2015 4 3 Over 300 minerals contain iron but five minerals are the primary sources of iron ore. They are i magnetite Fe3O4, ii hematite Fe2O3, iii goethite Fe2O3.H2O, iv siderite FeCO3, and v pyrite FeS2 . The first three are of major importance because of their occurrence in large economically minable deposits.

2017 7 26 Stripping ratio is expressed broadly as the ratio of waste to ore. It's simply calculating how much waste has to be removed to expose how much of ore to be mined. Stripping ratio determines where the pit limit will be. There are basically three 3 forms of stripping ratios. The overall stripping ratio average stripping ratio, the maximum
2022 7 2 In surface mining, stripping ratio or strip ratio refers to the amount of waste or overburden that must be removed to release a given ore quantity. It is a number or ratio that express how much waste is mined per unit of ore. The units of a stripping ratio can vary between mine types. For example, in coal mining the stripping ratio is commonly referred to as

2022 7 2 The units of a stripping ratio can vary between mine types. For example, in coal mining the stripping ratio is commonly referred to as volume/weight. Whereas in metal mining,
2016 4 4 Determine the Stripping Ratio of the ore section green zone shown below: We know; SR = Waste/Ore, therefore; SR = 2500/5000 = 1:2 i.e. 0.5 i.e. one unit of waste is removed to recover 2 units of ore Note: We proceed by determining the area of waste materials by calculating the respective areas of the representing triangles on the section
2016 4 4 Hence the maximum allowable stripping ratio at pit limit is given as: SR Overall = Volume of Waste/Volume of Ore For Example: Determine the Stripping Ratio of the ore
