Tailings Management – Dewatering of Slurry Tailings at Disposal Site

Get Report
C2706701/10/2019
Author: Ognjen Orozovic, Thomas Bunn, Craig Wheeler, David Bradney | University of Newcastle

Tailings dams are an essential part of mining, mineral processing and power generation. However, risks including a catastrophic dam collapse mean that tailings dams present serious safety, environmental and social consequences. Most risks, however, can be alleviated through reducing the volume ....  read more

C1804201/02/2012
Author: Götz Bickert & Bernd Länger | GBL Process, Outotec

The background for the project was that Bulga has installed the first paste thickener for coal tailings in Australia.  The paste thickener was installed to thicken tailings sufficiently to handle it on the reject conveyor.  During commissioning and operation it was determined that ....  read more

 

Tailings Management Through Control Of Colloidal Interactions

C1803901/07/2011
Author: Philip Ofori, Anh V Nguyen, Bruce Firth, Clint McNally | CSIRO Energy Technology & School of Chemical Engineering University of Queensland

Handling fines rejects, stabilising tailings dams with a high proportion of clay materials and the emerging problem of availability, quality and cost of water present significant challenges to the coal industry. Effective solutions for these challenges are needed and require an improved ....  read more

C1305227/08/2009
Author: Jan Verboomen, Troy Blagden | Australian Inspection Technologies Pty Ltd

Traditional coal preparation involves a number of wet processing technologies which have been in use for many years. Whilst washing coal has allowed coal mines to provide higher quality product, it comes with drawbacks. Environmental regulations and guidelines are pointing towards a reduction ....  read more

 

Charge Neutralisation for Mechanical Tailings Dewatering

C1504913/05/2009
Author: Peter Purdon | ACIRL Pty Ltd

The stated objective of this project was to demonstrate improved operation of the mechanical dewatering of coal tailings based on charge neutralisation of the feed.

The project demonstrated that belt press filter feed charge demand can be measured using a by-line sampling system, with ....  read more

 

Impact of Flocculant Addition on Tailings Impoundment

Get Report
C1406401/10/2008
Author: Daniel Bembrick | SNF (Australia)

Water retention, water loss and delay in tailings storage rehabilitation is a major challenge for many coal mines. Work by Stewart, Backer & Busch in the early 1980's suggested that there were improvements to be made in tailings dewatering and density by the addition of flocculant. ....  read more

 

2D Classification of Coal: Refining the Segregation using the 2D Classifier

Get Report
C1603701/10/2007
Author: Kurt Liffman, Ben Aldham, Craig Seath, Ilija Sutalo | CSIRO

The goal of this project was to measure the size and density segregation of -2 mm coal powder that had been processed two times by the CSIRO 2D rotational classifier.

Stage 1: The project commenced in early March 2007, when CSIRO received six 44 gallon drums of coal slurry from ....  read more

 

Dry Classification of Fine Coal

Get Report
C1505504/05/2007
Author: KJ Walton, Kevin Galvin, AM Callen | University of Newcastle

The classification and beneficiation of coal with spirals or cyclones inherently involves high water consumption. The issue of water supply, particularly in arid areas, is further complicated by problems associated with waste tailings generation and disposal. The development of ....  read more

 

Technical and Safety Comparison of DP Cell and Nucleonic Density Gauges

Get Report
C1305020/06/2006
Author: Andrew Vince, Ian Brake, Ben Cronin | BHP Billiton Mitsubishi Alliance

In Australian coal processing practice the measurement of slurry density is of critical to medium importance, depending on the application. A number of means are used for measuring density – traditionally nuclear and differential pressure methods. In recent times nuclear methods ....  read more
