Qi Da Mountain Iron Ore Deposit
Qi Da Mountain Iron Ore Deposit is a typical iron ore deposit in Liaoning province, China. It has a long mining history and is one of the largest iron ore deposits in China. Located in the Saertu District of Fuxin City, Liaoning Province, the deposit has a total area of about 100 km2 and holds an estimated 2.5 billion tons of iron ore. The deposit has been mined for over a century, and has produced more than 1.7 billion tons of iron ore.
The deposit is composed of four main ore-bearing stratigraphic units. The lowermost unit is composed of quartzite and sandstone from the Middle and Upper Cambrian systems. The other three units contain three types of iron ore: high-grade hematite ore, magnetite ore and some copper-bearing iron ore. The mineral composition of the iron ore consists mainly of hematite, magnetite, and martite. These ores are distributed mainly in the metamorphic and igneous rocks of the Qinling Mountains, which form part of the northern border of Liaoning Province and were formed during the late Mesozoic era. The average mineral content of the ore is approximately 75% iron, 18.5% silica, 1.7% alumina, and 0.7% phosphorus.
The ore is mainly located in three areas: the western, middle and eastern parts of the deposit. The western part contains mainly high-grade hematite ore, and the eastern part contains mainly magnetite ore. The middle part contains a mix of the two types of ore, as well as some copper-bearing iron ore which has potential for producing steel. Northern Qi Da Mountain Iron Ore Deposit is a major magnetite ore producing area in Liaoning Province.
Qi Da Mountain Iron Ore Deposit has long been exploited for a wide variety of uses. Iron-bearing rocks from the deposit have been used for bricks, cement, and for producing cast iron. In addition, the ore has been used for the production of steel. For more than a century, the ore has been mined by open-pit and underground mining, with annual production levels varying from 1.2 to 3.3 million tons. In recent years, open-pit mining has generally been favored due to its cost-effectiveness and high production rates.
The transportation of the ore from the deposit is mainly done by rail and road. From Qi Da Mountain Iron Ore Deposit, there are multiple railway links, including the Fentu Railway and the Yantai Railway. In addition, there are multiple roads links leading to and from the deposit, the most prominent being the Jiushi Expressway.
The ore from Qi Da Mountain Iron Ore Deposit is mainly used in the production of steel. After it is extracted from the deposit, it is sent to steel plants and smelters throughout China. The steel from Qi Da Mountain Iron Ore Deposit is of high quality and is used to produce a range of products, including construction materials and automobile parts.
Qi Da Mountain Iron Ore Deposit is a significant contributor to the economy of Liaoning Province. The ore from the deposit is a key input for the steel industry, and its production and transport create jobs and generate income for the local economy. In addition, the ore is a source of valuable minerals, which can be further refined to create materials which are used in various industries. The deposit is a major contributor to the provincial economy and provides a stable source of income for the local population.
