| 摘要 |
A method and a system for in situ measuring and analyzing, in a continuous, non-intrusive manner in real-time, one or more compounds, typically minerals present in debris from drilling or some similar material, in powder, comminuted solids or slurry form is disclosed. The method and system provide real-time, non-intrusive, continuous in situ determination of the grade of valuable minerals present in drilling pits debris generated during excavation, with a relatively low measurement error. |

1. A collection, preparation and analysis system of low error for in situ determination, in a continuous, non-intrusive manner and in real-time, of the concentrations of one or more minerals of interest present in debris from drilling or other sources within geological and mining industry or from any process of extraction and processing of metals, comprising:
a) a debris collection module comprising coupling means for connecting and capture the material as a powder, granular material, comminuted solids, from 0% moisture content to a slurry of 98% of moisture content, from a bit excavating said drilling, a debris transportation media that are connected to a conditioning module, wherein the debris flowing through said debris transportation media is driven either by the same force that evacuates the drilling or by a displacement media; b) debris conditioning module comprising a storage chamber, in which bottom material accumulates by gravity; c) a spectrum acquisition module comprising upward transportation media of material having an angle of incidence between 15° to 90° from the horizontal, which is sealingly connected to the lower portion of said storage chamber passing through one reading area or chamber into an outlet duct, from which the debris is released out of the system, wherein the reading area or chamber comprises some windows transparent to certain electromagnetic radiation, an electromagnetic emitting means comprising a set of photo-emitters or electromagnetic radiation sources radiating with photons the material passing through that reading area or chamber and optical reading means including spectroscopic sensors or detectors that detect and measure the photons absorbed, reemitted or diffracted by the debris circulating through said reading area or chamber, by techniques of atomic or molecular spectroscopy; and d) a data analysis and transmission module comprising data control and adaptation means, a computer media and a communication means, being such data control and adaptation means connected to said electromagnetic emitting means and to said optical reading means. |
