The least energy and water cost condition for turbulent, homogeneous pipeline slurry transport
(Elsevier, 2016)
The efficient combined use of water and energy in long distance slurry pipelines is analyzed in light of the total cost function resulting from an energy and mass balance. Given a system throughput and a set of common ...
A influência de algumas variáveis sobre a reologia de polpas minerais
(Universidade Federal de Minas GeraisUFMG, 2009-06-15)
The study about slurrys rheology behavior has been showing a great importance due to the utilization of ores more and more slender. Nowadays, the slurry is present in several stages during processing due to the poor ore ...
