Unified Fines Method for minus 44 micron material and for Particle Size Distribution

A Fines Measurement Working Group (FMWG) consisting of industry practitioners was created by COSIA, and supported by personnel from the AER, to carry out and direct work to develop the standard method contained in this document. The mandate of this group, with input from AER, was to develop a technically accurate and effective method of measuring mineral solids less than 44 microns in size, with incidental benefit to overall particle size distribution.

Guidelines for Determining Oil Sands Fluid Tailings Volumes

This guideline sets out procedures for determining the volume of fluid tailings contained within tailings deposits. It is intended to provide guidance to operators of oil sands mines to meet the objective of controlling fluid tailings volumes to an approved plan consistent with the Tailings Management Framework for the Mineable Athabasca Oil Sands (TMF).

A Geostatistical Study, Workflow and Software Guide for Tailings Deposit

Estimation of fines and solids content in tailings oil sands deposits is imperative for tailings planning as well as reporting tailings inventory to the regulator. Data obtained from a finite number of sampling locations are the main source for estimating the quantity of fines and solids in the deposits. To date, the required number of sample locations or spacing to estimate tailings volume/mass with reasonable confidence is not well defined. The Geostatistics and sampling working group (GSWG) of Canada’s Oil Sand Innovation Alliance (COSIA) took over the task of defining the sample spacing for predicting tailings inventory with “reasonable confidence”. Development of a proper procedure for the engineering assessment of uncertainty in reported tailings mass/volume as a function of data spacing was the main objective of the task.

Guidelines for Tailings Deposit Sampling and Measuring Tools

The purpose of this work is to propose standardized field sampling methods for the determination of the characteristics of oil sands tailings deposits which will allow the gathering of technically and statistically defendable results required for AER reporting. It is desired to adopt/develop a standard sampler used by the industry and to develop accuracy charts for each tailings deposit sampled by the standardized tool.

Deposit Characterization

This report provides the results of the Deposit Characterization Working Group, which was tasked with identifying and recommending a standard method for measuring the in situ undrained shear strength (or appropriate equivalent measurement methods) for all tailings deposit types that are technically and statistically appropriate for AER reporting.

Guidelines for Performance Management of Oil Sands Fluid Fine Tailings Deposits to Meet Closure Commitments

The purpose of this document is to provide oil sands mining operators with guidelines for creating fluid fine tailings (FFT) management plans, consistent government policies and regulations, facilitating closure of oil sands mines by accelerating the conversion of FFT into stable closure landscapes.

Beach Fines Capture Study

Obtaining an enhanced understanding of the processes controlling fines capture in beaches could lead to implementation of operational changes that would increase beach fines capture and reduce the amount of fines forming fluid, resulting in smaller quantities of mature fine tailings (MFT).
