Emerging Technologies for Iron and Steelmaking
The iron and steel industry has undergone a technological revolution in the last 40 years In a relatively short time the North American industry has observed the complete disappearance of basic open hearth processing as well as the wide spread adoption of continuous casting and the near complete shift of long product production to the electric arc furnace sector.

Pickling Steel American Galvanizers Association
Low temperature mill scale consists of two iron oxide layers and develops when steel is heated in an annealing or finishing procedure at less than 1070F Cracks in either type of scale allow the pickling acid to penetrate the scale layers and dissolve the inner layer causing the bulk of the scale to be removed in flakes.

The chemistry of iron in soils and its availability to plants
Abstract The solubility of iron in soils is controlled by Fe OH 3 soil in well‐oxidized soils by Fe3 OH s ferrosic hydroxide in moderately oxidized soils and by FeCO3 siderite in highly reduced soils The Fe III hydrolysis species Fe OH 2 and Fe OH 3 are the major solution species of inorganic Fe but they are maintained too low to supply available iron to plants.
