Easy Guide to Mining Waste Characterisation - EESI Group

Waste characterisation is the study of the environmental impacts of mining waste during mining, processing and above ground storage of ore prior to treatment. Waste characterisation needs to consider whether the waste will cause: acid & metalliferous drainage (AMD) saline and/or sodic drainage (i.e. neutral mine drainage) leaching and mobilisation of metals and toxic compound

Tailings and Waste Rock - Clean Environment - Cameco ...

Tailings and Waste Rock. Mining at our operations in northern Saskatchewan requires the excavation of rock to access the uranium bearing ore. This waste rock is classified as either mineralized or non-mineralized. Waste rock generated during underground mining is temporarily stored underground before being moved to surface for storage.

Technical Document: Acid Mine Drainage Prediction

Acid Mine Drainage Prediction compares acid rock drainage factors of waste rock piles and tailings impoundments. In examining this table, it is important to note that diffusion of oxygen into water is slow and, therefore, oxidation of iron sulfide is inhibited until the water level drops, which can occur periodically or seasonally in some cases.

Tailings, Waste and Environmental Management - teck

Waste Rock and Overburden: Waste rock and overburden, which is material that is removed to access ores, coal and oil sands, typically contain trace amounts of naturally occurring metals and other constituents. The bulk of waste rock from our operations is placed in areas that are specifically designed to contain the rock.

Aug 30, 2018 · During mining, we will place all waste rock and tailings on engineered liners similar to those used by community landfills or industrial solid waste disposal facilities. During closure, the waste rock will be used to backfill the mine pit. The tailings and any remaining waste rock will be covered and monitored per Michigan's mining regulations.

LECTURE 4: MINING WASTE - sgu.se

The ratio between waste rock and ore production is called the stripping ratio. For example, a stripping ratio of 2:1 means that 2 tonnes of waste rock needs to be mined to mine 1 tonne of ore. Generally, an open pit mine has a higher stripping ratio than an underground mine. Waste rock is often stored close to the mine to minimize transports.

How Is Mining Waste Recycled? - ecocycle.au

How We Recycle The Big Stuff. Rock and soil need to be moved to gain access to the coal, metal ores or other materials of interest. In some situations, it may be possible to sell rock and soil for a range of purposes as it is usually set aside for rehabilitation of the mine site after mining ceases.
