Abstract
Slurry and paste (highly concentrated slurry) transportation in mining industry are overviewed. In the case of slurry, three types of trends are noticeable. Firstly, long and large capacity pipelines have been constructed to transport concentrates of various ores. Secondly, to protect pipelines from abrasion and corrosion, newly constructed pipelines are lined with high-density polyethylene (HDPE). Thirdly, pipelines from mines at high elevation over 4,000 m have been constructed. These pipelines are controlled by state of art technologies to prevent slack flow and over-pressure.
Paste technology in mining industry is getting popular all over the world. At early stage of the paste technology, mining engineers paid attention to use this technology for back filling inside mines. Recently this technology is applied to surface disposal of paste without using conventional dams or ponds
