Title: Innovations of Inventor Alvin Maskwa
Introduction
Alvin Maskwa is a notable inventor based in Edmonton, Canada. He has made significant contributions to the field of mineral processing, particularly in the extraction and concentration of heavy minerals from bituminous sands. With a total of three patents to his name, Maskwa's work has advanced the methods used in the industry.
Latest Patents
One of Maskwa's latest patents is focused on the beneficiation of heavy minerals from bituminous sands residues by dry screening. This innovative process allows for the concentration of titanium and zirconium-based minerals from the first stage centrifuge tailings. The tailings are burned off to create a dry, carbon-free mineral mixture, which is then screened into three streams based on particle size. This method effectively rejects silica and clays while concentrating valuable titanium and zirconium minerals.
Another significant patent involves a method for concentrating heavy minerals in the solids tailings derived from the hot water extraction of bituminous sands. This process utilizes an oily mass of solids tailings that contains a high concentration of heavy minerals. By introducing the tailings into a hot reaction zone and agitating them with oxygen, the bitumen and residual coke are burned off, resulting in discrete, dry, and clean product particles. These particles can then be processed to produce a concentrate with enhanced titanium and zirconium content.
Career Highlights
Throughout his career, Alvin Maskwa has worked with various organizations, including Her Majesty the Queen in Right of the Province of Alberta and Canada-Cities Service Ltd. His expertise in mineral processing has made him a valuable asset in these roles.
