demonstrates the historical process known as smelting and could theoretically be used to determine the empirical formula of other metal oxides found in nature. This paper explains how the process of smelting and how metals can be extracted from their ores. This is because a few metals can be found in their elemental forms in nature. It explains the process which involves the use of a chemical reaction to isolate the metal in its elemental form from an ionic compound which includes the metal as a salt

Cobalt is between iron and nickel on the periodical table and found in only . 001-.002 percent of the earth¹s crust. Cobalt was first found in the Harz Mountains. People in the silver mines dug up arsenic cobalt ores. Then‚ because they thought the ores contained copper‚ heated the ores releasing arsenic trioxides. Cobalt was named after the German kobold. A kobold was said to be an underground goblin or demon. In

The Usage of Blast Furnace What is a Blast Furnace? A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals‚ generally iron. In a blast furnace‚ fuel‚ ore‚ and flux (limestone) are continuously supplied through the top of the furnace‚ while air (sometimes with oxygen enrichment) is blown into the lower section of the furnace‚ so that the chemical reactions take place throughout the furnace as the material moves downward. In the blast furnace‚ it is so

Everyone is familiar with the three ’R’s - Reduce‚ Reuse and Recycle. But does every citizen follow it religiously? The relationship between environmentally aware citizens and a balanced ecosystem is direct. With the rising concern about global warming and climate change‚ recycling has gained a lot of importance. Here are some advantages of recycling different types of material. Plastic » According to the Stanford University PSSI Recycling Center‚ if you recycle 1 ton of plastic‚ it saves
