Spatial Distribution Of Heavy Metals Around The Gold Mine
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.Oct 01, 2020 Gold ore tailings can be used as a siliceous raw material for cement production. • The cement phases are 3CaO SiO 2, 2CaO SiO 2, 3CaO Al 2 O 3, and 4CaO Al 2 O 3 Fe 2 O 3. • The hydration products are portlandite, calcium silicate hydrate, and ettringite. • The optimum addition of gold ore tailings in cement production is 5 wt . •.
