Waste rock and tailings Waihi Gold

tailings are a slurry of around 30 solids and are deposited from the crest of the waste rock embankment via a series of spigots. fresh tailings are deposited above water onto previously placed tailings. the material is predominantly silt size, but also contains clay and sand sized particles. immediately adjacent to the point of deposition into,waste rock dumps guidelines,waste rock characterisation before construction of the waste dump commences, it is essential to know what types of material will go into the dump, so their location within the dump can be planned. the following materials should be appropriately encapsulated within the dump those with acid rock drainage (ard) potential

the particle size distribution (psd) of a waste rock material will be naturally variable due to spatial variation in the material properties and drill and blast practices. the challenge at a feasibility level study stage is that there is typically no blasted waste rock available and hence psd testing on actual materials is not possible. in,user guidelines for waste and byproduct materials in,mar 08, 2016 gradation waste rock is generally coarse, crushed, or blocky material covering a range of sizes, from very large boulders and rocks to sand-size particles and dust. waste rock can be crushed and screened for use or blended with other aggregates to generate a product suitable for granular base or subbase aggregate.

Rockfill Earthfill Material Definition

the segregation of fine rock material sizes at the top to coarse rock material sizes at the bottom of the thick lifts made it difficult to determine a representative gradation size for the overall rockfill lift thickness. examples of rock segregation on stockpile and fill slopes can be seen in photos 1 and 2, respectively.,mine waste transfer and disposal methods mine,waste rock or overburden refers to the often large mass of initial soil and rock that is removed to get to the valuable mineral deposits. typically, for every ton of ore that is mined, 5 tons of overburden is displaced.
