DRD Gold, one of the first South African companies to abandon traditional mining to focus on extracting gold from tailings. New technology allows it to recover up to 40% of the gold left in particle form in
Gold ore Extraction From Tailings. Star Trace has been providing a standard technique for extracting the mineral contents from the mining tailings. Star Trace will start the process by sample testing through
15/05/2017#0183;#32;A twostage mineral leaching and metal recovery protocol was developed to extract copper from tailings generated as waste materials in two mines currently operating in Spain and Serbia. The most effective extraction of copper (84 to gt;90%) was achieved by bioleaching the tailings at 45 #176;C, using a defined microbial consortium, where elemental sulfur was added to the tailings and the pH of
Several efforts are underway to extract gold and copper from tailings. Reprocessing mine tailings may also have environmental benefits. A recent project described in is a series of experiments

Xinhai usually adopts the allslime cyanidation + CIP in the gold extraction from old tailings. The gold tailings after cyanidation are treated by dry stacking. That is a technology that recycles the filtrate to
mercury is required to extract one gram of gold. However, tailings from this process are often repeatedly run through the ball mills. Each time more auriferous, or goldladen, mercury flour is produced. Though less mercury escapes by this method, this type of amalgamation is also a significant source of pollution and loss of gold. Table 2 shows analysis of tailings in Tanzania which had been
