Herman Boerhaave (1668—1738) said in his New Method of Chemistry that Iron mines are common in most countries of Europe Norway, Poland, Germany, France, England, c. abound with them only America, which is so plentiful in gold and silver mines, has none of iron and accordingly, the natives prefer a metal of so much use infinitely beyond their own treasures (185). Although the Indians, as Boerhaave stated, did not know how to reduce iron ores, the New England colonists worked the bog iron ore of the Saugus River near Lynn, Massachusetts, as early as 1643 (186). 

Bog Iron Ores. Bog ores occur in many swampy areas particularly in glaciated areas in Europe. Asia, and North America. They occur commonly as dark-brown, cellular masses, or granular or line particles of limonite. Once important when iron furnaces were local and small, they have ceased to be of commercial importance. 

With drastic Eh increase is associated formation of bog iron ore and aggregations of native sulphur (Figure 3.35). The native sulphur accumulates in discharge surface locations of deep water with high IT S content. In mixing of this water with ground water containing O, with active bacterial participation forms insoluble in water native sulphur, which precipitates and accumulates in rock.

Terms that have been used synonymously include hematite, brown hematite, bog iron ore, pea iron ore (a variety having a pisolitic structure) and yellow ochre (q.v.). Turgite is a historical term probably describing hematite-rich limonite, therefore more likely to produce a red ochre (qq.v.) than a yellow one. 

Zinc oxide has been used to remove sitUur compounds from hydrocarbons since the 1930s, when the steam reforming process was first introduced. When a zinc oxide composition is specially prepared to have a high surface area and high degree of porosity, it can absorb more than 20 wt% sulfur in a single bed. It was the preferred choice in the early days, because the partial pressirre of hydrogen sulfide at equilibriitm imder reaction conditions, particularly in the presence of water vapour, is very small compared to that of the bog iron ore used previously to purify water gas/producer gas.
