1886 Chem. News 10 Sept. 131/1 Working with the samarskite earths, fractional precipitation with oxalic acid separates first erbia, holmia, and thulia, then terbia, and lastly yttria.

1907 H. E. Roscoe & C. Schorlemmer Treat. Chem. II. 784 Erbia..has been shown..to consist of at least four earths, the true erbia, holmia, thulia and dysprosia.

1924 J. W. Mellor Comprehensive Treat. Inorg. & Theoret. Chem. V. xxxviii. 698 C. James has described processes for the extraction of thulia from ytterspar (Norwegian xenotime), euxenite, and a Norwegian columbate.

1968 C. A. Hampel Encycl. Chem. Elem. 718/2 Should the demand arise, thulia, Tm₂O₃, could be isolated readily, as one of a number of individual rare earth by-products from the current (1967) commercial production of yttria by ion exchange, at a rate exceeding 1000 pounds per annum.
