Dual-chamber flotation machines are not new. Early forms of the modern dual-chamber pneumatic cells can be traced back to the early 1960s [].Their primary characteristic is that—unlike mechanical flotation cells where the gas-particle adhesion occurs in an agitated, aerated tank—most of the gas-particle adhesion takes place in a separate, high-intensity …
