Enhance Gold Recovery with Innospec’s DEHSCOFIX® DG30 Carbon Blanking Agent

In mineral processing, preg-robbing is a significant challenge, especially in gold extraction. Preg-robbing occurs when carbonaceous matter in the ore adsorbs the gold cyanide complex, Au(CN)2-, from the solution. This process reduces gold recovery rates, as the active carbon in the ore competes with the activated carbon added to the leach process, leading to increased gold loss to tailings.

Innospec’s DEHSCOFIX® DG30 Carbon Blanking Agent provides an effective solution to combat preg-robbing. This advanced agent blinds the carbonaceous matter that would otherwise adsorb dissolved gold during cyanidation. By adding DEHSCOFIX® DG30 before slurry conditioning for pH adjustment, the preg-robbing carbon is rendered inactive, significantly improving gold recovery rates.

Benefits of Using DEHSCOFIX® DG30

Increased Gold Recovery: DEHSCOFIX® DG30 ensures that more gold remains in solution, available for recovery. This leads to higher gold yields from the ore, maximising profitability in the extraction process.

Ease of Application: DEHSCOFIX® DG30 integrates seamlessly into existing mineral processing workflows. It is added before slurry conditioning for pH adjustment, requiring no significant modifications or additional equipment.

Non-Flammable: DEHSCOFIX® DG30 is non-flammable, reducing fire hazards and ensuring a safer working environment for plant operators and staff.
