Page 14 - Association and separation of manganese and iron. — Manganese and iron are frequently found together in the same deposits, but they also occur separately. As both ores are derived from the same source, are taken up in solution together, and under many conditions are precipitated by the same influences, their frequent association in ore deposits is what would be expected. Under certain circumstances, however, iron and manganese may be precipitated separately, and hence the not uncommon occurrence...
