During the , frothers help create the ideal hydrodynamic conditions such as bubble size and gas holdup required within the pulp in the cell. They generate that is stable enough to hold collected minerals on top of the pulp, mobile enough for removal, and decays quickly to assist with downstream operations.read more
However, sometimes the ore we are using also has other sulphides present in it as impurities. For example, lead sulphide generally has zinc sulphide also present as impurity which will also float in the froth floatation process along with the lead sulphide. To make sure that lead sulphide floats but zinc sulphide do not float, we add depressants.read more
Activators, depressants, and pH regulators are often referred to as modifiers or regulators of the flotation process. The main purpose of these reagents is to modify the action of the collector on mineral surfaces and as a consequence govern the selectivity of the flotation process.read more
