In the gold mining and recovery industry, Ainuosen has recently witnessed a remarkable surge in the sales of its gold recovery activated carbon and resins. This success is attributed to the brand's unwavering commitment to quality, innovation, and meeting the specific needs of the market.

Ainuosen's gold recovery activated carbon is a cut above the rest. Crafted primarily from high - quality coconut husks sourced from Southeast Asia, it undergoes a meticulous multi - step process. This includes carbonization, impregnation, high - temperature activation, crushing, screening, and refining. The resulting product has an amorphous granular appearance. It boasts an impressively developed specific surface area and pore structure, which are crucial for its adsorption capabilities. This large surface area, combined with a pore size optimized for gold adsorption (ranging from 0.5 - 2 nm), enables it to effectively capture gold - cyanine complexes (such as (Au(CN)₂)⁻) in solution. In addition, the ash content is strictly controlled to less than 3%, minimizing interference with the gold adsorption process. The activated carbon also exhibits high strength, with an abrasion resistance strength of over 95% (ASTM standard), allowing it to withstand the mechanical abrasion during stirring or flow adsorption in gold recovery operations.

The brand's resins for gold recovery are equally remarkable. Ainuosen offers a range of ion - exchange resins, each designed with specific functions. These resins act like selective sponges, attracting and trapping gold ions from gold - bearing solutions, which are often derived from leaching processes. They have a high selectivity for gold, which means they can effectively separate gold ions from a complex mixture of metals and impurities in the solution. Compared to traditional methods like using activated carbon alone, Ainuosen's resins may offer better efficiency in gold recovery, potentially recovering a higher percentage of gold from the solution. Some of these resins also have the advantage of being regenerable. After the gold is extracted, they can be treated and reused for multiple cycles, significantly reducing operational costs for gold mining companies.
