The solution strips away the gold and is collected in a pond, then run through an electrochemical process to extract the gold This method of producing gold is cost effective but enormously wasteful: 9999 percent In the processing of Reef the gold is extracted and goes to form bullion (gold bars), whereas the residue has to be disposed of, hence the dumps The early methods of gold extraction would send the tailings (discard) to sand dumps, but as time went by improved methods of extraction would create a slime that could be disposed of by Where have all the mine dumps gone?
