In 2020, the Quebec Government launched its 5-year plan to develop critical and strategic minerals, providing support for companies involved in this sector. Yesterday, the Quebec Minister of Natural Resources and Forests, Mme Maïté Blanchette Vézina ...
Iron phosphating： The result is a light or medium phosphate coat. We use iron phosphate to offer moderate corrosion protection. It also serves as a primer for additional coatings. Zinc Phosphating: The zinc phosphating process provides a thicker coating than iron phosphating. This results in a better adhesion of paint and enhanced corrosion ...

Modern phosphate mining involves complete removal of the land—plants, animals, soil, water, even bedrock—and then its approximate reconstruction minus the phosphate. The steps are as follows: The area to be mined is first stripped of vegetation and the water table is lowered, typically by digging a deep trench around the area.
