Thickening or dewatering may be defined as the removal of a portion of the liquid from a pulp or slime made up of a mixture of finely divided solids and liquids. The early methods of thickening employed plain, flat-bottomed tanks into which the pulp was fed until the tank was full. The solids were then allowed to settle as long as required, the top liquid was decanted, the settled solids were ...

By 1917, the shaft at the Argonaut had reached a depth of 4,300 feet. During this period, Argonaut operations were in full swing. That same year, Wilton E. Darrow, owner of the California Slimes Concentrating Company, entered a lease agreement with the mining company to process the tailings from the new mill and built a cyanide plant between the mill and the Eastwood dam.
•yanide recovery by direct acidification C of tailings, followed by volatilization . and reneutralization of the HCN gas (known as the AVR process) is very much faster and more efficient from solution than from pulp, requiring lower volumes of air flow per unit volume of tailings treated and smaller equipment.

No option to store water within a dry stack facility. A conventional tailings facility, designed to store water, can provide a mining operation with a buffer (e.g. storm water storage) to maintain operations during dry months of the year. Oxidation of sulphides in the tailings can create high concentrations (but low volume) of seepage water.

New technology allows it to recover up to 40% of the gold left in particle form in tailings. DRD Gold extracted 33,600 ounces of gold, worth nearly US$40 million, in the last quarter of 2013. Mintails, a mine tailings processor, has developed new technology to process 350,000 tons of slimes from its extensive tailings resources.
mining regions; the dewatering process can capture as much as 90 percent of the water for reuse. Dry tailings Dry tailings are typically achieved through a multi-step process. The sludge is thickened or concentrated through gravity settling in a thickener. The thickener is a conical bottom vessel equipped with scraper paddles that
