SOME ECONOMIC ASPECTS OF MINERAL SLURRY PIPELINING
The subject of slurry pipelining has received much attention by a small group of technical and business people for many years. Although the casual observer may not be able to identify a specific application, we are surrounded by such systems. The most obvious of these is the city sewer system. Other common examples are dredging and well-drilling operations, chemical and other plant process pipelines, and, more recently, bulk materials handling systems. Pipelines are capital intensive and are, therefore, less subject to inflationary pressures. As little as 30% of the slurry transport charge may be related to actual operating expenses. Of this, about half may be attributed to power charges which, historically, have been stable in price. This leaves about 15% of the total transport charge vulnerable to escalations in price for labor and supplies. Pipelines are frequently buried and, therefore, not readily apparent to the general public. This is a definite advantage in today's environmentally conscious society. Pipelines lend themselves to a high degree of automation. This automation is frequently backed by resident operators in remote areas, and the combination of automatic systems attended by competent operators appears to offer the best combination of system availability and minimum personnel requirements.
