New approaches for extracting and recovering metals from

Mine tailings may contain base transition metals, such as iron, copper, nickel and zinc, in relatively high concentrations, and also occasionally precious metals such as gold and silver, in minerals (and native metals) that have been not been separated by froth flotation (e.g. Bryan et al., 2006, Ahmadi et al., 2015).

The metallurgical process DRDGOLD

Traditional recovery. Tailings retreatment in South Africa began in the 1970s incorporating a technique known as flotation to recover pyrite uranium and gold. A CIL circuit was later added to enhance gold production. Three decades had passed before DRDGOLD acquired the Brakpan plant in 2007 with the aim of reestablishing the Ergo project.

From Tailings to Treasure? A New Mother Lode

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. It expects to recover 58 kg of gold per month, and has enough slimes to last until 2025.

Factors affecting Gold Recovery from Secondary Ore Tatenda Chingosho, Oluwagbenga T. Johnson, Member, IAENG, and Melvin Mashingaidze Abstract The basis of this study is that significant amounts of gold exist even in the mass regarded as tailings from earlier gold processing steps. The cyanide concentration, residence time and lixiviant pH

Gold Extraction from Tailings and mine waste

Gold 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 the mineral content of the tailings.

ReProcessing Gold Tailings in South Africa sgs

REPROCESSING GOLD TAILINGS IN SOUTH AFRICA CHRISTOPHER A. FLEMING, JAMES A. BROWN SGS AND MARIUS BOTHA by these historic tailings. The first step in the process involves a mildregrind and mild acid leach of the tailings (pH 2.5 to 3.0) to dissolve up pulp for gold recovery. The rougher float tails may be further
