Process research partnership
Research cooperation on the extraction and crushing quartz using high pulsed power
The French company ITHPP - Alcen has developed
expertise in the use of pulsed power for various applications, including mining .
As preliminary tests showed, it is possible to use the technology developed by the company in the context of the PAL project. Research are being made to apply the technology in a real world environment on a large scale.

An important contributor to the research effort is the CTMP. This acronym stands for “Centre de Technologie Minérale et de Plasturgie” (Mineral and Plastic Technology Center ), and they are situated in Thetford Mines (Québec), Canada. CTMP is a recognized Research Center in the fields of minerals and plastics. It has a seasoned team of scientific researchers and technicians specializing in the characterization and treatment of such material. They are equipped with state-of-the-art scientific equipment to precisely determine all composing elements of any plastic or mineral substrate, to analyze their characteristics and asses their properties. It has numerous industrial and institutional partners, including Quebec government Ministry of Superior Education, Research and Science.
PAL partnered with both ITHPP-Alcen and CTMP to develop advanced quartz extraction and silicon purification methods to come up with a true 21st Century industrial process: not only does it yield a very low environmental imprint while greatly enhancing workers’ safety, but it greatly reduced the cost of capitalization and operation by eliminating explosives and crushing equipment required in traditional extraction and purification processes.
