You have a hypothesis, you do an experiment, and then you either confirm your initial idea or you don’t. But for me, that’s less of a challenge and more of a learning opportunity for the next project.

                  

Research is an active, diligent and systematic process of inquiry in order to discover, interpret or revise facts, events, behaviors or theories, or to make practical applications with the help of such facts, laws or theories.

 

We are building toward a future that centers on collaboration—on breaking down barriers and working together across distances, across disciplines, and across institutions and organizations for the good of science.

 

Major Research Interest

“Raw materials including minerals and metals to make electric vehicles, batteries, wind turbines, and solar panels, are at the heart of the green deal since the energy transition is a switch from fossil fuels to metals. Therefore, the demand for minerals, which are essential to the growth and maintenance of civilization, is rising for the global energy transition. Since the majority of mined ores need to be processed before being turned into usable metals or finished mineral commodities, mineral processing, which is the use of physical or chemical means (gravity separation, magnetic separation, flotation, electrostatic separation, leaching, etc.) to process ores, makes contributions to all areas of technology regards to scientific concepts, engineering principles, products, and processing. In other words, the chemical industry, municipal and industrial waste treatment, and recycling, heavily utilize mineral processing technologies. Moreover, metal recycling—the process of turning scrap metal into new metal products—should be practiced to lower greenhouse gas emissions, protect natural resources, and control energy usage. A good waste collection system, separation and classification processes, and measures have been started to be taken in the world to encourage the metal recycling industry. As a result, mineral processing, particularly extractive metallurgy, which has been disregarded for years, has begun to assume a crucial role in the electrification of the world.”

 

Ore grinding in froth flotation is an important step to liberate the valuable mineral particles from the gangue (Forssberg et al., 1993). When considering particle shape in minerals processing, comminution is of particular interest as this is the process where the particles attain their shape which in turn affects classification and separation stages downstream. Studying the shape characteristics of progeny particles can also be used to interpret breakage mechanisms within milling devices and in some instances, can even be related to the degree of liberation (Leroy et al., 2011). Particle shape can have an impact on numerous processes through its effect on drag coefficients, rheology, and particle bubble interactions.

 

Powders are used extensively across a wide range of industries- they possess many valuable properties and benefits. However, they are also challenging materials with bulk flow properties that are difficult to predict, even within simple process operations. They change their behavior and performance depending on their environment- conditions, etc. Poor understanding of a powder's behavior in response to these behaviors can lead to production stoppages, inefficiency and poor quality or out of spec products.

Though flotation was first used in the early 1900s and has undergone extensive research and development, it is still not fully understood and is still comparatively ineffective. Because the flotation process, which is actually fairly complex, is influenced by roughly 100 different factors. Additionally, it makes control more difficult due to the frequent interactions between the flotation factors and the complicated, non-linear correlations among the several factors. Although it might not be essential to manipulate or measure each of these variables at the same time in order to get excellent process control results, each of these factors and how they affect the flotation procedure should be taken into account. In this context, it is suggested that particle properties (size distribution, shape, degree of mineral liberation) are among the most important factors, especially from the point of view of advanced flotation control and optimizing flotation control.
