Since 1949, the Chinese government has been responsible for planning and managing the national economy. But it was only in 1978 when Deng Xiaoping introduced capitalist market principles that the Chinese economy began to show massive growth, averaging 10 percent GDP growth over the last 30 years. During that period the size of the Chinese economy has also grown by roughly 48 times, from
Molybdenum is a chemical element with symbol Mo and atomic number 42. The name is from Neo Latin molybdaenum, from Ancient Greek molybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of other metals) in
Iron processing The metal Most blast furnaces are linked to a basic oxygen steel plant, for which the hot metal typically contains 4 to 4.5 percent carbon, 0.6 to 0.8 percent silicon, 0.03 percent sulfur, 0.7 to 0.8 percent manganese, and 0.15 percent phosphorus. Tapping temperatures are in the range 1,400 to 1,500 C (2,550 to 2,700 F); to save energy, the hot metal is transferred
Where does ybdenuM CoMe froM? Molybdenum, often called moly, is an element.Molybdenum and sulfur combine to make the mineral Molybdenite. Molybdenite is found in igneous rock, which is formed deep under the crust of the Earth
Australia is the largest producer of bauxite, followed by China. In 2017, China was the top producer of aluminium with almost half of the world's production, followed by Russia, Canada, and India. Although aluminium demand is rapidly increasing, known reserves of its bauxite ore are sufficient to meet the worldwide demands for aluminium for many centuries.
Definition The term ore is defined in the current study to describe a concentration of non metallic, e.g., feldspar, or metallic minerals, e.g. spodumene, in pegmatitic rocks irrespective of its structure and position in the deposit which was or is currently mined for a profit.
High quality ores (of 60 percent iron), however, have been exhausted or have become expensive to mine. The Kursk Magnetic Anomaly, located in southwestern Russia, has iron rich quartzites.

Rhodochrosite is a manganese mineral related to the ubiquitous mineral calcium carbonate, or, calcite (common limestone is made up primarily of calcite).The calcite group of minerals includes pure calcite, dolomite, magnesite, siderite, and smithsonite, and several others. They are all carbonates with metal ions of calcium, magnesium, iron, or zinc.
Titanium is known as a transition metal on the periodic table of elements denoted by the symbol Ti. It is a lightweight, silver gray material with an atomic number of 22 and an atomic weight of 47.90.
