The general recovery rate of gold processing and melting is 80.4%. The general recovery rate of silver processing and melting is 38.2%. The value of tailings is brought into full play, and also brings efficiency to the processing plant. 2. A tailings pond in North Korea stored more than 10 million tonnes of gold tailings.

Gold CIL Leaching Processing Plant

Gold CIL leaching process is an efficient method for extracting and recovering gold from rock gold and gold tailings. By adding activated carbon to the slurry and simultaneously leaching and adsorbing gold, it include leaching pulp preparation, cyanide leaching, activated carbon adsorption, the electric shock to get gold mud, to take off the gold charcoal recirculation,

Re-Processing Gold Tailings in South Africa

historic gold tailings dams in the Witwatersrand area of South Africa is being investigated. The objective is to recover uranium and residual gold from the tailings, as well as to oxidize the sulphides to eliminate long term environmental liabilities associated with acid mine drainage. The tailings from the re-processing plant will be re-

In addition, according to different particle size requirements, the gold tailings particles can be used directly as coarse and fine aggregates for concrete without processing, which makes concrete have higher strength and better durability.

What are Tailings Society for Mining, Metallurgy

Tailings are a by-product of mining. After ore containing an economically-recoverable commodity is mined from the earth, that commodity is extracted in a processing plant or mill. After the commodity of value is extracted from the ore material, the resultant waste stream is termed “tailings”. Typically, mill tailings range from sand to silt
