The 'dying away' of froth after the rougher concentrate had been removed suggests that there is no floatable talc left - either previously recovered or depressed. Finally, lower residence times are great - less equipment, lower costs - however when you have an existing circuit, there needs to be a significant economic incentive to change anything.
