BAT Reference Document (BREF). The Reference Document on Best Available Techniques for the management of tailings and waste-rock in mining activities covers activities related to tailings and waste-rock management of ores that have the potential for a significant environmental impact. In particular the work sought out activities that can be considered as examples of “good practice”.

Our responsible management of mine tailings and waste rock

Our responsible management of mine tailings and waste rock In addition to the ore, mining activity involves extracting a substantial amount of waste rock. Managing this mining waste responsibly and safely is of the utmost importance for the environment.

Tailings and Waste Management Why are tailings and waste management important? Mining operations generate waste that can be in the form of waste rock, processed ore, tailings or sludges. Management of tailings facilities is a global priority for the mining industry, governments, and communities. If not managed properly, this waste can negatively impact the environment []

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.

Tailings Wikipedia

Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed.. The extraction of minerals from ore can be done two ways: placer mining, which uses water

Tailings and waste rock: guide to reporting Canada.ca

The composition of the tailings is shown in Table 3. Waste rock. The operating permits do not specifically address the classification of waste rock for this mine, but as the sulphur content of the waste rock is below 0.2%, reporting of most substances in the waste rock is not required.

Tailings, Waste and Environmental Management

Hazardous Waste and Non-Hazardous Waste: Although a very small volume relative to our tailings and waste rock, we treat our other waste management responsibilities with equal focus. Hazardous and non-hazardous wastes are segregated and disposed of in accordance with material-specific waste management plans and regulatory requirements.

Co-disposal of waste rock with tailings – Mine Closure

The mutual ratio of waste rock and tailings affects to the properties and behaviour of the mixture and its suitability for co-disposal (Table 2). The success of e.g. the co-disposal as homogenous mixtures (good physical and chemical stabilities) depends on the mixture design (Wickland et al. 2006).

Tailings Management Teck

Sep 10, 2020· Tailings and mine waste rock are common by-products of mining practice. Tailings facilities are historically well managed with very few incidents; however, a tailings incident has the potential to have a significant impact on communities, local economies and the surrounding environment.

Mill Tailings Total waste (rock waste and mill tailings) produced during extraction and beneficiation of minerals can range from 10% of the total raw material removed from the earth for potash to more than 99.9% for gold. Table 1 illustrates the amount of amount of waste various mining industries produced in 1992 (Bureau of Mines 1992).

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.

Tailingsfo Co-disposal of Tailings

Examples are waste rock end dumped into a tailings facility, or waste rock used to create internal berms or retaining walls of a tailings facility. Co-deposition Very similar to co-placement, but the waste streams are generally placed in independent layers allowing the deposited tailings to naturally enter the voids in the underlying rock.

Tailings Management The Mining Association of Canada

Responsible management of tailings is an important focus of MAC and its members. Tailings are an unavoidable by-product of mining, consisting of the processed rock or soil left over from the separation of the commodities of value from the rock or soil within which they occur.

STANDARD GUIDANCE (COP 37) Tailings and Waste Rock

Waste rock management basically involves its removal and storage, which may be temporary or long-term. Some mine tailings and waste rock do not pose exposure risks and so do not require special treatment, reuse restrictions or geochemical monitoring. Such wastes can be used for landform reconstruction, road and dam
