Extraction of Iron. Iron is extracted from its ore in the blast furnace. The main iron ore is called haematite. Haematite is iron(III) oxide Fe2O3. The iron ore contains impurities, mainly silica (silicon dioxide). in the blast furnace. The calcium silicate (called slag) floats on the liquid iron.
By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfurbearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
Iron is produced from iron carrying higher quantity of hematite or magnetite are called natural ore and can be directly fed into blast furnace for the extraction of iron ore mining process, rocks carrying high quantity of ore are identified, followed by drilling blast holes in the rocks.
May 10, 2006· Here we just talk about iron ore process simply. If you want to learn more, you can refer to URLS below. Working flow of iron ore processing Before we talk about designing of iron ore processing plant, we need learn the working flow of iron ore processing first. Raw iron ore will be sent to primary crushing equipment first.
Iron ore is converted into various types of iron through several processes. tools than any other known metal, its production was a closely guarded secret. the region from which the iron ore was taken and the method used to extract the iron.

Apr 09, 2015· Exploitation of existing iron ore deposit is the easier part of the mining operations. The harder part is to find new ore deposits and to define their extent and the iron content (grade). Exploration is the process by which the accumulations of iron ore minerals can be found in the earth's crust.
The most common ore of iron is called haematite (iron(iii) oxide). Its formula is Fe 2 O 3. Haematite is added to the top of the furnace along with coke ( carbon) and limestone. Three reactions take place during this extraction. Firstly, the carbon in the blast furnace burns with the hot air .
Uses of Iron Ore products We use iron to build bridges, buildings, cars, aircraft's, railroad, trains and home appliances like refrigerator, washing machines and utensils. Impacts on Land Landscape altered, land caves in, soil erosion Changes in land use pattern Land becomes
Iron ore occurs naturally in a variety of forms, from sandlike iron fines to solid rock masses. Crude ore, or ore mined in the natural state, seldom occurs in a pure state and requires some form of beneficiation.
and the cost of actually extracting the iron from its finite ore resource – chemicals needed (coke, limestone), constructing and running a blast furnace So, scrap .
Properties of Metals and Extraction of Metals. The least reactive metals such as gold, silver and platinum were found natural. Moderately reactive metals such as Copper Iron and Tin have been extracted using carbon based smelting. Very Reactive metals such as Potassium Sodium and Calcium have been extracted using a process known as electrolysis.

The copper ore has to be dug from the ground. The ore contains some copper mineral and lot of waste rock. The copper mine in picture 4 produces 6 tonnes of copper from every 1000 tonnes of ore. Extraction. An ore has to be changed chemically into the metal. This process is called reduction.
Open Hearth Process. Open hearth process is the modern process for the manufacture of the high grade steel. The impurities present in the cast iron are mainly oxidised by the addition of haematite ores and the rest are oxidised by O 2 of air. The percentage of C, Si is lowered down by the addition of scrap Fe.
Iron ore. Extraction of Zinc Zinc is extracted through carbon reduction of the ore Zinc blende (ZnS) ore by specially designed blast furnaces. The process contains the following steps. 1. Concentration of the ore by froth floatation method The ore is kept in a large tank containing water and pine oil.
