Transcribed image text: Working for OK MetLabs, you receive a sample of copper ore from Ray Mining Ltd and conduct a flotation test on 10 kg of ore (feed grade % copper) to try and recover the copper. After the first flotation, you obtain a concentrate with a copper grade of 9 %, with a recovery of 97 %. The recovery is good, but the grade is too low for this to be worthwhile.

Mineral Processing Introduction
· Modifiers may activate poorly floating minerals such as sphalerite, or may depress certain minerals, so that a differential flotation can be performed on a complex ore. Chemicals that change the pH of the slurry are also used as modifiers. pH modifiers include lime, soda ash, sulfuric acid; can act as activators and/or depressants by controlling the alkalinity and acidity of the slurry.
