  • Calculations of Solution Concentration ScienceGeek

    Methods of Calculating Solution Concentration. Determine the mass of solute and solution and then divide the mass of the solute by the total mass of the solution. This number is then multiplied by 100 and expressed as a percent. In dilute water solutions, we can assume that 1 mL of water based solution has a mass of 1 gram, so 1 liter of solution has a mass of 1000 grams.

  • Elution and Carbon Reactivation Resource book

    During the CIL process, gold is leached from the ore using an alkaline cyanide solution. The resulting gold cyanide complex ions are then concentrated and separated from the slurry by adsorbing onto activated carbon. Elution is the next step in the process, whereby the adsorption of the gold cyanide complex onto carbon is reversed.
