Heads are unlockable cosmetics that alter the look of the players head.. Heads change the colors and animation of the player's head. Many heads reference bosses (e.g. Time Keeper Mask), Game mechanics (e.g. Boss Stem Cells) or Dead Cells, Motion Twin and Evil Empire (e.g. Evil Minion Head). All heads are purely cosmetic.

The Jameson Cell is a high intensity flotation cell in which pulp and air are brought together in a co-current descending flow in a vertical tube called the downcomer. The pulp is introduced into the downcomer through a slurry lens orifice to produce a high velocity jet that generates violent mixing and fine bubble size.

Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry, the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,, and pumped down the

The analysis, nevertheless, does confirm why circuits are used in flotation: they increase selectivity between floatable particles (in addition to cleaners damping entrainment, Section 12.10.2).The benefit of the circuit, the circulating load, is also the "cost": circulating loads mean increased stage (i.e., cell) volume is required.
