The Slurry Pipeline, a €400 million investment, 90 cm in diameter and 187 kilometers in length, has allowed OCP to reduce its transport costs by 90%. Before 2014, large draglines were already digging the earth to find the phosphate layers. Raw phosphate was loaded onto huge trucks to be transported to a screening unit, which separated it …

Abstract. A review is presented on slurry pipeline transportation of minerals and coal. Primary emphasis is put on past commercial applications, technical characteristics of the various pipeline system components, preliminary costing methodologies, and the hydraulic design criteria for both conventional as well as nonconventional slurries.
During the coal boom of the 1970s, slurry pipelines were proposed as an alternative to rail transport. Coal would be crushed, then mixed with water to create a slurry and sent via pipeline to its …
The aim of this paper is to provide a description of construction activities and strategies performed by Techint Engineering and Construction for different aqueous slurry pipelines and facilities. Construction methodologies are discussed for slurry pipelines up to 36 inches in pipe diameter, more than 300 km in length and considering internal ...
slurry, watery mixture or suspension of insoluble matter. In the manufacture of portland cement, a mixture of the raw materials with water is called a slurry. Cement may be piped as a slurry in building construction. Coal may be transported over long distances as a slurry via pipeline; this method of transmission is economical between large ...
A slurry pipeline option is a consideration in studying of alternative modes of transportation for development of mineral, iron ore or coal projects. Long distance transportation of solids by slurry pipeline is an evolving technology which commenced in 1957 with the 172 km Ohio coal pipeline in USA.
Georgia kaolin slurry was pumped at three volumetric concentrations (12.%, 13.7%, 16.6%) through 40.9mm bore PVC pipe, and air was introduced into the slurry flow for a range of air and slurry ...
1. Introduction. Recently, slurry erosion caused by solid particles has received considerable attention amongst researchers, owing to the intensity of the problems it causes to equipment in service, especially for short- and long-distance pipeline systems used for the transportation of slurries containing ores or tailings in mining operations, or …
Dependable, large severe service valves to support remote slurry transport operations. MOGAS was first to successfully introduce metal-seated ball valves in the severe service applications of slurry transport …
For slurry pipeline, it is the concern of the hydraulic engineer to find the shortest route (lower pressure losses), the least slope (for ease in operation and maintenance) and one with most consistent elevation (for low pumping head). The geotechnical specialist identifies possible construction difficulties such as rock formations, river
Slurry pipelines. We design and optimize long-distance slurry pipelines globally, for any type of fluid or material. For effective system design and operation control, our …
The earliest known slurry pipeline transported a gold bearing gravel-water slurry in a California placer mining operation in the late 1850's. In 1889, a patent claim was filed by W.C. Andrews for a slurry system although no record exists of its application, In 1904, coal pipelines were mentioned
Abstract. Extensive field measurements on a dredging installa-tion with a pipeline that is approximately 10 km long and has three booster stations in series, have shown that, contrary to expectations, density fluctuations in slurry flow generated in a system inlet are not flatten-ed. Whilst passing along the pipeline with pumps in series, …

A slurry pipeline is a specially engineered pipeline used to move ores such as coal, iron or mining waste over long distances. According to the task force to draw up the National Infrastructure Pipeline (NIP), "Ministry of Steel has identified four slurry pipeline projects, to be implemented over fiscals 2020-2025 and the total capital ...
The earlier long coal-slurry pipeline is the Black Mesa pipeline in the United States, built in 1970; 18-inch pipeline transports 4.8 million tons of coal per year from Black Mesa, Ariz., to southern Nevada, over a distance of 273 miles very successfully. The World's longest slurry pipeline is at Etsi, USA 1036 km long, 38″dia, and 25 Mt/yr ...
A slurry pipeline option is a consideration in studying of alternative modes of transportation for development of mineral, iron ore or coal projects. Long distance transportation of …
Long-Distance Slurry Pipelines. Jay P. Chapman. Abstract. This work presents the basic information needed to understand the history, the hydraulic concepts, and equipment …
1. Introduction. Pipeline transport of slurries is a matured field (Reference Paterson Paterson, 2012; Reference Thomas and Cowper Thomas & Cowper, 2017; Reference Wasp Wasp, 1983) where solids ('payload') …
Long distance slurry pipelines are widely used in the mining industry and, compared to bulk transport systems, have a good performance record for high-availability, excellent safety, and profitability in transporting mineral concentrates such as coal, copper, iron, phosphates, and oil sands. Mining operations also use shorter pipelines to pump ...
The transport of slurries in pipelines is more complex than that of water, because the particles have to be maintained in suspension, a situation that necessitates turbulent flow …
Advisory supported by engineering. Our involvement with over 20 major long distance slurry pipelines currently in operation provides field tested and practical project lifecycle insights. Best industry practice is continuously validated, we believe continuous improvement is achieved through small changes rather than major paradigm shifts.
Slurry pipelines represent an economical and environmentally friendly transportation means for many solid materials. This paper provides an over-view of the technology, …
The term slurry pipeline has two meanings, one that dates back to the era of collieries, the other more recent and related to the fight against climate change.. Slurry pipelines in coal transport. Under its first definition, a slurry pipeline is a pipe used to transport coal suspended in air or water.This type of slurry pipeline, used in coal exploitation, …
ArcelorMittal completes Rs 2,350-cr acquisition of Odisha Slurry Pipeline Infrastructure. Lenders received the payment last week ensuring recovery of loans that were due for more than five years. Odisha Slurry runs a 253-km long pipeline supplying iron ore from mines to the Hazira plant, which was acquired by the ArcelorMittal-Nippon Steel ...
The head loss (hL) during pipeline transportation of slurries increases with coal ash concentration (ϕ = 0.272–0.349) and slurry velocity (vm = 0.5–3 m/s). hL estimated from the rheological ...
