mine tailings and the carbon-in-pulp (CIP) process were obtained from selected key areas in Mindanao, Philippines. The results showed that mercury use is still prevalent among small-scale gold miners in the Philippines. Tailings after ball mill-gravity concentration
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.
Reprocessing of tailings materials offers an economical opportunity for ... The effect of the pH regulator types was taken ... and the net neutralization potential (NNP) of the mill tailings.
Tailings of our focus were recovered from effluents after their settling in view to separate out the mill wastewaters. The chemical analysis of tailings was achieved through dissolution (15 min) of a representative sample (1 g) using a leaching liquor consisting of 10 mL of nitric acid (65% w/w) and 2 mL of hydrogen peroxide ( w/w), dilution (1:10) and …
Reprocess tailings. Really? Yes, really. If the technology exists today to remove up to 90% of water from mine tailings and, if a mining company is going to make that investment anyway to secure its future operations, then frankly, it is irresponsible not to consider reprocessing the tailings that currently sit in its TSFs.

New Tailings Reprocessing Technology Has Environmental Benefits. Tailings, mineral waste products produced by mining operations, are a well-known pollutant requiring remediation. Tailings may be dumped in or near water or transported by wind or water to contaminate the surrounding area. Mine sites typically manage tailings by constructing ponds ...
Xinhai gold tailings reprocessing technology is mainly from environment protection and full utilization of resource, reprocessing the valuable gold tailings. According to the different characteristics of gold tailings, the reasonable gold tailings reprocessing technology is designed to make the tailings give full play to the value.
There are mainly several methods of gold tailings reprocessing: 1. The iron recovery from gold tailings can adopts common processing technology such as gravity separation, magnetic separation, flotation, roasting magnetic separation and their combined processing technology.
