TL;DR: The dissolution of synthetic magnetite, maghemite, hematite, goethite, lepidocrocite, and ak- aganeite was faster in HCI than in HCIO4.

TL;DR: In this article, the authors studied selected chemical, physical and mineralogical properties of seven soils, ranging from the Tertiary Plateau down to the Amazon river floodplain in the Iranduba district, near Manaus, Amazonas, Brazil Three Terra Preta soils were classified as anthropogenic (Anthropic Xanthic Kandiudult, Anthropic Xantha kandiudox and Anthropic Dystropepts) Chemical, mineralogical and micropedological attributes, such as high total and available P and mica flakes in pottery remains found

TL;DR: In this article, the dissolution of 39 soils derived from various parent materials in south-western Australia have been studied using a variety of techniques using a Cube Root Law and by Kabai's equation.

TL;DR: In this paper, a review identifies previous research where the agronomic effectiveness of ground rock fertilisers has been evaluated and identifies the contradictory findings that need to be evaluated by reference to basic geochemical knowledge.

TL;DR: In this article, the acid buffering behaviour of red muds was investigated by incubation of acid-treated red mud with various amounts of hydrochloric acid and showed that sodalite and calcite buffer (i.e. dissolve) simultaneously.
