Goethite with a wedge, prismatic or bead-type micro-structure has a higher adsorption of silica (2 – 4%), while goethite having an intergranular, bead or prismatic microstructure …
The kinetics and reaction mechanism of the goethite …
At early stages and lower temperatures, the mechanism is one of proton/iron transfer across the reaction interface. Important goethite characteristics are grain size, …
Goethite is the source for the pigment known as yellow ochre; it is also the primary mineral in some important iron ores, such as those in the Alsace …
