The process from raw ore to final gold ingot involves multiple stages, including crushing, grinding, beneficiation, leaching, adsorption, desorption, electrowinning, and smelting. In many hydrometallurgical processes for gold, gold in the ore is first leached and converted into soluble gold-containing complexes, then activated carbon is used to selectively concentrate the gold in the solution.

Treat persistent PFOA "forever chemicals" from electroplating, semiconductor & firefighting wastewater. Learn how Zhulin coal-based extruded crushed GAC delivers efficient industrial PFAS removal.

BOD and TSS are critical wastewater limits requiring further removal after biological treatment. Activated carbon filters absorb organics and trap tiny solids to produce clean, compliant effluent.

Nitrogen dioxide is a pervasive and aggressive urban pollutant that is difficult to capture using standard physical adsorbents due to its small molecular size and low polarity. Activated carbon with properly engineered surface chemistry provides a reliable and cost-effective solution for NO₂ abatement. When impregnated with ammonia as a reactive catalyst, the removal capacity of activated carbon increases by an order of magnitude compared to virgin carbon, making it the preferred media for gas-phase NO₂ control worldwide.
