Abstract:Chemical extraction of gold by traditional cyanide leaching process was toxic and dangerous, and therefore the development of non-cyanide leaching process was quite important in industry. Bromide salt had been studied to leach and recover gold for many years, while how to enrich the trace concentration of gold from bromide solution was a big challenge. In present study, pomegranate peel was proposed as biosorbent to extract gold from solution, and main parameters like pH value, contact time, temperature, bromide concentration on extraction of gold were investigated. The results is beneficial to improvement gold extraction from bromide solution system.
