HERNANDEZ-RAMIREZ, Gabriel et al. Influence of solids concentration on the load-capacity correction coefficient of lateritic hydro mix tansport. Min. Geol. [online]. 2021, vol.37, n.4, pp. 445-460.  Epub 31-Dez-2021. ISSN 1993-8012.

The influence of solids concentration in load-capacity correction coefficient of lateritic hydro mixes of the pumping system was analyzed for an effective and efficient operation to work with pressure acid technology. The power, load and pump performance were modeled when handling lateritic hydro mix with interactions and characteristics of the phases, which make it possible to determine performance and rheological characteristics of the analyzed samples. It is concluded that using a mathematical model for correcting the coefficient obtained experimentally; which relates concentration of solids with energy parameters of the pumping system, will allow evaluating technological improvements in acid pressure leaching, such as the direct preparation technology, which achieves higher concentration of solids.

Palavras-chave : rheological parameters; correction coefficient; pumping power; non-Newtonian fluid.
