The company operates an ilmenite (titanium oxide ore) mine at Lac Allard [fr] (aka Lake Tio)[1] in northern Quebec, and in the southern Quebec municipality of Sorel-Tracy[2] operates refining facilities that produce titanium dioxide, pig iron, steel, and other metal products.

[1] The smelter uses a development of the 1940 sulfate process to produce titanium dioxide; the iron is a by-product.

[7] In 1981 after a worldwide fall in copper prices, Standard Oil of Ohio (SOHIO) acquired Kennecott.

[12] In March 2004 the president of QIT was Pat Fiore, and he was concerned that at the time his operation was supplying 15% of the market, and running at 70% capacity because of the closure of three clients over the previous 15 years.

[13] In 2008 Hatch partnered with QIT to expand the UGS plant to a capacity of 375,000 tonnes per year.

[14] As of 2009, the company is a wholly owned subsidiary of mining firm Rio Tinto.
