INTERPRETATION OF FLOTATION DATA FOR THE DESIGN

For a testwork laboratory treating a wide variety of ores, the most useful laboratory flotation machine is probably one with cells of 500, 1000 and 2000g capacities, with a different diameter impeller for each cell, with stainless steel or rubber covered impellers, glass or plastic cell bodies, and requiring an outside source of low pressure air.

The Importance of pH in Flotation 911 Metallurgist

Aug 10, 2015· The Importance of pH in Flotation. In flotation, pH control is a vital method to control selective mineral separation. A standard depressant that is used is an Alkali. An Alkali is any substance that when mixed with Acid will neutralize each other and form a new chemical substance called a BASE. This is very important.
