Lead

Lead is a very corrosion-resistant, dense, ductile, and malleable blue-gray metal that has been used for at least 5,000 years. Early uses of Lead included building materials, pigments for glazing ceramics, and pipes for transporting water. The castles and cathedrals of Europe contain considerable quantities ofLead in decorative fixtures, roofs, pipes, and windows. Prior to the early 1900s, uses of Lead in the United States were primarily for ammunition, brass, burial vault liners, ceramic glazes, Leaded glass and crystal, paints or other protective coatings, pewter, and water lines and pipes. With the growth in production of public and private motorized vehicles and the associated use of starting-lighting-ignition (SLI) Lead-acid storage batteries and terne metal for gas tanks after World War I, demand for Lead increased. Most of these uses for Lead continued to increase with the growth in population and the national economy. Contributing to the increase in demand for Lead was the use of Lead as radiation shielding in medical analysis and video display equipment and as an additive in gasoline. In Iran, Lead has known since 3rd millennium before Christ. Nowadays Iran has many large mines of Lead such as Angooran, Nakhlak, etc. So Iran is one of the biggest Lead Suppliers in Middle East. Marjan Mineral Company has a great trading communication with most of Lead mines, and can provide all necessary things for exporting their products. Read more . . .

Different types of Lead Ores

The abundance of Lead in the Earth's crust is estimated to be between 13 and 20 parts per million. It ranks in the upper third among the elements in terms of its abundance. The more important Lead minerals are:

• Galena (PbS, 86% Pb)
• Anglesite (PbSO4, 68% Pb)
• Cerussite (PbCO3, 77% Pb)

Lead Usages:

Prior to the early 1900s, Lead was used in the United States primarily in ammunition, burial vault liners, ceramic glazes, Leaded glass and crystal, paints or other protective coatings, pewter, and water lines and pipes. Following World War I, the demand for Lead increased because of growth in the production of motorized vehicles, many of which use Lead-acid batteries to start their engines. The use of Lead as radiation shielding in medical analysis and video display equipment and as an additive in gasoline also contributed to an increase in the demand for Lead. Read more . . .

Molybdenum

Molybdenum is a chemical element with symbol Mo. Molybdenum does not occur naturally as a free metal on Earth, but rather in various oxidation states in minerals. Molybdenum is one of the Copper paragenesis. The most important application of Molybdenum is in steel alloys. Alloys that are made by Molybdenum have strategic uses in aviation industries. Cathodic Copper production of Iran exceeds 200000 ton in year. So Iran has a great potential to produce Molybdenum as byproduct of Copper. Major raw materials for production of Molybdenum are separated from Copper with leaching. According to the published statistics by United States Geological Survey (USGS), Iran has 2.33 percent of Molybdenum production in 2012. So Iran is one of the best Molybdenum Supplier in the world. Marjan Mineral Company honorably can provide suitable conditions for Molybdenum Exporting. Read more . . .

Molybdenum Usages:

• Molybdenum has a very high melting point so it is produced and sold as a grey powder. Many Molybdenum items are formed by compressing the powder at a very high pressure.
• Most Molybdenum is used to make alloys. It is used in steel alloys to increase strength, hardness, electrical conductivity and resistance to corrosion and wear. These ‘moly steel’ alloys are used in parts of engines. Other alloys are used in heating elements, drills and saw blades. Read more . . .

Copper Ore

What is Copper Ore?

Copper is a chemical element with symbol Cu. It is a ductile metal with very high thermal and electrical conductivity. Pure Copper is soft and malleable; a freshly exposed surface has a reddish-orange color. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys. Its compounds are commonly encountered as Copper salts, which often impart blue or green colors to minerals such as azurite and have been widely used historically as pigments. Architectural structures built with Copper corrode to give green verdigris (or patina). Decorative art prominently featuresCopper, both by itself and as part of pigments. These are the most common Copper Ores in nature:

• Chalcopyrite (CuFeS2, 34.5% Cu)
• Chalcocite (Cu2S, 79.8% Cu)
• Covellite (CuS, 66.5% Cu)
• Bornite (2Cu2S•CuS•FeS, 63.3% Cu)
• Malachite (CuCO3•Cu(OH)2, 57.3% Cu)
• Azurite (2CuCO3•Cu(OH)2, 55.1% Cu)
• Cuprite (Cu2O, 88.8% Cu)

Among mentioned items, Chalcopyrite and Chalcocite are very important. The largest source of Copper is from porphyry ore deposits in which one or a combination of the aforementioned minerals occurs. A typical Copper sulphide ore contains various levels of iron sulphide types that generally include pyrite (FeS2) and Chalcopyrite. Often gold and silver are present which may either be associated with the sulphides or are free. The gangue particles can consist of a range of silicate minerals from quartz to Talc and clays. Carbonate mineral gangue can also be present. Read more . . .

Copper Ore Usages:Copper is extracted from Copper ore in Copper processing factories. The usage of Copper can be significantly categorized as below:

• In Communication Sector: Copper products are being used for both long and short-range cables, wires, pipes and links. Copperis also widely used in making of PCB (Printed Circuit Board) for computers and electronic equipments.
• In Electricity & Energy Sector: Copper is a best conductor of electricity and heat. It can be easily transformed to alloy i.e. combined with another metal to make new alloys like bronze and brass. These alloys are stronger, harder, and resistant to corrosion as compared to pure Copper.
• In Plumbing and Heating: Copper tubes are the standard plumbing material for potable water and heating systems. It is a preferred material of professional plumbers and heating engineers. Read more . . .

Iron Ore

Iron is very important and strategic commodity and has an undeniable role in genesis, growth and development of modern advanced civilization. Indeed maybe there is no other material which can be compared with influence of Iron in mankind life. Abundance of Iron and its special characteristics marginalized the other minerals so soon. According to the available evidences, Iron was extracted in middle of second millennium B.C. by Far East people for first time. Usage of Iron widely extended in neighbors specially Iran so quickly. The oldest objects was found in Iran belong to Iron era (about 1200-1450 years B.C.), but due to few quantity, It seems, they were imported from other places by the spoils of war. After 1200 years B.C. Iron was produced in Iran widely and many different tools were made by Iron. According to the above mentioned, Iron Ore mining in Iran has a big history. Today Iran is one of the best exporters of Iron Ores in Middle East and has lots of large Iron mines such as Choghart, Chador Malu, Sangan, Bafgh and etc. It's Marjan Mineral Company's honor to have a great trading communication with many of Iron mines in Iran. Marjan Mineral Company can do all necessary actions for Iron Ore exporting. Read more . . .

Iron Ores are rocks and minerals which economically contain metallic Iron. Iron oxides are the major component of Iron Ores. They have various colors from dark grey, bright yellow, deep purple, to rusty red. These are common Iron minerals:

• Magnetite (Fe3O4, 72.4% Fe)
• Hematite (Fe2O3, 69.9% Fe)
• Goethite (FeO(OH), 62.9% Fe)
• Limonite (FeO(OH).n(H2O))
• Siderite (FeCO3, 48.2% Fe)

Hematite and Magnetite are the most abundant and economic minerals of Iron. Iron Ore is the raw material used to make pig Iron, which is one of the main raw materials to make steel. Most of the mined Iron Ore is used in steel industry. Perhaps only Oil and Gold has more importance than Iron in global economy.

Iron Ore Usages:

Iron ore is usually smelted to produce pig Iron (metallic Iron), which is used to make steel. It is for this reason Iron is perhaps one of the most important metals used in developed and developing economies. There is also wrought Iron (low in carbon) and cast Iron (otherwise known as pig Iron), and corrugated Iron structural sheeting, a recognizable material in the buildings throughout the Australian outback. The pure Iron metal is strongly magnetic, melts at 1528°C. Magnetite ore is used to remove impurities in coal washing, and its magnetic qualities enable recovery and reuse. Read more . . .
