17% of the solid waste generated, amounting to approximately 6, 12,300 tonnes in 2008-09 was used to fill low-lying areas and for peripheral road construction around Jamshedpur. Tangshan Iron & Steel, the flagship site of Chinas largest steelmaker, Hebei Iron & Steel (HBIS) Group, the second largest producer of steel in the world

how to treat wastewater from iron and steel industry

how to treat wastewater from iron and steel industry

Leaching wastes are formed in the iron launders used to extract copper from oxide ore and to recover copper from tailings of sulphide ore, low grade ore and mine waters. Because these operations are located mainly in the arid rocky area, treatment of this waste is necessary to prevent making streams unpotable and unfit for agricultural or recreational use

lecture 4: mining waste

Waste rock is the rock that is excavated to reach the ore. The amount of waste rock that needs to be removed depends on the geometry and location of the ore body, along with the mining method used and the composition and stability of the rocks. The ratio between waste rock and ore

Mining Waste Products. The types of waste materials generated are dependant upon the type of mining activity. Around the Fal Estuary there have been effectively three main types of mining activity: (1) the recovery of cassiterite from the river sediments (so called tin streaming or placer mining); (2) the underground and opencast mining for metal (hard rock mining); and (3) opencast mining for

Jan 01, 1993 Iron ore has been mined in Europe by both underground and surface mining methods. The main types of iron ore and where they can be found in Europe are shown in Table 9.2. Mining produces waste rock and soil which may be devoid of vegetation because of its poor nutrient status. Spoil from iron ore mining in Lorraine, eastern France contains pyrite and is a source of acid mine drainage (see

Recycling of oxidized iron-bearing materials and coal and coke waste products in integrated steel plants is a problem which is coming under control. These waste products amount to about 10% by weight of the total steel output. Suitable agglomeration processes can directly recycle over 80% of this material as charge material to the iron blast
