Flotation is a conceptually simple operation; however, as multiphase process with inherent instability, it exhibits complex dynamics. One of the most efficient ways to increase flotation performance by implementing advanced controllers, such Model Predictive Control (MPC). This type controller very dependent on model that represents dynamics process. Although development one crucial parts in MP...

Nickel is an important element in the metal alloy industry. In Indonesia, nickel resources are found many areas form of rocks such as pyrophyllite. Froth flotation a method commonly used mining industry to extract metals from mineral rocks. However, concentrates yields tend be relatively low. This often influenced by several factors pH solutions and stirring speed process. Therefore, this study...

snore loudly, and as she could not be roused, the door was forced, and the girl was found lying flat on the floor quite insensible, her breathing stertorous, eyes semi-closed, jaws locked, features distorted, and a stream of bloody froth running out from both the angles of the mouth, her muscles rigid, her dress saturated with urine, voided involuntarily, with violent convulsions occurring almo...
