Understand what are the tailings ponds

Feb 23, 2016Natural moisture ore processing: an innovative and sustainable solution. Another major advantage of the technology is that it eliminates the need for tailings ponds. High-grade ultrafine iron ore particles can be used to make products rather than discarded in tailings ponds. Over the S11D Mine's 30-year lifespan, this will add 300 million metric tons to our output.

CO2 Sequestration of Mine Tailings

Ultramafic mine waste has an inherent but untapped capacity to permanently trap the greenhouse gas carbon dioxide (CO2) thus affording environmental and regulatory benefits through greenhouse gas offsets or trading credits. This project is exploring how to accelerate direct capture of CO2 from the atmosphere and documenting how to incorporate carbon sequestration activities into mine []

20.1 Metal Deposits

Magmatic Nickel Deposits. A magmatic deposit is one in which the metal concentration takes place primarily at the same time as the formation and emplacement of the magma. Most of the nickel mined in Canada comes from magmatic deposits such as those in Sudbury (Ontario), Thompson (Manitoba) (Figure 20.4), and Voisey's Bay (Labrador).

Recovery of Nickel and Cobalt from Laterite Tailings by

We show here that the ferric iron reduction mediated by Acidithiobacillus thiooxidans can be applied to an aerobic reductive dissolution (AeRD) of nickel laterite tailings. AeRD using a consortium of Acidithiobacillus thiooxidans and Acidithiobacillus ferrooxidans extracted similar amounts of nickel (53–57%) and cobalt (55–60%) in only 7 days as AnRD using Acidithiobacillus ferrooxidans.

Mine Tailings

Tailings are distinct from "waste rock", which is the non-ore rock which miners move and discard as they dig down to access the underlying ore. They are also distinct from soil and organic matter (collectively known as overburden ), which is removed from the surface above the ore deposit.

Tailingsfo Dry Stacking of tailings

Introduction. These filtered tailings are normally transported by conveyor or truck, deposited, spread and compacted to form an unsaturated tailings deposit (Davies and Rice 2001).
