Mill tailings dumps at Kolar Gold Fields, Karnataka, are creating environmental problems. One of the solutions to these problems is to use the mill tailings for some useful purpose. This study examined the possibility of making bricks from the mill tailings with some additives in laboratory experiments.
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 US40 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.

Experienced gold prospectors know better. No gold mining method is efficient, and this is most certainly true of the old methods used the early miners. On the old bucketline dredges, there are two main reasons for this. If you are searching for a big gold nugget in dredge tailings, the best tool for the job is a metal detector. With a

The tailings dumps were hydraulically mined, reprocessed and stored in an engineered impoundment located 10km south east of Kalgoorlie. From the 60 million tonnes of tailings mined 695,000 ounces of gold was recovered by CarboninCircuit (CIC) and CarboninPulp (CIP) leach and absorption circuits (Kaltails 1998; Normandy 1998).

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water
From the 60 million tonnes of tailings mined 695,000 ounces of gold was recovered by CarboninCircuit (CIC) and CarboninPulp (CIP) leach and absorption circuits (Kaltails 1998; Normandy 1998). Of the 333 hectares of land that was hydraulically mined, 262 hectares will be used for waste rock storage from the Kalgoorlie Consolidated Gold Mines
2015/05/07 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 tailings. DRD Gold extracted 33,600 ounces of gold,

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 reprocessing plant will be re
Hazardous Properties. Toxic chemicals used to extract the valuable materials from the ore, such as the cyanide used in gold mining, remain in the tailings at the end of the process, and may leach out into ground water. Rock may naturally contain dangerous chemicals, such as arsenic and mercury, which leach into water much more readily after rock has been ground up and exposed to the wind and
