Resumen

The advantages of the SERPENTINE reactor include a hermetic process free of odors, high precipitation rate of copper and silver (99%), compact treatment facility, relatively low operation cost, the precipitate is a saleable copper/silver product, the main advantages of using the SERPENTINE is the low energy that is used and finally, the industrial operation of the SERPENTINE produce high grade copper sulphide precipitate in the range of 40 to 55% of Cu with 130 g/ton Ag and recoveries of cyanide of 80%.
Removal of lead hydroxides and cadmium cyanide ions from cyanide liquors through adsorption on cow bone powder (Ca10(PO4)6(OH)2) is a new approach for cleaning the precious precipitate from plumbite and cadmium ions.
Cow bone powder (CBP) has a high removal capacity for divalent heavy metal ions like lead and cadmium and is also an economical and natural source of phosphate.
This study shows that cow bone powder can be used as a new adsorbent material, capable to remove lead and cadmium ions from cyanide solutions. It has the ability to compete to the other existing commercial adsorbents for the removal of lead and cadmium.
