In autogenous crushers, the rock to be crushed also provides the crushing force. Crushing is accomplished by the tumbling action of the rock. Flexible crushing circuits can be constructed so that hard ores, as well as soft ores, can be processed. Wet, sticky ores can be processed in autog enous m ills, w hile t he same ore would
May 10, 2019 The rock may or may not be actually deformed in the direction of the foliation, although a strong foliation probably is a sign of high strain. Schists are commonly described in terms of their predominant minerals. This specimen from Manhattan, for example, would be called a mica schist because the flat, shiny grains of mica are so abundant.
