title: PREPARATION OF TUFF IN THE DUMPS OF BASALT QUARRIES FOR VIBRATION SCREENING
abstract: The article presents the current development of an integrated technology for the processing of tuff in the dumps of basalt pits to highlight the valuable metal fraction and silicate masses. In order to prepare tuff for processing, it is proposed to use the effect of moisture absorption and reduce the strength of tuff when moistened with water, since it has a porous structure and is relatively easy to absorb moisture. This operation, followed by vibratory screening in a small class of -2.5 + 2.0
