20090158894 | METHOD FOR RECOVERING GOLD - The invention relates to a method for recovering gold in connection with the hydrometallurgical production of copper from a waste or intermediate product containing sulphur and iron that is generated in the leaching of the copper raw material. The recovery of both copper and gold occurs in a chloride environment. The gold contained in the waste or intermediate is leached by means of divalent copper, oxygen and alkali bromide in a solution of copper (II) chloride and alkali chloride, in conditions where the oxygen-reduction potential is a maximum of 650 mV and the pH a minimum of 0.5. The bromide accelerates the dissolution of the gold. | 06-25-2009 |
20120318102 | METHOD FOR ENHANCING SOLID-LIQUID SEPARATION IN CONJUNCTION WITH LATERITE LEACHING - The invention relates to the hydrometallurgical treatment of laterite ores in order to recover valuable metals. More specifically, the invention presented relates to a method for improving precipitation and solid-liquid separation in conjunction with the leaching of laterite ores. According to the method the slurry exiting the leaching of laterite ores is neutralised, after which part of the slurry is routed to solid-liquid separation. Iron is precipitated from the solid-liquid separation overflow by neutralising the solution and the solution that is formed, which includes jarosite seeds, is routed to an appropriate point in the process to control the precipitation of iron and to enhance the filterability of the solids. | 12-20-2012 |

20130203173 | Method for determining the concentration of beta-D-glucan - Method of selectively determining the concentration of beta-glucan in samples, in particular in liquid samples of cereal origin, and a kit for such analysis. The method comprises the steps of contacting of a beta-glucan containing sample and a dye in liquid phase, complexing the beta-glucan with the dye to provide a modified liquid phase, measuring photometrically the absorbance of the modified liquid phase, and determining the concentration of beta-glucan based on the absorbance of the modified liquid phase. According to the invention, the dye comprises a Calcofluor dye such as Calcofluor White or Calcofluor White M2R. It has been found that the same reagent, or reagent of the kind basic kind, gives the same result when the sample is measured using photometry as when the dye is used in a reaction wherein fluorescence is measured. | 08-08-2013 |
