The role of inorganic and organic reagents in the flotation separation

The auxiliary reagents namely lignin sulfonate and soda ash were also added similar to the plant practice. The results seem to suggest that with fatty acids flotation, optimum temperatures may be around 7075 only rather than boiling temperatures. There is even a slight drop in concentrate grade observed during rougher flotation above 75 .

How To Use Your Test Kit

To do a dilution: Look on the left edge of the small tube. You will see the 9 ml mark, and also a 4.5ml (for a 1-1 dilution) and 1.8ml mark (for a 1-5 dilution). If your chlorine test is actually bleaching, use the 1-5 dilution. If it is reading off the scale (a very, very dark red) and you suspect it's higher than 5ppm, use the 1-1 dilution.
