Extracting Lead Materials from Ore. Lead is a dense, soft, lowmelting metal. Lead is the densest common metal except for gold, and this quality makes it effective in sound barriers and as a shield against resists corrosion by water, so it makes a longlasting roofing material.. Only about half of the lead materials used today are produced from mining, the rest is obtained from ...
Abstract. Using results obtained on amorphous iron oxides by extraction with Tamm's reagent as a standard reference, the M NH 2 OH· M HCl combined solution, modified to extract at 50°C for 30 min, was chosen as the most desirable extractant for amorphous iron oxides based on .

There's a lot of iron in your cereal, so much that it's possible to isolate and remove it using a little known trick. In the video below, Mr. G of Do Try This at Home will show you his secret to removing the iron content of your daily cereal, using a magnet to show exactly how much of the mineral is in a bowl of bran flakes. It's a little bit awkward, so brace yourself!

Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_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.
