Calamine the World Health Organization's List of Essential Medicines for being one of the most effective and safe medicines needed in a health system. Calamine is available over the counter as a generic medication. The wholesale cost in the developing world is about US$0.25–3.85 per 100-ml bottle. In the United Kingdom, it costs the National Health Service about £0.44. Calamine is used to treat itchiness. This includes from sunburn, insect bite, or other mild skin conditions. Calamine is mixed with either zinc oxide (ZnO) with about 0.5% ferric oxide (FeO) or a zinc carbonate compound. Calamine lotion is a component of
Iron ore by Fe oxidation on the anodic zone inside the pit must be quickly compensated / neutralised by negative charges brought by the electrokinetic migration of anions in the capillary pit. Some of the electrochemical processes occurring in a capillary pit are the same than these encountered in capillary electrophoresis. Higher the anion electrokinetic migration rate, higher the rate of pitting corrosion. Electrokinetic transport of ions inside the pit can be the rate limiting step in the pit growth rate. Iron ore Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich
