  • What is the density of iron ore? Answers

    18/10/2010· The solid density of iron ore generally lies between 335 and 56 tonnes per cubic metre, depending on the particular characteristics of the ore being considered When the ore is broken up, airThe average bulk density for float ore can be taken as 251 In the case of Iron ore the average works out to be 288(PDF) Estimation of Bulk Density, Recovery Tests and01/01/2015· The average bulk density for float ore can be taken as 251The recovery percentage for the 3nos of iron ore samples varied from 5850%, 63% and 61%, the average being the float ore recovery which is around 43% Hematite (45%) is the abundant mineral Martite and goethite occupied about 10% in the ore mineral Ore mineral and gangue ratio is at 55:45 References 1 Senthil, K, 2006, Beneficiation of Low Grade Iron Ores,Estimation of Bulk Density, Recovery Tests and

  • The Density of Common Rocks and Minerals ThoughtCo

    11/05/2004· Rock density is very sensitive to the minerals that compose a particular rock type Sedimentary rocks (and granite), which are rich in quartz and feldspar, tend to be less dense than volcanic rocks And if you know your igneous petrology, you will see that the more mafic (rich in magnesium and iron) a rock is, the greater its densityrock factor (that depends on rock density, rock strength and jointing) A = ++006 RMD RDI HF( ) (36) The rock characterization factor A is calculated to correct the mean fragment size It is made up of 3 factors which are the rock mass description (RMD), rock density influence (RDI) and the hardness factor (HF) [2] 239 Determination of the Blasting EfficiencyInfluence of Blasting Parameters and Density of Rocks on19/06/2015· Phosphate rock: 274: 27: 274: 271: Potash ore: 24: 24: 240: Pyrite ore: 406: 406: 406: Pyrrhotite ore: 404: 404: Quartz: 265: 265: 265: Quartzite: 268: 268: 268: Rutile ore: 28: 28: 280: Sand, Silica: Sand stone: Shale: 263: 263: Silica sand: 267: 267: 267: Silicon carbide: 275: 275: 275: Silica rock: Silver ore: 27: Slag: 283: 274: 285: Slag iron blast furnace: 239: Slate: 257:List Table of Specific Gravity of Minerals
