Antimony has a long and diverse history of applications, concerns about its future supply have emerged in recent years. Stibnite-bearing ores continue to be the main source this critical element, although sourcing from secondary resources (e.g. mine tailings) is becoming increasingly relevant yet technically challenging. In sense, froth flotation plays key role recovery stibnite both sources. v...

The mysterious stability of nanobubbles on surfaces is a puzzle baffling soft matter and colloid scientists. Bubbles inside a fluid tend to be spherical, but surface bubbles have the appearance of blisters with typical widths of 1000 nanometers (nm) and heights of 20 nm. The existence of surface bubbles was proposed to explain the extremely long range and the magnitude of the strongly attractiv...

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...

Inorganic electrolytes are assumed to significantly impact the flotation performance of graphite resources; however, underlying mechanism is still unclear. In this work, effect three inorganic salts, including KCl, MgCl2, and AlCl3, was studied on graphite. Flotation results indicated increased recovery with addition KCl regardless pulp pH. MgCl2 improved under acidic slightly alkaline conditio...
