Method and system for automatic recognition of minerals in drillings based on hyperspectral images
The present invention relates to a method and a system for automatic recognition of minerals, that can be integrated for example in an acquisition probe, which analyses in real time the hyperspectral images captured by the probe using a method based on neural networks adapted to hyperspectral images. Said neural networks are trained using a database of hyperspectral images of minerals created by transforming samples of hyperspectral image data from mineral drill core boxes, acquired by heterogeneous hyperspectral sensors.
Hyperspectral imaging device for subsurface exploration
Disclosed is an apparatus for capturing hyperspectral images for subsoil exploration, which analyses images in situ, dispensing with sample collection and analysis. The apparatus comprises: a winchwith an instrument for measuring depth and rate of descent; an acquisition unit connected to the winch by a cable, which comprises a case, with a transparent window at a bottom end and an upper cover with a connector at a top end, connected to the cable; an image-capturing device for capturing images through the transparent window; a lighting device in the case; a control unit in the case, which comprises a storage unit , a positioning unit and a communication unit ; and a power device in the case .
Method of decontaminating metal species in water using caustic magnesium.
The invention relates to the use of a low-cost, highly-reactive magnesium oxide which is available in large quantities in order to eliminate metals from water. The aforementioned material is applied alone or mixed with other inert or reactive products such that the mixture is permeable to the flow of water and acts as a filter. Said material can be installed as a filler in trenches to intercept the passage of water or as a filer in reservoirs and channels through which a surface water course flows. The inventive method makes use of the natural flow of water and an excessive amount of material is applied without the need for the material to be dosed or permanent attention given. The magnesium oxide dissolves thereby neutralising the acidity of the water and stimulating the precipitation of the hydroxides of the dissolved metals.
Method for recovering metals from the flying ashes generated in an integrated gasification combined cycle-type (IGCC) thermal station
The method involves the following steps: a) leaching said IGCC ashes with an extracting agent selected amongst water, an aqueous solution of an acid and an aqueous solution of a base in order to solubilize all or part of the Ge contained in said IGCC ashes; b) separating the solid and liquid phases in the solution or suspension resulting from step a) into a solid phase (S1) and a liquid phase (L1) which contains the Ge and c) recovering the Ge in said liquid phase (L1). The inventive method makes it possible to upgrade the IGCC ashes by recovering the Ge and, optionally, other valuable metals, e.g. Ga, V and/or Ni.
Geoscientific Software & Code Repository
Geoscientific Software & Code Repository (Geo-Soft-CoRe) is an open access multidisciplinary collection for software and code in Earth science. The collected software has been developed to analyze different aspects of the Earth system, encompassing tools for: i) analyzing climate variability; ii) assessing natural hazards, and iii) understanding the solid Earth’s structure and dynamics.
