Leaching of iron

Sep 13, 2021 In order to remove phosphorus element from steelmaking slag and decrease iron loss, malic acid was selected as the leaching agent to dissolve steelmaking slag. Firstly, the influences of different factors, such as malic acid concentration, slag particle size, temperature, liquid/solid ratio and stirring speed, on the leaching ratios of phosphorus and iron were studied. Then, the kinetics for

    The Effect of Leaching on Iron Levels in Soil

    One key factor that influences soil pH, and consequently iron levels is the process of leaching. Leaching is the process of washing away nutrients and other dissolvable substances from soil by adding large amounts of water to the soil. The factors that influence leaching are

    Selective leaching, also called dealloying, demetalification, parting and selective corrosion, is a corrosion type in some solid solution alloys, when in suitable conditions a component of the alloys is preferentially leached from the material. The less noble metal is removed from the alloy by a microscopic-scale galvanic corrosion mechanism. The most susceptible alloys are the ones containing
