The Extraction of Copper
The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( CuFeS2 C u F e S 2) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

9.3.1 Extraction of Metals
The position of the metal on the reactivity series influences the method of extraction. Those metals placed higher up on the series (above carbon) have to be extracted using electrolysis. Metals lower down on the series can be extracted by heating with carbon. The Extraction Method Depends on the Position of a Metal in the Reactivity Series.
iron and steel
Mild steel is iron containing up to about 0.25% of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things - nails, wire, car bodies, ship building, girders and bridges amongst others.

Iron sets these days.. No 3 or 4 irons?
So I have three options: 1 - buy the 4i and practice with it but not have it in the bag - just practice. That usually makes the shorter clubs much easier to hit. 2 - dump the 5i and get the next hybrid for that distance (about 190 yards) 3 - dump this 5i and get a different 5i in a more forgiving design.

Iron Production
The production of iron from its ore involves an oxidation-reduction reaction carried out in a blast furnace. Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron must be first ...

Tour Stage V300 Irons user reviews : 3.5 out of 5
Showing 1-1 of 1. [Nov 25, 2013] Anon. Shoots in the 80s. Model Reviewed: V300. They offer high trajectory, and have a nice, soft buttery feel to solidly stricken shots. However, going down to the lower irons, the 9 iron, PW, AW, SW, they are all extremely hard to get the ball airborne and make it challenging to hit the sweet spot.
