Mining Activated Carbon
Activated carbon is a key material in the mining industry, particularly in the extraction of gold and silver through Carbon-in-Pulp (CIP) and Carbon-in-Leach (CIL) processes. In these hydrometallurgical processing methods, the ore is leached with a cyanide solution that solubilizes the precious metals to make a pregnant solution that passes through activated carbon which has a strong affinity to adsorb the gold-cyanide complex on its porous surface. The gold loaded carbon is then separated from the slurry and processed to strip or elute the metals producing concentrated solutions for the recovery process and the carbon can usually be reactivated and reused.
On top of the recovery of precious metals, activated carbon can also be applied in the mining industry in the way of environmental remediation. Activated carbon can be used to treat wastewaters that contain contaminants such as mercury or organics as well as residual cyanide through the adsorptive capacities prior to discharge or recycling of water allowing operations to meet regulatory as well as environmental objectives while mitigating environmental impact. The high uptake capacity of activated carbon also makes it crucial for natural resource recovery as well as closure/progressive land rehabilitation in regards to remediation of contaminated sites.
activated carbon for gold recovery
Activated carbon is crucial to modern gold recovery, especially in Carbon-in-Pulp (CIP), Carbon-in-Leach (CIL), heap leaching and Carbon-in-Column (CIC) processes. Activated carbon has a very strong capacity for the gold cyanide Au(CN)₂⁻ complex removing it by adsorbing it from cyanide leach solutions or slurries.
Metal Removal Activated Carbon
Activated charcoal is mainly used in emergency medicine as a treatment for acute poisoning or overdose. When ingested orally shortly after the patient has taken the poison (generally within 1-2 hours), the very porous surface area of charcoal will...
