WORK CYCLE:
· Add between 25 and 50% of the volume of the distilled water solution.
· Slowly add 50 to 100 gr per liter (over the initial volume, before diluting) of caustic PQ, while carefully stirring, and continue stirring every certain interval of time for one hour.
· After that time all the precious metals present in the solution will have been reduced and will appear forming a dark precipitate.
· Let stand a few hours until the liquid is transparent.
· Separate the grounds by filtration and wash them several times with distilled water (until a neutral PH is achieved).
