Arctic Climate Pipeline Design Considerations

April 1, 2020Tech Topics

Over the years there has been an increasing trend for resource companies to develop mining projects in cold regions and areas of permafrost. The arctic presents unique engineering challenges. Many of the sites are in remote areas where road access is difficult. These regions bring about challenges related to labour, equipment, logistics and costs. This … Read More

Optimising Operating Ranges to Control Backfill Variability

March 11, 2020Tech Topics

A paste backfill system seldom operates at a fixed operating point and the system always needs to accommodate considerable variability in materials depending on what ore is being mined and the performance of the process plant. It is therefore important to design a flexible backfill system that accounts for varying backfill rheology while ensuring that … Read More

Optimise Your Backfill Through Particle Size Manipulation

January 14, 2020Tech Topics

The global trend of decreasing metalliferous ore grades and increasingly complex mineralogies is leading to finer grind sizes to achieve the necessary liberation for ore beneficiation. The impact of this is expressed throughout the ore processing cycle, including mine backfill; by leaving lower fractions of coarse material suitable for hydraulic fill and, in particular, influencing … Read More

One Conference, Two Papers and Future Research

December 4, 2019Tech Topics

The 19th International Conference on Transport & Sedimentation of Solid Particles (T&S) was held in Cape Town in September 2019 and it was a great success. It’s the first time the conference has been hosted in Africa since its inception in 1971 and Paterson & Cooke (P&C) co-hosted the event together with Wroclaw University of … Read More

Mine Backfill Forensics – Pastefill Pipe Blockage

November 7, 2019Tech Topics

  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

Operating Slurry Pipelines with a Deposit

September 12, 2019Tech Topics

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

Technical and Cultural Tour: T&S 2019 Conference

September 4, 2019News

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

On-Site Operator Training

July 16, 2019News

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

A Tour of Kidd Mine’s Paste Backfill System

April 2, 2019News

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
