These reagents have distinct functions and are added for three purposes : (1) To affect the faces of the minerals to be floated in such a way that they will adhere to the air ...

Modifiers in gold flotation are chemicals used to enhance the effectiveness and selectivity of the flotation process. They play a crucial role in adjusting the chemical environment within the flotation cell to optimize the separation of gold from other minerals. There are several types of modifiers, each serving a specific purpose:
