    • ‘Water from some sites contained manganese, often a component of the mineral-rich water discharged from vents.’
    • ‘And it provided vital information on lime requirement, phosphorus, potash, magnesium, copper, manganese and zinc.’
    • ‘Uptake of aluminum, iron and manganese has not been as extensively studied in algae.’
    • ‘The oxygens which were originally attached to the manganese are still attached in the neutral complex.’
    • ‘Carbon-manganese steels are in general use for the rails; too much carbon makes the steel brittle, too much manganese makes it hard to weld.’

    • ‘These changes were associated with large increases in phosphorus, potassium, zinc, iron, manganese, and copper.’
    • ‘Cobalt, nickel and manganese are metals with iron-like properties.’
    • ‘Groundwater also contains salts of calcium, magnesium, iron, and manganese.’
    • ‘These alloys usually contain manganese as an impurity because wrought metal scrap is used in preparing them.’
    • ‘Less abundant elements, which are equally necessary for life, include calcium, manganese, iron, and iodine.’
    • ‘Nitrates and trace metals, such as iron, manganese, copper, and zinc, should be kept to a minimum.’
    • ‘The list includes sodium, potassium, calcium, magnesium, manganese, iron, cobalt, copper, zinc, and molybdenum.’
