US-based cleantech supplies development firm Itronics has developed a Rock Kleen course of that permits restoration of silver and gold from silver-gold leach tailings, by the mixture of Rock Kleen liquid and standard gold restoration applied sciences.
Residual treasured metals, together with silver and gold, base and ferrous metals, nutrient supplies, and industrial minerals might be recovered utilizing the disruptive Rock Kleen expertise from ‘sub-ore grade’ mine tailings.
Touted as a zero waste, vitality saving expertise, the method additionally neutralises full residual cyanide, used within the unique mining course of, rendering tailings cleaner than they have been previous to processing.
Itronics president Dr John Whitney stated: “The brand new expertise has the potential to unlock an infinite quantity of worth from mine waste supplies that presently have both a zero worth, or a unfavorable worth resulting from environmental safety necessities and associated prices.
“This potential financial profit is likely one of the options that makes the Rock Kleen Know-how actually revolutionary.”
Rock Kleen may also recuperate a excessive proportion of residual silver and gold from silver-gold mine tailings. It could possibly additionally recuperate residual nitrogen and the vital minerals manganese, magnesium, and potassium.
The brand new processing idea, which has been developed as an outgrowth of laboratory testing accomplished just lately, neutralises cyanide after use and leaves no cyanide residuals on the rock.
The testing was carried out to analyse the leaching capabilities of the Rock Kleen expertise.
In response to Itronics, as indicated by a preliminary financial modeling of potential Rock Kleen initiatives, the expertise can considerably improve the greenback worth of every tonne of rock processed in comparison with standard processing expertise.
The expertise might have the potential to increase the financial lifetime of current mines.
