? Chrome Ore is an oxide mineral composed of chromium, iron and oxygen (FeCr2O4). It is a dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when Chrome Ore-bearing rocks are altered by heat or weathering. Chrome Ore is important because it is the only economic ore ofchromium, an essential element for a wide variety of metal, chemical and manufactured products. Many other minerals contain chromium, but none of them are found in deposits that can be economically mined to produce chromium. Properties of Chrome Ore Chrome Ore can be challenging to identify. Several properties must be considered to differentiate it from other metallic ores. Hand specimen identification of Chrome Ore requires a consideration of: color, specific gravity, luster, and a characteristic brown streak. The most important clue to identifying Chrome Ore is its association with ultrabasic igneous rocks and metamorphic rocks such as serpentinite. Physical Properties of Chrome Ore Chrome Ore is sometimes slightly magnetic. This can cause it to be confused with magnetite. Chrome Ore and ilmenite have very similar properties. Careful observations of hardness, streak and specific gravity are required to distinguish these minerals in hand specimens.

Lead powder and lead concentrate are different forms of lead that serve various industrial purposes. Here's an overview of each: Lead Powder: Form: Lead powder refers to finely ground particles of lead metal, typically in powder or granular form. Uses: Battery Manufacturing: Lead powder is often used in the production of lead-acid batteries. Radiation Shielding: Lead is known for its ability to absorb and shield against radiation, and lead powder can be used in various applications where radiation protection is required. Ammunition: Lead powder is a component in the production of ammunition and bullets. Metal Coatings: It may be used in the manufacturing of certain types of paints and coatings. Lead Concentrate: Form: Lead concentrate is a raw material derived from the mining and processing of lead ores. It is not a pure form of lead but rather a mixture containing lead and other minerals. Composition: Lead concentrate typically contains lead sulfide (galena) as the primary mineral, along with other sulfide minerals. Processing: The lead concentrate is further processed through smelting to extract pure lead metal. Uses: Lead concentrate is a crucial intermediate product in the production of refined lead. It is an essential raw material for lead smelters, where the lead is separated from impurities and processed into the desired forms. Lead concentrate may also contain valuable by-products such as silver and zinc.
Iron ore fines come from the natural raw iron ore through the process of mining, crushing and screening, where the iron ore is separated into lumps and fines. Iron ore is done in this fashion so that it can be used for the iron/steel making industry
