Tailingsfo Hydraulic Mining of Tailings

2021-1-4 Some tailings impoundments are hydraulically mined to not just process the tailings but to re-site them for environmental reasons. This is an affective method and can take a shorter time than mechanical excavation, depending on the density and particle sizes of the tailings.

Mine Tailings Disposal Methods - 911 Metallurgist

2017-6-16 In the past, mill tailings have been discharged onto hillsides or directly into lakes or streams. These practices are now prohibited by state and federal laws. Today, the universal disposal method for tailings is the tailing pond. Tailings are slurried with water and pumped to tailing ponds for settling.

Hydraulic Mining - The future of tailings management

2012-9-3 Hydraulic mining allows cost-effective and environmentally sustainable management of tailings, for most sectors of the Australian mining industry. “This method can be used on anything soft, from beach sands to clay,” said Dave Prentice, Operations Manager of HMS.

Hydro Mining at Sibanye Gold’s Randfontein Tailings

At the Lindum dam, the INTASOL team is taking a two tiered approach of hydraulically cutting off the top, sterile section of the dam in order to hydro mine the gold tailings below. Meticulous planning and co-ordination ensures that we remove and pump the top sections to a pit area, while we efficiently hydro mine the lower sections that have been exposed.

Tailings are part of virtually any mining/refining process. Tailings are the stream of unwanted residuals of mined ore that are deposited (usually hydraulically) in large storage dams adjacent an operation. If not managed correctly they can become unsafe, high risk structures that create legacy issues for local community and the environment. ...
