Cyanide properties make it indispensable in the mining industry especially for gold recovery. The resultant wastewater generated is discarded to tailing ponds. Any leakages or total collapse of tailing ponds can result in the contamination of surface water bodies; endangering aquatic organisms’ and humans’ alike. The over reliance on physical and/or chemical treatment methods for cyanide wastewater treatment is not sustainable due to high input costs and the generation of by-products. A feasible alternative treatment method for cyanide contaminated wastewater is the biodegradation method, as a wide range of microorganisms can degrade cyanide. In this study, the cyanide biodegradation ability of Fusarium oxysporum was assessed in two stages.......

This code enforces the treatment or recycling of cyanide-contaminated wastewater. Industries such as those involved in mineral processing, photo finishing, metal plating, coal processing, synthetic fibre production, and extraction of precious metals, that is, gold and silver, contribute significantly to cyanide contamination in the environment through wastewater. As fresh water reserves throughout the world are low, cyanide contamination in water reserves threatens not only the economy, but also endangers the lives of living organisms that feed from these sources, including humans. In the mining industry, dilute cyanide solutions are utilised for the recovery of base (e.g. Cu, Zn, Ni, etc.) and precious metals (e.g. Au, Ag, etc.)......

They are particularly recalcitrant due to their molecular weight, hydrophobic nature and thus, accumulate in various matrices in the environment.
