Industries can also look to recycle waste water. For example, when using water for cooling in steel-making, the water can be recycled again and again in the process. In agriculture, drip-feed irrigation systems could be used rather than sprinkler systems. 15.
Since they are very hot they are used in a heat exchange process to heat incoming air, therefore making the process more economical. Conversion of Iron into Steel Iron produced using the blast furnace method is called pig iron.
Steel-making: the basic oxygen process Impurities in the iron from the Blast Furnace include carbon, sulfur, phosphorus and silicon. These have to be removed. Removal of sulfur: Sulfur has to be removed first in a separate process. Magnesium powder is blown

To make it more useful, most iron is made into steel. STEEL MAKING Process In the Basic Oxygen Process, excess carbon is burnt off in a converter and the correct amount of carbon added to make steel. Other metals (e.g. chromium) can be added to 2 3
It is found as the element in sulphur beds 200m below the ground in volcanic areas and also in metal ores such as copper pyrites (iron sulphides) and zinc blende and also in volcanic areas. Superheated water at 170 C and hot compressed air are pumped into layers of sulphur through pipes.

Process in which sulfur and sulfide ores are turned to sulfur dioxide then to sulfur trioxide then to oleum and then to sulfuric acid Step 1: Making sulfur dioxide from burning sulfur or sulfide ores S(s) + O₂ → SO₂(g) 4FeS² (s)+ 11O₂ → 2Fe₂O₃(s) + 8SO₂(g) Step 2
Low grade ores are usually uneconomic to mine and process, but high grade ores have a high enough metal content to be worth mining and extracting the metal. The metal ore, a mineral or mixture of minerals from which economically viable amounts of metal can be extracted , i.e. its got to have enough of the metal, or one of its compounds, in it to be worth digging out!
1 Two of the main uses of zinc are for galvanising and for making alloys. One of the main ores of zinc is zinc blende, ZnS. There are two stages in the extraction of zinc from this ore. (a) Stage 1 Zinc oxide is made from zinc blende.Describe how this is done and
Textiles, steel making, shipbuilding are examples. Low wages, access to raw materials, proximity to new large markets and reduced costs of shipping have all led to these changes. Developed economies have replaced the manufacturing sector with a service based economy and high-tech manufacturing.
About 67% of the global crude steel total output is through the Basic Oxygen Furnace Steelmaking process and is recognized as the dominant steelmaking technology. In U.S alone the usage figure is 54% and slowly declining due primarily to the advent of …
