Alfred is Specializing in promoting selective ore breakage using various abrasion techniques to optimize Grade Engineering.

Alfred is embarking on the study of using the characteristics of surface breakage of ores as a new learning concept to increase the feed upgrade. Furthermore, the findings of the studies will be treated as an input to the next-gen VSI (Vertical Shaft Impactor).
Alfred is also interested in ore characterization with access to a wide range of breakage possibilities as well as ways of characterizing particle texture. Proofing some ore types, the outer layer of each particle may contain higher grade material than the inner core. Using the right techniques for particle texture characterization will also be a key component of this project.

Alfred is known as someone who is goal orientated, tech-savvy and highly organized individual with the spirit of excellence, creativity and an approachable manner. In work, Alfred takes every task in a responsible manner. In his previous study, Alfred has published a paper introduces a pioneering use of the material point method (MPM) in a three-dimensional analysis of a field-scale landslide and was awarded “Excellence in Mine Safety 2016”. 

This is an award for the most outstanding undergraduate or postgraduate mining engineering thesis with a particular emphasis on aspects of mine safety. Additionally I have been involved heavily with my local community by volunteering in multiple charity events which equipped me to be a team player with people from multiple cultural background.


Alfred engages with a variety of departments in a mining company. He has two-year experience working on the mine site in both the field (hands-on) and office. My responsibilities included numerical modeling and design of slope, surveying, site investigation, assisting the geotechnical team by installing drill rig and mine equipment with minimal supervision, developing an on-site safety manual, designing a drill and blast in open pit operation in challenging location and documentation of monitoring data. This requires him to always stay fit 24/7 and walks for few hours on-site dailies. Before his academic career, Alfred has achieved various skillset in his previous workplace.
