  • Ways to Separate Metal From Ore Sciencing

    Small, gas powered smelting furnaces can also be used to separate metal from ore. A cylindrical sheet metal container is built over a gas flame (propane can also be used). Then, a network of tubing is fitted around the smelter. The tubing includes a gas line, an air line, and other piping. A crucible (usually made out of graphite or clay) is used to dip into the smelter to extract molten metal and ore.

  • Types of Extraction S cool, the revision website

    An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to extract from its compound.
