journal about gold processing Making Gold Green: New Non-Toxic Method for Mining Gold May 14, 2013· The new process also can be used to extract gold from consumer electronic waste.
Abstract. This paper reviews the state of the art in processing and extraction of gold. The ore bodies which were considered uneconomical at one time are becoming economical due to new and advanced methods of extraction. The paper discusses the gold treatment methods on free milling ores with conventional cyanidation and refractory ores with direct

About 75% of gold extracted from ore is currently processed using cyanide or mercury, which are toxic to humans and the environment. These chemicals are often contained in large storage tanks and, once used, expelled into large tailing dams that can potentially leach into the local surroundings.
