In the present scientific work assessed current status of question about grinding stage effect to electrochemistry parameters of operation preparation slurry before intermediate selective flotation. Showed needs of more detail study chemical reactions in the slurry preparation and flotation processes.At example of Abiz deposit ores has been offer new methodology. The ores are polymetallic sulphide type and the one are most difficult for mineral processing. The methodology allows increase information base during fl...

Due to the global problem of desertification, the demand in the diagnostics of the soil forming in the desert conditions is increased. The desert varnish and the vesicular (porous) crust horizon are distinctive morphological features of desert landscapes and, at the same time, generally recognized features of desert soil formation, being commonly referred to as the yermic horizons in different sub-groups within reference groups of desert soils. The objects of the present study were the surface horizons of vesicula...
