செயல்படுத்தப்பட்ட கார்பனின் செயல்திறன் குறைவதற்கான காரணங்கள்

Indeed, the reduction of performance of கார்பன் can have an extremely wide number of causes:

• Contamination/fouling of the carbon by mineral or organic matters present in the ore or brought in by the additives, water or pollutants

• Preg-robbing ore competing with the carbon in adsorbing the gold

• Attrition of the carbon with the propellers, screens and carbon transfer systems

• Poor acid washing efficiency not removing minerals properly from the loaded carbon

• Poor regeneration techniques not removing organics properly

• Extreme temperature changes in the regeneration -quenching stage, leading to breakage of the carbon

Constant monitoring and small modifications to the regeneration kiln’s operating parameters (temperature/throughput), acid washing practices and carbon transfer technologies, will generally overcome most of these problems, and restore the carbon to its optimum.
