|Once or twice a year, a salt water vessel (Lady Doris, Yulia, Cornelia and Trudy) brings kaolin clay here to discharge at the Port Terminal. After discharge, the clay is mixed with water, creating a slurry that will then go to local paper companies. This has become a new local industry at Lake Superior Warehousing, at the Port Authority. Below is some information from the Port Authority’s Summer, 2013 issue of their quarterly, North Star Port.
Kaolin is a hydrated aluminum silicate crystalline mineral used as a bulking agent or filler in a variety of industries including ceramics, paper, paint, plastics, rubber, sealant, adhesive and chemicals manufacturing. This particular clay adds gloss/shininess in papermaking and is being mined, refined and shipped by IMERYS.
The world’s largest producer of quality kaolin, IMERYS has deposits and production plants in the UK, U.S., Australia and Brazil. The product arrives in bulk as a powder, which is conveyed indoors to a building at the Port Terminal for further processing into a slurry for final delivery by tanker truck to customers in the region.You can buy a one pound jar of Kaolin Clay powder for only $5.99 on Amazon!
