    2. The reaction of acid and limestone creates an insoluble calcium salt which coats the chips making them useless. 3. The higher the percentage of Calcium Carbonate content in the limestone chips the more calcium salt is produced thus coating the chips. Some claim this percentage is an advantage but it is clearly NOT. 4.

  • Blast Furnace - ScienceAid

    Blasts furnaces are used for smelting during the production of metals such as iron, lead, zinc, and copper. A blast furnace works by blasting hot air up through the furnace while fuels, limestone, and ore move continuously through the top of the furnace. The method used in blast furnaces have been used since the 1500's.
