One of the main tasks arising in the development of the technology of area upward sulfur smelting is the study of integral characteristics of the flow (critical velocities and specific head losses) of the sulfur-water mixture during its movement in the permeable zone, which is the main transport link of the technological scheme.

Reliability and efficiency of hydrotransportation systems depends not only on the use of modern high-efficiency and highly reliable equipment, but also on the possibility of regulating the operation of such systems at various changes in the technological cycle of mineral processing at mining enterprises.

One of the options for hydraulic transportation of bulk materials in difficult mining conditions are cascade devices that allow to feed the pulp from a great height.

Analysis of the work of hydrotransport complexes at mining enterprises shows that so far the efficiency of hydrotransport does not correspond to the technical capabilities of this type of transportation ...

Anomalous influence of various surface-active substances (surfactants) on the hydraulic characteristics of suspended flows and flows of homogeneous liquid should be studied in the design, operation and calculation of water conduits and slurry lines at the processing plants of non-ferrous and ferrous metallurgy, coal hydromines, etc. ...
