Publication number: 20240002306Abstract: The present disclosure, in various embodiments, discloses hydrothermal methods, hydrothermally modified materials and dried hydrothermally modified materials. Certain dried hydrothermally modified materials can readily releases ionic species such as alkali metal ions (K+, Na+), silicate salts, and alkaline earth metal ions (Mg2+, Ca2+). Some dried hydrothermally modified materials can readily release aluminum ions and/or silicon, such as in the form of soluble silicates. Such processes and materials are useful, for example in economically preparing potassium releasing fertilizers.Type: ApplicationFiled: May 17, 2023Publication date: January 4, 2024Inventors: Davide Ciceri, Marcelo de Oliveira, Antoine Allanore, Dennis P.

Publication number: 20210277531Abstract: Various embodiments utilize selective sulfidation and/or desulfidation for such things as ore and concentrate cracking, metal separation, compound production, and recycling. Selective sulfidation can be used to selectively convert an oxide or other material in a feedstock to a sulfide or other sulfur-containing material, and selective desulfidation can be used to selectively convert a sulfide or other sulfur-containing material in a feedstock to an oxide or other material. In some cases, the material produced by such selective sulfidation/desulfidation of the feedstock can itself be novel and/or commercially valuable, while in other cases, such selective sulfidation/desulfidation can be followed by one or more processes to extract, isolate, or concentrate the converted material.Type: ApplicationFiled: December 27, 2020Publication date: September 9, 2021Inventors: Antoine Allanore, Caspar R.
