Iron ore mining can be broadly divided into two categories namely 1 manual mining which is employed in small mines and 2 mechanized mining is suitable for large iron ore mines Manual mining method is normally limited to float ores and small mines Mining of reef ore
Get Price· Thus iron ores are often mixed to give a desired iron phosphorus silica manganese content The copper bearing sulfide ores of Ducktown Tenn chiefly valuable for their sulfur are roasted for the manufacture of sulfuric acid it is necessary to grade the ore from different stopes carefully on the basis of sulfur content to form the right mix for this purpose

Get PriceObjective The aim of the study was to identify all the possible hazards at different workplaces of an iron ore pelletizing industry to conduct an occupational health risk assessment to calculate the risk rating based on the risk matrix and to compare the risk rating before and after the control measures
Get Price· In this method ore is mined in horizontal slices starting from the bottom to the top of the stope The broken ore is left in the mined out stope and serves as a support to the stope walls and a working platform for mining the ore above Shrinkage stoping has a high recovery but requires steep and narrow ore bodies
Get Price· Iron ore is obtained in the conventional method of open cast or underground mining and conveying the ore to the surface preparation are where it is crushed washed and transported to the smelter Here the ore is put into a blast furnace along with limestone and coke and subjected to hot air blasting and heat which converts the ore to molten iron

Get Price· Metal is an element compound or alloy that has an abundance of different physical chemical electrical and mechanical properties It can often be difficult to identify a metal s type from mere sight alone Here is a guide to some of the most common metal types and how you can identify them more easily and accurately
Get Price· Contact ores Iron ore deposits formed at or near the contact between igneous rocks and sedimentary rocks are normally composed of magnetite and hematite with associated carbonates and pyrite The ore deposits are usually in the sedimentary rocks as irregular or tabular replacement bodies
Get PriceThe committee responsible for this document is ISO/TC 102 Iron ore and direct reduced iron Subcommittee SC 3 Physical testing This third edition cancels and replaces the second edition ISO 8371 2007 which has been technically revised to address the care needed during hand sieving to introduce the mechanical sieving and to exclude the reference to ISO 4701
Get PriceAs the part of the project work hazard identification and risk analysis was carried out for an iron ore mine and a coal mine and the hazards were identified and risk analysis was carried out The different activities were divided in to high medium and low depending upon their consequences and likelihood
Get Price· In the LDA method MgO Fe SiO 2 and P are the feature components contributing the most to the identification of 16 brands of iron ore Based on the findings the multi components are distinct variables to establish an internationally recognized model of iron ore brand identification
