At the stage of exploratory design the problem of the choice of technology for calcareous rock cleaning from clay and
karst intrusions is solved. Decision is made, which scheme of raw material cleaning complex devices chain should be
given preference. Similar problem is examined, which took place at designing Chanvin open pit depth horizons mining.
The article introduces the results of exploratory design and development of rational flow sheets for limestone cleaning
complexes in order to compare their parameters and technical-economic indices. The present article examines variants

of complexes technology flow sheets on the basis of native and foreign equipment; technical-economic estimation of
the compared variants of complex flow sheets is introduced.

Key words: raw material dry cleaning; clay intrusions; screen; limestone cleaning complex; qualitative-weighted flow
sheet; capacity; profitability index.
