The tailing box is a device for tailing disposal. A manual gate valve in the box body is used for controlling the liquid level and tailings discharge capacity. The froth scrapers are arranged on both sides of the flotation tank, and concentrate froth at the upper part of the tank body is scraped into the froth tank when driven by the motor. 7.
To have a positive control over flotation, it is necessary to be able to determine which and to what degree it is. A cheap way to take this measurement, LITMUS PAPER or a pH METER is used. This is a very important measurement for the flotation operator. Some minerals like Iron pyrite will not float well in an alkaline flotation circuit.
