Sedimentation is used to thicken an incoming feed stream to produce two phases: • Overflow - a stream containing minimal solids. • Underflow - a stream containing minimal liquid. This is accomplished by a number of means inside the thickener: • Settling under the force of gravity. • Addition of reagents such as flocculants,.

Mineral processing - Wikipedia

Before the advent of heavy machinery the raw ore was broken up using hammers wielded by hand, a process called "spalling". Before long, mechanical means were found to achieve this. For instance, stamp mills were used in Samarkand as early as 973. They were also in use in medieval Persia. By the 11th century, stamp.
