Iron is concentrated by the process of calcinations. Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.
Haul trucks are rigid trucks that are used in open pit mining to carry loads ranging from 50 to 450 tons. They are generally used in the larger operations mining copper, gold, iron ore, coal, or oil sands. The largest trucks cost about million. The largest tires are about 14ft in diameter, cost over 65,000 and due to the extremely tough

Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron . ore is the material from which the metal iron is produced.. The process of mining dates back to prehistoric times.. Prehistoric people first mined flint, which was ideal for tools and weapons since it breaks into shards with sharp edges.
What is Iron Ore Mining Market And Opportunities and Challenges Iron ores are the rocks and minerals from which metallic iron is extracted.

iron ore is expected to rise by more than 200 million tonne per year to meet the internal demand export. This additional requirement of iron ore will need beneficiation of low grade ore/fines to get the major portion of increased demand. This paper deals in brief to use of available methodologies for beneficiation of iron ore in Indian context.

Process Overview Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or openpit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions.
Six steps to process iron ore. 1. Screening. We recommend that you begin by screening the iron ore to separate fine particles below the crusher's CSS before the crushing stage. A static screen is used to divert the fine particles for crushing. This step prevents overloading the crusher and increases its efficiency.
