Despite the best intentions during the engineering and design phase, things can go amiss in a pastefill system and the pipeline ends up becoming plugged. The first step is to safely empty the boreholes as quickly as possible and attempt to clear the line with water. After ‘saving’ as much of the system as … Read More
Slurry pipelines are conventionally designed to operate without a deposit on the pipeline invert – i.e. the minimum operating velocity is greater than the deposition velocity. Largely this approach has been adopted due to concerns regarding potential blockage of a pipeline operating with a deposit. A typical slurry pipeline design duty envelope is shown in … Read More
Delegates to the 2019 Transportation & Sedimentation Conference will be treated to a technical tour of the Slurry Test Facility at Paterson & Cooke’s premises in Pinelands on Thursday 26th September. Our 1 200 m2 test facility includes large scale slurry pump and pipeline test loops of up to 300 mm in diameter, viscometers, thickening … Read More
Sharing knowledge has always been part of Paterson & Cooke’s culture and as far back as 1995 we began presenting our well-known course on slurry pipeline design to inform our clients in the mining industry on the latest slurry pipeline technologies. This proved to be a great success and continues through our annual courses on … Read More
The 19th International Conference on Transport & Sedimentation of Solid Particles will be held in Cape Town from 24 – 27 September 2019. The Cape Town Hotel School, situated close to the popular V&A Waterfront precinct, will be the venue. The conference has become a place for scientists, engineers and leading authorities in the field … Read More
On Friday 29 March 2019, many of the delegates to the Paterson & Cooke Backfill Course held in Sudbury, Ontario, travelled to Timmins, some 290 km away, for a tour of Glencore’s Kidd Mine paste backfill system. Visiting both the plant and the underground distribution system brought the concepts discussed during the course to life. … Read More
For the first time since its inception in Poland in 1971 the International Conference on Transport & Sedimentation of Solid Particles will be hosted outside of Europe. Cape Town, South Africa is the host city for the 19th International Conference, which takes place from 24 – 27 September, 2019. Peter Goosen from the Cape Town … Read More
Josh Stowe from our Denver office will be presenting a paper at the SME Conference in Denver entitled NEW APPROACHES AND TECHNOLOGY FOR TAILINGS PIPELINE DESIGN AND OPERATION. The conference is being held at the Colorado Convention Center from 24 – 27 February 2019. The paper was co-written by Josh and Dr Robert Cooke. J. … Read More
Triaxial testing represents international best practise for determining the important geotechnical parameters of shear strength and cohesion of soils. These parameters are important to uncemented backfill applications, but have also in recent years become important parameters for cemented backfill applications with the increased use of computational modelling and simulation. The test apparatus also allows for … Read More
Dr Angus Paterson, a founding member of Paterson & Cooke, will be presenting two papers at the 6th International Mining & Industrial Waste Management Conference being held in Limpopo, South Africa from 29 – 31 October 2018. Here’s a little taste of what’s in these two papers. Comparison of the Pumping Requirements of Conventional, Thickened … Read More
